Reptile Identification Contest #5!: One Lucky Winner Will Get 10 SBD!

 Update: CONGRATULATIONS TO @kingmotan FOR THE SUCCESSFUL IDENTIFICATION OF THE MYSTERY REPTILE! 

The identity of the reptile will be revealed tomorrow so feel free to keep on guessing!    

------------------------------------------------------------------------------------------------------

During my herpetology lecture course in college, my professor provided extra credit opportunities to students through identification contests. I found it to be a very fun way to learn to identify local species and I want to bring that educational fun to steemit! This is also a great chance for our newest members to get some valuable steem in their wallets!

Soooo.... CAN YOU IDENTIFY THE PICTURED REPTILE?!   

Contest Rules:

1. You must be able to provide the LATIN, SCIENTIFIC NAME. Common names are often interchangeable or used to describe many different species (it's pretty easy to find scientific names online).
2. Please MESSAGE ME DIRECTLY ON STEEMIT.CHAT (herpetologyguy) with your answer! This ensures that everyone has a chance to try and guess (so please do NOT answer in the comment section)!
3. If you make an incorrect guess, no worries! I allow multiple guesses...within reason (in other words, don't just copy/paste me a huge list of answers, that's no fun!).
4. If someone correctly identifies the animal, I will make a note on this post that the prize has been claimed, but you are more than welcome to continue guessing!
5. If/when a significant amount of time (maybe an hour or two) passes with no correct guesses, I will add a couple clues to help you narrow down your search.

THE PRIZE IS 10 SBD TO THE FIRST INDIVIDUAL WHO MESSAGES ME WITH THE CORRECT ANSWER! 

Clue 1: This reptile is found in freshwater in South America. 

Clue 2: Strictly an aquatic species, this reptile likes shallow water where it lazily hunts for fish and leads a sedentary lifestyle.
