    I’m inclined to think that you shouldn’t smile at this beaste’s cousins although he’s probably from further south and east and used to rougher waters

    (The ‘merican one, not the critically endangered one from China).

    Clues include snout shape and length, divided nostrils and lack of a lateral notch for receiving the big fangs from the lower jaw.

    I was thinking further South in Amazonia … a big one? if I am correct the first captive breeding outside its native range was at Aalborg Zoo in 2013.

      It isn’t that species. Those guys have the bony nostrils united into a single opening, have relatively smaller fenestrae on the skull table (behind the eyes), and have prominent pair of oblique ridges on each side of the snout.
