Extreme close up! Can you identify this species of crocodilian? 🐊

For #Croctober Day 20 I want to shout out some fun etymology. To the left you see Paludirex, a large mekosuchine who's name means "swamp king". On the right is Gunggamarandu, which translates to "river boss". Both have been named by Jorgo Ristevski Art by Eleanor Pease

Pops the alligator at Gatorland. He was a hatchling when the park opened in 1949. He apparently is also a movie star, having appeared in Indiana Jones and the Temple of Doom. That film takes place in India (filmed in Sri Lanka), where crocodiles live. What were you thinking Spielberg?! #croctober 🐊

Looooooooooooongirostrine #croctober 🐊

Even with a fence between us, it’s still intimidating being this close to such a big Nile croc. #croctober 🐊

At the end you’ll notice this Cuban croc (C. rombifer) blink their third eyelid aka nictitating membrane. This helps protect their eyes underwater, while still allowing them to see. #Croctober #cubancrocodile 🐊

It’s Blondie, a beautiful Nile crocodile! I’ve seen yellow reptiles like this often referred to as xanthic. Mutation? Polygenic morph? Anyone know more? #croctober 🐊

Why are these alligators so very baby? #Croctober 🐊

I don’t use this term lightly, but this is adorable!! Leucistic baby alligator. #CROCtober 🐊

"Can an alligator survive a Canadian winter?", is not a question or a situation we should have to address. www.insidehalton.com/news/alligat...

Replaced teeth from a dwarf crocodile. #croctober 🐊

Friendly #CROCtober reminder that crocodiles have influenced human culture for thousands of years. Here’s a puppet I saw on a recent visit to the Center for Puppetry Arts in Atlanta, GA. 🐊

It’s not the most important thing by a long shot but we shouldn’t just let them have alligators as a symbol for their secret police disappearance prison. I propose taking gators back as the friendly homegrown superpredators they are. 🐊
