  • Life in Cold Blood causes sale surge.

    From UKPets.co.uk, we have this interesting bit of news:

    Life In Cold Blood Sells Reptiles
    According to the UK pet store chain, Pets at Home, more people than ever are interested in owning a reptile as a pet, thanks to BBC’s Life in Cold Blood series. The company reports that sales of Fire-bellied Newts and Albino Clawed Frogs have more than doubled in some stores.

    Following the debut of the Sir David Attenborough series on 3rd February, and its second instalment[sic] the following week, Pets at Home received a surge of enquiries from customers regarding keeping reptiles and amphibians as pets.

    Follow the link for more. I think that this is just awesome that a documentary can spark the public’s interest this much. it will be interesting to see if an effect similar to this will be seen when the series hits U.S. shores.

    Till then, I wait…and remind folks that while the interest in owning a reptile as a pet is great; do make sure that you have done your homework on the particular species that you are interested in maintaining. After all, we are talking about living beings here; not toys.

  • Lunar eclipse tonight.

    Just reminding folks living in the states about the lunar eclipse tonight. Unlike a lot of other times when this happens, it won’t be overly late at night (should start around 5:30, PST, or 1:30 AM – UT 8). Hopefully it should turn out real nice. I’m hoping for a red moon.

    Also for folks living closer to the Pacific, keep your eyes out for any tiny flashes in the sky. There’s a spy satellite that just may come down tonight.

  • Another short day

    Not much to add today. It seems Beelzebufo ampinga was the top story yesterday. I don’t think lightning is going to strike twice today though.

    That said, the American Board of Veterinary Specialties has recently petitioned for the recognition of the reptile and amphibian practice specialty. Exactly what this means for veterinarians, I don’t really know, but it couldn’t hurt to get more recognition.

    The AVMA is currently seeking feedback about this petition from both professionals and the public. Feel free to stop on by and give them your two cents.

    As for any herp vets who might be reading this, care to chime in on exactly what being a recognized specialty actually means?


  • _Beelzebufo ampinga_

    Beelzebufo

    Otherwise known as: “The Shielded Devil Frog,” is a recent discovery made in Madagascar, by scientists from University College in London, and Stony Brook University, in New York. This behemoth was about 4.5 kg (~10lbs) in mass, with a length of 40.6 cm (16 inches). It lived during the late Cretaceous, about 70 mya, and appears to be related to the living genus Ceratophrys; more commonly referred to as: Pac Man frogs*.According to researcher David Krause:

    “It’s not outside the realm of possibility that Beelzebufo took down lizards and mammals and smaller frogs, and even — considering its size — possibly hatchling dinosaurs,”

    I’m sure Dr. Krause either added this bit in for shock value, or because he was being prodded by the journalist interviewing him. It always seems that any creature from the Mesozoic has to always be compared to dinosaurs.

    That said, given the relationship of Beelzebufo ampinga to Ceratophrys, I wouldn’t rule dinosaur eating out of the menu either. The living animals are voracious.

    * Of course, frogs of the genus: Pyxicephalus, are also referred to as Pac Man frogs, which can lead to confusion. One reason why taxonomic names are preferred over common names.


  • The “Dawn Shark” and “Hidden Face”

    As I strolled along internet looking for something to blog about, the only thing that I could find was a report that was mentioned a few days ago.

    As is typical, it features the world’s most popular reptiles: Dinosaurs.

    Eocarcharia and Kryptops
    From left to right: “Fierce eyed Dawn Shark” Eocarcharia dinops and “Old hidden face Kryptops palaios

    In this case, it is two theropods that were described by paleontological superstar Paul Sereno, and somewhat paleo-newbie Steve Brusatte. For members of the Dinosaur Mailing List, Brusatte is well known for his previous work on the internet, as a paleo-journalist. This description is credit well deserved for Steve. So good on him for that.As for the report, what is there to really say. It’s the discovery of two new theropods. In the world of dinosaur diversity, dinosaurs are usually broken up into 3 categories:

    1. Theropoda
    2. Sauropoda
    3. Ornithischia

    In terms of diversity, the previous categories are essentially in reverse order. Easily the most diverse dinosaur group was the Ornithischia. They included “duck billed” hadrosaurs, crested lambeosaur…hadrosaurs, horned ceratopians like Triceratops horridus, armoured stegosaurs and super-armoured ankylosaurs. Two legged hypsilophodonts, and helmeted pachycephalosaurs. Ornithischians were all over the map in terms of diversity.

    Next up we have the sauropoda (or to be more inclusive: the sauropodomorpha). On the outset one might think that these guys weren’t really that diverse. I mean if you’ve seen one long necked, long tailed behemoth, then you’ve seen them all right?

