Life in the wild

How this species lives in its natural environment, with the climate, shelters and resources it needs.

Species overview

The mata mata turtle is an extraordinary example of aquatic camouflage, going almost unnoticed among submerged leaves.

Natural habitat

It inhabits slow waters, backwaters, and lagoons in jungle areas, where muddy bottoms and submerged vegetation offer perfect camouflage.

Behavior

It remains motionless for long periods, waiting for fish to get close enough to suck them in with a quick mouth movement.

Special features

Its flattened head, wide neck, and rough shell mimic decomposing branches and leaves. It is an almost pure ambush predator.

Conservation and threats

Capture for trade and alteration of waterways can impact its populations. Its wide distribution gives it some margin, but requires monitoring.

Curiosities

Striking details about this species that show its biology and ecology in a different way.

  • 🌍Its appearance resembles bark and decomposing leaves, allowing it to go unnoticed on the bottom.
  • ✨It does not actively pursue its prey but waits motionless until they pass nearby.
  • 🔎It requires large, very specific water bodies that are difficult to replicate in captivity.
  • 🧠International trade has impacted some populations, so its keeping is regulated in many places.

Welfare profile

Light, temperature, and environmentHigh

Water quality must be very stable, with efficient filtration but without strong currents.

Handling and stressHigh

Direct handling should be avoided as much as possible; its weight and shape make it easy to injure if not held correctly.
