Main predators of adults are crocodilians, large snakes, dogs, & felids. Many snakes, birds, & rodents eat young/eggs.
Leaf-like snout & algae on body come in handy since they’re ambush predators. When prey swims by, they stick head out & open mouth as wide as possible, sucking prey into mouth. Camouflage also comes in handy for avoiding predators.
Only leave the water when females lay eggs. Males never leave water.
Females lay 12-28 eggs per clutch.
They’re very shy & don’t often like being handled.
Can be active anytime of day due to being very lazy inactive animals.
Before mating, males repeatedly extend head towards females while opening/closing mouth.
While vision is poor, they have excellent senses of hearing/touch.

Fun Fact(s):
Due to camouflage/hunting strategy, they can catch prey in a split-second.
Occasionally kept as pets due to odd appearance.
Though there’s rural New Zealand town named Matamata which was a shooting location for Lord of the Rings movies, they’re not from there, instead being from South America. Matamata Spanish for “kill kill.”
While almost completely aquatic, they’re actually poor swimmers, instead slowly walking along bottom.
Due to unattractive appearance, some men in South America refer to unattractive women as “mata matas.”