    Er, no.

    Sauropods ranged in size from the super tiny Mussaurus patagonicus*, which topped out at 37cm (15 inches), to titans like Argentinosaurus huinculensis, Sauroposeidon proteles, and Amphicoelias fragillimus; all of which grew to excesses of 39.6m (130ft), and had masses 1,000 times greater, with some estimates as high as 122 metric tonnes!

    Besides this humongous size range, we also had sauropods that had sail-backs (Amargasaurus cazaui), sauropods that had tail clubs and armour like ankylosaurs (Shunosaurus lii, Saltasaurus loricatus). We even had sauropods with strange beaks and short necks (Bonitasaura salgadoi, Brachytrachelopan mesai).

    Finally we come to the theropoda. All are bipedal carnivores (one possible exception in segnosaurs). They came in two size classes: Frickin huge, and medium sized. Some had long necks (Coelophysis bauri), some had display crests (Dilophosaurus wetherilli, Cryolophosaurus ellioti). Many show reduction in arm size, with Tyrannosaurus rex and Carnotaurus sastrei taking the cake for tiniest arms. There was also one weird group that had sail-backs and crocodile like heads (the spinosaurs). Still, in terms of overall diversity, a theropod was a theropod.

    Oh, and one group spawned birds, if you’re into that angle.

    It never ceases to amaze me at how often the Dinosaur Mailing list, or dinosaur related websites, devote so much time to theropods. Even news stories seem to put more focus on the big meat eaters rather than the numerous plant eaters. Heck just look at how often we watched theropods fight in the Jurassic Park movies (do you know there was never a scene in the JP movies where a theropod attacked a plant eater?).

    One is forced to ask why that is. I believe the answer lies in the ecology alluded to above. Though sauropods and ornithischians were a highly diverse bunch, they were all herbivores. The only carnivorous dinosaurs were theropods.

    To elucidate this hypothesis even further, check out this story on Digg.com:

    Evolution Explains Why Lolcats Control Your Mind

    Psychologists at Yale University found that the human brain is biased towards images of animals. We are more likely to notice a change in an image, if that change involves animals. I’m going to take this one step further and say that not only are we biased towards pictures of animals, but that bias is even stronger for predatory animals. Especially predators that are large enough to pose a threat to ourselves (e.g. lions, tigers, crocodiles, large sharks, and of course: big theropods).

    So there you have it. Theropods might be the plane Jane group of the Dinosauria, but they will always hog the spotlight. Evolution would have it no other way.

    *Technically M.patagonicus wasn’t actually that small. The type specimen was a hatchling. Adults were closer to 5m (16ft) in total length. Still small for a sauropod though.


  • A comment about…comments.

    I think things have finally gotten to the point, where I might need to instate a comments disclaimer. I’ll probably do that later today, but until then:

    1. All first time comments require authorization. Not because I care about what you are going to say, but because I don’t like spam.
    2. If you want to comment on how well done (or not) my site is, that’s fine, but you better mention some specifics, else I’m going to assume more spam.
    3. I suppose I could mention something about not posting porn sites, but that’s basically a spam related problem anyway.

    Basically, post whatever you want; just no spam.

  • Valentine’s advice for the forgotten.

    When children are asked what they want to be when they grow up, most give answers that they are not particularly tied to. Astronaut, police officer, president. Much of the time this is just said to appease the teacher. Some children, though, do know what it is they want to get from life. These kids are the dream chasers.

    Many people give up their dreams too early in life. Far too many are willing to sell off their dreams for instant gratification. Their only regrets coming 15 years down the line when they ask the inevitable:

    “What happened to my life?

    Those of us that never stopped pushing for the goals we had set for ourselves early on in life, will eventually achieve the pride of knowing that we never gave up. We kept reaching for the proverbial brass ring, until we got it. For these folks; determination, discipline, and willing sacrifice are the tools. Pride is the reward, and loneliness is the burden.

    It’s seems so hard for many to understand how someone could have so much of their life planned out in advance. Yet, after a mid-life introspection, it is often these same people that encourage the next generation to never give up on their life goals. So us die hards are obviously doing something right.

    That said; as a dream chaser, one must be prepared to deal with a seemingly endless gauntlet of detractors and nay sayers. They might be parents who encourage your dreams, but advise alternate goals. They might be advisors in school who insist that you try other things to “make sure this is what you want to do.” They are often friends who just don’t get why you don’t like to “party,” or members of the opposite sex who just don’t get you at all.

