Ovalipes punctatus, commonly known as the spotted sand crab, is a species of crab found in coastal areas of the Indo-Pacific region. These crabs are known for their distinctive spotted carapace and their burrowing habits.
Description & Characteristics
Ovalipes punctatus has a broad, flattened carapace that can grow to a maximum size of around 10 cm in width. The carapace is covered in numerous small, white spots, giving the crab its common name. The legs are long and slender, with the claws being particularly large and powerful. The color of the carapace can vary from a light brown to a dark reddish-brown, depending on the environment and the crab’s diet.
Habitat and Occurrence
Ovalipes punctatus is a common inhabitant of sandy shores and mudflats in the Indo-Pacific region. They prefer areas with moderate wave action and a good supply of food. The species is typically found in the intertidal zone, but can also be found in shallow subtidal waters down to a depth of around 50 meters. Ovalipes punctatus is a prominent feature in the neritic zone, which encompasses coastal waters ranging from the intertidal zone to the edge of the continental shelf.
Taxonomy
Ovalipes punctatus belongs to the family Ovalipidae, which is part of the order Decapoda, which in turn is classified under the class Malacostraca. This species is classified within a group that includes many other familiar crustaceans such as lobsters, shrimps, and crayfish.
Feeding
Ovalipes punctatus are primarily carnivorous and feed on a variety of small invertebrates such as worms, mollusks, and other crustaceans. They are opportunistic feeders, meaning they will consume whatever food is readily available in their environment. They use their powerful claws to capture and crush their prey, which they then consume with their mouthparts.
