Calcinus anani Poupin & McLaughlin, 1998
Calcinus anani is a hermit crab from the family Diogenidae - The family of left-handed hermit crabs. This means the left scissors are larger than the right ones.
The eyestalk is uniformly white or pale orange and fades distally. Antennae peduncles with orange segments, white or cream distal segments. Antennae stalks orange. Pincers are bright orange or brown and fade on the distal half of the fingers. Running legs are light orange with dark orange stripes; Stripes merge into a complicated network.
Distribution: Western and Central Pacific: from Japan to French Polynesia. Depth: 18 to 262 m, more commonly 100 to 250 m.
Often used snail shells of the families Muricidae (Muricopsis), Fasciolariidae (Fasciolaria, Latirus) and Bursidae (Bursa).
The small hermit crab Calcinus anani was described from French Polynesia, and specimens with slight morphological differences were subsequently reported from Japan. Despite their similar appearance, scientific studies separated the two species into Calcinus anani and Caclinus fuscus.
Both species also differ in their area of occurrence and water depth. They have different geographical distributions; Calcinus fuscus from Japan to the Philippines, Papua New Guinea and New Caledonia, the occurrence of Calcinus anani is only known from French Polynesia. In addition, Calcinus fuscus lives at shallower depths than its sister species Calcinus anani.
Calcinus anani is usually found quite deep on seaward reefs. They usually seem to live at depths of 100m. Beyond that, little is known about this small hermit crab.
