The Pinstripe Menarambo or Pinstripe Damba, discovered by science in 1991, was native to Lake Sarodrano
in northwest Madagascar but was declared extinct in the wild until recently when a small, critically-endangered population was
discovered in River Sofia floodplains.
Small conservation breeding projects are in hand but it is said to be difficult to breed in captivity
and it takes a long time to mature. Moreover, it is unlikely to be possible to return the species in significant numbers to
their degraded, overfished natural habitats beset with invasive species.
Their strong teeth can crack snail shells. They can reach 25cm (10 inches) long.
