Ocypode pallidula Jacquinot in Hombron & Jacquinot

Common Ghost-Crab (Ocypode pallidula)

The Common Ghost-Crab is indigenous in the Indo-Pacific region, where it can be found running about the beaches in search for food, and digging burrows in the sand.

It is a rather small species, reaching a carapace size of about 2,5 cm in diameter.

On the Cook Islands, where the species seems to be very common, it is known by several names, including ‘atike, kalami, kohiti, kohitihiti, ko’iti, tike, tiketike and titorotai.

Ocypode ceratophthalma (Pallas)

Horn-eyed Ghost-Crab (Ocypode ceratophthalma)

The Horn-eyed Ghost-Crab is indigenous to the Indo-Pacific, where it occurs from the coasts of East Africa far into Polynesia, where the animals run about the beaches in search for edible things, including washed up dead fish, or dead sea birds, but also newly hatched sea turtles.

It is a quite large species with a carapace size of up to 8 cm in diameter. It can be distinguished from other related crabs by the eyestalks extending beyond the eyes into long points, those stalks are longer in males, and shorter or almost absent in females.

In Samoa, the species is called avi’ivi’i resp. pa’a.
