Neopetrolisthes
Neopetrolisthes is a genus of anomuran decapod crustaceans in the family Petrolisthes, commonly called “rock slater crabs”. These crabs are small, typically less than 2 cm in length, and are characterized by their flattened body shape and prominent, often brightly colored, claws. They are found in a variety of marine environments, primarily rocky intertidal zones and shallow subtidal areas.
Common Names
Neopetrolisthes crabs are commonly called "rock slater crabs" due to their flattened shape and resemblance to woodlice (also known as slaters). They are also sometimes referred to as "rock crabs" or simply "slater crabs".
Characteristics
Neopetrolisthes crabs exhibit several distinguishing characteristics, including:
- Flattened body shape: Their bodies are compressed dorsoventrally, allowing them to wedge into crevices and under rocks.
- Prominent claws: The chelipeds (claws) are often large and brightly colored, used for defense and feeding.
- Short legs: Their legs are short and stout, adapted for clinging to rocks and moving in tight spaces.
- Gill chambers: They have well-developed gill chambers, essential for respiration in their marine habitat.
Environments
Neopetrolisthes crabs are primarily found in rocky intertidal zones and shallow subtidal areas. They prefer areas with abundant algae and crevices for shelter. They can also be found in tide pools, seagrass meadows, and coral reefs.
Distribution
The genus Neopetrolisthes is widely distributed in the Indo-Pacific region, extending from the Red Sea and East Africa to the Pacific Islands and Australia.
