Creature Feature: Mata mata

Turtles are cute, slow, lovable and most of them would not hurt a fly. Some of them would not mind a vertebrate now and again, but for the most part, they are one of the least objectionable reptiles in the world. It's hard to have a turtle-phobia.


AAAH, REPTILES! Oh, wait...those are actually kinda cute.

Nature just had to make one of the fish-eating turtles as ugly as possible:


Remember, turtles are naturally adorable.

Meet the matamata (Chelus fimbriatus), a turtle native to the Amazon River and some of the surrounding swamps. It is very lazy and very flat; quite easy to mistake for leaves or driftwood from above. Like the three-toed sloth, algae growing on its carapace makes its camouflage even better. It has a 'horn' that allows it to get air while barely moving a muscle. The matamata is probably the real version of a Teenage Mutant Ninja Turtle.



Hanging down from its face and neck are fleshy little projections. Nobody really knows what these are for; they could add to the matamata's already superb camouflage, serve as subtle lures or even be sensory adaptations.



As unsuspecting fish draw near, the matamata opens its mouth to create a small vacuum. Like something out of a cartoon, the fish are sucked in. The matamata cannot chew due to its odd mouth, but with a contraption like that, it does not need to.



Mata mata are native to humid environments. Although they are available in the exotic pet trade, they are not a beginner's turtle; not only are they expensive, but they like slightly acidic water with a high tannin content. If all of that just went WAY over your head, you can't have one.

  1. My grandma hates all reptiles (I'd say amphibians, worms, and even SCORPIONS??? also count by her dementia logic) just because she was bitten by a snake. ""Oh, it's a reptile? In that case, will you go kill it!"
