@metasuchus @Visceral9000 @TemmieMew I measured Juancho with Luis Sigler on my last visit a couple months ago. He is ~420 cm TL, though it wasn’t ideal as we had to align him to a 360 cm long poll then measure the poll & his DCL.

@cardabiolurker @Visceral9000 @necrowow2 Ah yes, I’m aware, great pictures from him.

@vivek4wild @IUCNssc @incognito9 @atulMbhatnagar @deespeak @indian_pitta @PATRICI55845750 @chandanaroy24 @mharshaips @wti_org_india Absolutely stunning photos! Especially of the largest neotropical predator, well, eventual largest by the looks of it 😂

@alexiskrugerr @doc_tellez Very common species that is indeed well known for its ability to run on water.

@TetZoo @bbcstudios @AppleTV @Framestore Amazing work from you especially. Really looking forward to seeing this, keeping my fingers crossed that the crocodilians will be done some justice this time. If not now, please consider the Late Miocene at some point as a certain group within Alligatoridae reached their peak!

@Monstera_atrox @silver_gold4 This was filmed at the border of Brazil & Bolivia in Rio Mamore.

@AndriMagnason By far one of the greatest influences to many current and future crocodilian biologist to this day! It’s an immense shame he left so soon.

Melanosuchus niger, the Black caiman.
Amazon River Peru

@OtorongoLodge Future king of the region right there!

@ApexPredator227 This was also in Bolivia, there is no Black Caiman in the pantanal.

[Jaca @Jacarean]

@ApexPredator227 This was in Bolivia, not Guyana.

@AlliGatoDundee @metasuchus @ArtemijAnd42837 @ausar_the It’s worth adding that these individuals are also from the smallest known Caiman population in terms of average body size. Either way, my point still stands, a 17 ft Caiman is not going to weigh less than a 15 ft gator unless the Caiman is literally a pile of bones.

[Jaca @Jacarean]

@AlliGatoDundee @metasuchus @ArtemijAnd42837 @ausar_the The Caiman is also far less studied than the Alligator with large individuals seldom ever measured while large Alligators are consistently studied. Skulls and the known DCL:TL ratio is enough to prove the Caiman is much larger. A caiman over 5m has also been captured already.

[Jaca @Jacarean]

@AlliGatoDundee @ausar_the Black Caiman are much larger than American Alligators.

@Alexander_M1010 @BrianEngh_Art Spent some time with this species recently, absolutely stunning beast they are.

[Jaca @Jacarean]

@OtorongoLodge Are they closely related to the Piraiba?
