Spanner Crab - Ranina ranina
This Spanner Crab - Ranina ranina is also known as Red Frog Crab. Like most crabs, they are nocturnal, coming out at night to feed. They are mostly buried in the sand during day time. Saw this one during a night dive and it doesn't likes our bright dive lights, would scutter away each time we have our dive lights on it. It ran in a funny way, unlike most crabs that swims/moves side way, this was running forward most of the time.
Apparently, this Crab is fairly common when in season and can be found in good numbers at Fish Market, it is supposedly a delicious crab. However, this is my first time seeing this Crab during a dive.
''Ranina ranina'', also known as the frog crab or spanner crab, is a species of edible crab, found throughout tropical and subtropical habitats. It is the only extant species in its genus.
