Aniculus
Aniculus is a genus of porcelain crabs in the family Porcellanidae. Porcelain crabs are decapod crustaceans with flattened, somewhat crab-like bodies and are typically found in coastal waters around the world. They are known for their brightly colored shells, often with intricate patterns and designs.
Common Names
Crabs belonging to the genus Aniculus are commonly referred to as "porcelain crabs" or "decorator crabs" due to their habit of decorating their shells with sponges, algae, and other marine organisms. The specific common names of individual species within the genus may vary based on their geographical distribution.
Characteristics
Aniculus crabs are characterized by the following features:
- Flattened, oval-shaped carapace (shell)
- Long, slender legs, particularly the first pair, which are modified into chelae (claws)
- Brightly colored shells, often with elaborate patterns
- Ability to decorate their shells with sponges, algae, and other marine organisms
- Small size, typically ranging from a few millimeters to several centimeters in length
Environments
Aniculus crabs are predominantly found in shallow, coastal waters, often in association with coral reefs, seagrass beds, and rocky shores. They are typically found in areas with abundant vegetation and shelter, where they can readily camouflage themselves and avoid predators. They are also common in tide pools and intertidal zones.
