Uristidae
Uristidae is a family of marine isopods, crustaceans that are closely related to pillbugs and slaters. They are characterized by their flattened bodies and the presence of a pair of uropods, which are appendages that extend from the posterior end of the abdomen. Uristidae are commonly found in the intertidal zone and shallow waters of the world’s oceans, often living among seaweed or under rocks.
Common Names
Uristidae are commonly known as sea slaters, sea pillbugs, or marine isopods.
Characteristics
Members of the Uristidae family share several distinctive characteristics:
- Flattened Body: Their bodies are dorsoventrally flattened, allowing them to squeeze into narrow spaces.
- Uropods: They possess a pair of prominent uropods at the end of their abdomen, which help them to swim and maneuver.
- Seven Pairs of Legs: Like other isopods, they have seven pairs of legs, the first pair of which are modified into maxillipeds used for feeding.
- Antennae: Uristidae have two pairs of antennae, one pair of which is very short.
- Size: Most Uristidae species are small, typically measuring less than 2 cm in length.
Environment
Uristidae are primarily found in marine environments, particularly in the intertidal zone and shallow waters. They prefer habitats with abundant seaweed or rocks, where they can find shelter and food. Some species are also found in deeper waters, but these are less common.
