Mata Mata

Looks how to spot one

carapace

The mata mata has a rough, dark brown or black carapace with serrated edges and a relatively small plastron. The head is flattened and triangular, with a very wide mouth, a long tubular snout, tiny eyes, and many fleshy flaps and tubercles on the head and neck. These features give it a camouflaged, leaf-like appearance that helps it blend into muddy, debris-filled waters.21

Personality what they are like

Mata matas are generally calm and sedentary, spending most of their time motionless on the bottom of shallow water. They are not aggressive toward people but can be stressed by handling, especially wild-caught individuals. Captive-bred hatchlings may tolerate gentle handling once they are well established.34

Daily activity how busy a day looks

Very low. They are mostly still, lying on the bottom and waiting to ambush prey. A large tub or enclosure (at least 4 ft by 4 ft for adults) with shallow, warm, acidic water is sufficient. They do not swim much and prefer to walk on the muddy bottom.31

Grooming and care the hands-on bits

Maintain excellent water quality with heavy filtration and regular water changes. Keep water warm (80-90°F), acidic (pH 5-6), and tannin-rich. Provide a basking area with a heat lamp (mid-90s°F) and UVB light. Add aquatic plants or artificial plants for hiding. Avoid sharp rocks.34

Home where they are happiest

A large, shallow aquatic enclosure with soft, muddy substrate. Water depth should be only 8-10 inches for adults. They need warm, acidic, tannin-stained water. A basking spot with UVB and heat is recommended. Never release pet turtles into the wild.31

Food basics what goes in the bowl

Carnivorous; primarily eats live fish such as minnows, platies, mollies, guppies, goldfish and sunfish. They may also take night crawlers. They are vacuum feeders, sucking in prey whole. Stock the enclosure with many feeder fish at once.31

Company who they like around

Solitary. They should be housed alone to avoid stress or competition. Not suitable for handling beyond necessary care. They are not dangerous to humans but are best left as display animals.31

The story where it all began

The mata mata has been collected for the international pet trade for decades, particularly prized by hobbyists in Europe and the United States for its bizarre, ancient appearance. It was formerly hunted for meat in parts of South America, but that practice has declined. Today, wild-caught specimens are still exported, though captive breeding is increasing. The species faces threats from habitat loss and collection. In 2020, populations in the Orinoco basin and western Guianas were recognised as a separate species, *Chelus orinocensis*.1456