    Dreamers can often find themselves feeling alone out there, but that’s just because so few people stay on this path in life to begin with. Dreamers are lonely because they have blazed the trail further than any of their peers. While the price for achieving our dreams is often a high one, we wouldn’t be making these sacrifices if we didn’t think it was worth it in the end.

    I guess this was my long-winded way of wishing the dream chasing set good luck for today; the holiday that punishes people for being single, and encourages folks to lose sight of their ultimate goals.

    Today might suck, but it will pass. Don’t let the influx of culture driven hormones, distract you from what you really want in life. Remember that it is more important to live the life you want, than to just live. Never give up, and never lose sight of your goal.

    It’s worth it in the end.


  • On this day in 1809…

    As a biology related site, I would be remiss to not mention that today marks the 199th anniversary of the birth of Darwin.

    More commonly called: Darwin’s Birthday.

    Okay, I have to admit I have a problem with the celebration of people’s birthdays after they have died. As far as I’m concerned, the only reason we celebrate birthdays is so we can remind ourselves of how long we have (personally) been alive on this planet. Once you kick the bucket, the birthdays should stop.

    Now don’t think I’m picking on old Charles here. I have issues with Christians celebrating Christ’s birth, or Americans celebrating Washington, or Lincoln’s birthday. It just doesn’t make any sense to me. Being born, while fascinating from a biological standpoint, really is no big deal. It’s the acts of these people that really made the difference, not their actual existence (though I suppose Christians could argue the Christ analogy).

    But then I’m a misanthrope who places actions above people anyway, so that might be part of my reasoning.

    Besides, it’s not like we don’t celebrate the reason for Darwin’s popularity. Every year, there is a celebration (or at least an observance) of the such and such anniversary of the publication of The Origin of Species (which will be 150 years ago, next year). It was this publication that made Darwin so famous (and infamous).

    And while Darwin did wind up changing world view, it is important to keep in mind what it was that he actually did. Too many people credit Darwin with the concept of evolution, but that concept had been around since Ancient Greece. Jean Baptiste Lamarck, and even Darwin’s father, Erasmus, all made attempts at explaining a known biological phenomena. Namely: life evolves.

    No, what Darwin did with the Origin of Species, was come up with a plausible mechanism for how evolution operated. Not only was it plausible, but it was also testable. Thus, Darwin warrants praise because he removed the nebulous nature of evolution, and grounded it firmly in the realm of science.

    Which isn’t to say we know all there is to know about evolution. Far from it; in fact. Since Darwin’s day, we have learned about how organisms pass their traits to one another, and the importance of genetics to the evolution of new species. Still, the core concepts from Darwin’s day, namely that the environment makes the final decision on who goes and who stays, remains the same.

    Darwin was also responsible for bringing evolution to the forefront. By grounding evolution in the realm of science, Darwin had unintentionally thrown a wrench into the already rickety creationist world view of the time. That Darwin knew the ramifications of his findings, can hardly be doubted. The fact that he waited years after writing various drafts of The Origin of Species, before finally publishing it, stands as a fine testament to his trepidations about his discovery.

    Which brings me to another point. Though Darwin feared retaliation from the public, and the church, for his apparently blasphemous discovery, he feared being scooped even more. For, as many students of evolutionary biology are now well aware (if not, Wikipedia currently has a good rundown of the history.) Alfred Russell Wallace is equally deserving of credit for the theory of Natural Selection. Both men, who had never met, and were working in completely different parts of the globe, had come across the same results. In science this is a veritable slam dunk in terms of the stability of a theory. For if both parties, through independent means, achieve the same results, then chances are quite likely that those results are damned accurate.

    Still, in science, publication is the name of the game, and the goal in this case, was to get all that hard work out into the public eye and thus establish priority. So that is exactly what Darwin did. And while Wallace might have cursed him for beating him to the punch, I’m sure he was happier that it was Darwin who received all the vitriol that would ensue from a populace that was still thoroughly entrenched in a creationary view of life.

    Now here we are, 149 years after the publication of one of the most landmark pieces of work ever created. 149 years after humanity realized that they lived on a planet that was in constant flux, and that the life they saw that day, would not be the same life a million years from now.

    And of course, 199 years after the birth of the man who took a gamble by publishing one of the most blasphemous, heathenous pieces of literature for its day. A gamble that has paid off in spades, with our greater understanding of where life came from, and where it might be going (which is to say nothing for all the medical advances that occurred specifically because we realized that life does evolve).

    So today we celebrate Darwin’s birthday. Still, I don’t like the taste of that saying, and much prefer the one that Skepchick Rebecca uses:

    Happy Darwin Day!

    If it was a few months earlier, I’d say to celebrate by getting your flu shot.
