Ranina ranina, the red frog crab[1] or spanner crab,[2] is a species of edible crab,[3] the only extant species in its genus.[4]

Description

It may grow up to 150 millimetres (5.9 in) long, and may weigh up to 900 grams (2.0 lb).[5] The carapace is wider at the front, reddish brown in color, with ten white spots.[2] Ranina ranina is mainly nocturnal, and remains buried in the sand during the day.[6]

Fishery

The species is commercially exploited over much of its range, and in Queensland, Australia, only adults above 100 mm (3.9 in) carapace length may be landed.[7] In the Philippines in 2008, prices for Ranina ranina were around 200–300 pesos per kilogram.[2]
