Triops cancriformis, or tadpole shrimp, is a species of tadpole shrimp found in Europe to the Middle East and India. Due to habitat destruction, many populations have recently been lost across its European range, so, the species is considered endangered in the United Kingdom and in several European countries. In captivity they commonly grow up to 6 centimetres (2.4 in); in the wild they can achieve sizes of 11 cm (4.3 in).
