About this species

The shell has a distinct, flattened appearance with upturned edges. Unlike other sea turtles, they do not have a pelagic phase.

Enrichment & behavioral stimulation

Flatback Sea Turtle is aquatic — enrichment centers on water quality, basking, and foraging variety.

  • Provide varied water depth with deep areas for swimming and shallow shelves for resting.
  • Add a sturdy dry basking platform under heat and UV.
  • Introduce gentle water movement or aeration for sensory variety.
  • Scatter food in the water to encourage swimming and searching.
  • Include underwater cover and hiding spots to reduce stress.
  • Provide a dry haul-out area for basking and resting.
