Macropodia falcifera, the Cape long-legged spider crab, is a species of marine crab found around the South African coast.

This crab has a small, arrowhead-shaped body, which may be 20 mm in height, and long, spindly legs, which may grow to 60 mm (2.4 in) in length.

Its pincers are considerably sturdier than its legs and are tipped with white claws.

The body is pinkish or reddish, and the legs and pincers are usually a darker red.

[1] The animals often decorate themselves with hydroids or algae, and are often found on sea fans.
