Cirolanidae
Cirolanidae is a family of isopods, a group of crustaceans commonly known as pill bugs or sow bugs. However, Cirolanidae are distinguished by their mostly marine habitat, unlike their terrestrial relatives. These isopods are primarily found in the ocean, often in shallow waters and coastal regions. Cirolanidae are recognized for their flattened bodies, segmented legs, and a distinct lack of carapace. They are an important part of marine ecosystems, acting as both scavengers and predators, playing a critical role in the decomposition of organic matter.
Common Names
Cirolanidae are commonly referred to as "sea slaters," "marine sow bugs," or "sea roaches." These names reflect their resemblance to terrestrial isopods, but highlight their marine lifestyle.
Characteristics
Members of Cirolanidae share a number of distinctive characteristics:
- Flattened Body: Their bodies are laterally compressed, allowing them to navigate confined spaces and move easily between rocks and crevices.
- Segmented Legs: They possess seven pairs of legs, all of which are used for locomotion and feeding.
- Absence of Carapace: Unlike some other isopods, Cirolanidae lack a hard outer shell (carapace) that protects the head and thorax.
- Antennae: They have two pairs of antennae, which are used for sensing their surroundings.
- Mouthparts: Their mouthparts are adapted for chewing and grinding, allowing them to consume a variety of food sources.
Environments
Cirolanidae are primarily found in marine environments, particularly in shallow waters and coastal regions. They can be found in a range of habitats, including:
- Intertidal Zones: These are areas of the coastline that are exposed to air at low tide and submerged at high tide.
- Rocky Shores: Cirolanidae often hide under rocks and in crevices.
- Seaweed Beds: They can be found among algae and other seaweeds.
- Coral Reefs: Some species are found in coral reef ecosystems.
