Why would a rattlesnake’s tail glow under black light?
Oct 1, 2021 · original
We recently read a wonderful paper about some snakes’ tails fluorescing under black light. It seemed odd to us that they didn’t mention whether or not an Eastern Diamondback Rattlesnake ( Crotalus adamanteus ) had this same condition, so we checked it out for ourselves. As you can tell by our photograph, the tail of our Eastern Diamondback Rattlesnake does glow quite nicely under black light. You may be asking yourself why in the world is this a thing. Well, that is exactly the kind of thing these scientists asked as well. The paper is attached and worth a read. We especially like the rattle/grass seed head comparison.

Well, after some pretty detailed research, we still don’t know for sure! Check out this paper about a study done on the crocodilians at the St. Augustine Alligator Farm. CLICK HERE TO VIEW PDF DOCUMENT

Crocodylian Head Width Allometry and Phylogenetic Prediction of Body Size in Extinct Crocodyliforms
May 5, 2020 · original
Haley D. O’Brien, Leigha M. Lynch, Kent A. Vliet, John Brueggen, Gregory M. Erickson and Paul M. Gignac2 Synopsis Body size and body-size shifts broadly impact life-history parameters of all animals, which has made accurate body-size estimates for extinct taxa an important component of understanding their paleobiology. Among extinct crocodylians and their precursors (e.g., suchians),several methods have been developed to predict body size from suites of hard-tissue proxies. Nevertheless, many have limited applications due to the disparity of some major suchian groups and biases in the fossil record. Here, we test the utility of head width (HW) as a broadly applicable body-size estimator in living and fossil suchians. We use a dataset of sexually mature male and female individuals (n 1⁄4 76) from a comprehensive sample of extant suchian species encompassing nearly all known taxa (n 1⁄4 22
Divergent Morphology among Populations of the New Guinea Crocodile, Crocodylus novaeguineae (Schmidt, 1928): Diagnosis of an Independent Lineage and Description of a New Species
Sep 26, 2019 · original
Christopher M. Murray1,2, Peter Russo3, Alexander Zorrilla4, and Caleb D. McMahan5 The freshwater crocodile inhabiting Papua New Guinea, currently recognized as Crocodylus novaeguineae, exhibits morphological, molecular, and ecological divergence between the northern and southern versants of the Central Highlands and occupies separate evolutionary trajectories. A robust body of work has long encouraged the formal description of New Guinea crocodiles from the southern versant of the highlands as a distinct lineage with a taxonomy that reflects diagnosed relationships. Here, we use geometric morphometric techniques to assess cranial shape variation between specimens from both versants and add to the diagnostic evidence supporting a more accurate taxonomy. Further, herein, we formally describe the southern variant as a distinct lineage (Hall’s New Guinea Crocodile; Crocodylus halli, new spe

The St. Augustine Alligator Farm Zoological Park is excited to have been a part of this research. You can see from the photos how amazing working with the FLIR camera is, but even more amazing is what we learned from this research. CLICK HERE TO READ FULL ARTICLE

Meeting Karen Allen
Jan 22, 2019 · original
On January 18, 2019 Karen Allen came to the St. Augustine Alligator Farm. John Brueggen, our Director, and his wife, Jen, took her and two of her friends (Joan and Charlynn) on a tour of the Farm. Joan and Karen were in St. Augustine to participate in the 9 th annual St. Augustine Film Festival. Karen may be best known for her role as Marion in Raiders of the Lost Ark, but she has been in many other films, including Animal House, Starman, The Sandlot, Scrooged, The Perfect Storm, A Year By the Sea, and many others. She is now directing films and she screened her first short film, as a director, at the Film Festival. It is called A Tree. A Rock. A Cloud. Karen seemed to be captivated by the animals at the Alligator Farm almost as soon as she walked in the door. We took the time to do an Alligator Extreme photo with her and a twelve foot alligator named Handsome. We then took her to see ou
Crocodiles using tools?
Jan 28, 2018 · original
Using objects as hunting lures is very rare in nature, having been observed in just a handful of species. We report the use of twigs and sticks as bird lures by two crocodilian species. At least one of them uses this method predominantly during the nest-building season of its prey. This is the first known case of a predator not just using objects as lures, but also taking into account the seasonality of prey behavior. It provides a surprising insight into previously unrecognized complexity of archosaurian behavior. CLICK HERE TO READ FULL ARTICLE
Can Crocodiles change color?
Jan 27, 2018 · original
Many species alter skin color to varying degrees and by different mechanisms. Here, we show that some crocodylians modify skin coloration in response to changing light and environmental conditions. Within the Family, Crocodylidae, all members of the genus Crocodylus lightened substantially when transitioned from dark enclosure to white enclosures, whereas Mecistops and Osteolaemus showed little/no change. The two members of the Family Gavialidae showed an opposite response, lightening under darker conditions, while all member of the Family Alligatoridae showed no changes. Observed color changes were rapid and reversible, occurring within 60–90 minutes. The response is visually-mediated and modulated by serum α-melanocyte-stimulating hormone (α-MSH), resulting in redistribution of melanosomes within melanophores. Injection of crocodiles with α-MSH caused the skin to lighten. These results
