Ischyroceridae
The Ischyroceridae are a family of marine amphipod crustaceans. They are commonly known as “slender-bodied amphipods” or “ischyrocerid amphipods.” These small crustaceans are characterized by their slender bodies and long, segmented antennae. The family includes over 300 described species, found in a variety of marine habitats worldwide.
Characteristics
Ischyroceridae are typically small, ranging in size from a few millimeters to several centimeters. They are distinguished by their elongated bodies, with a distinct head, thorax, and abdomen. Their most prominent feature is their long, multi-segmented antennae. These antennae are used for sensing the environment and for communication. The body is covered in a thin exoskeleton that they molt as they grow.
Environments
Ischyrocerid amphipods are found in a wide variety of marine environments, including:
- Intertidal zones
- Subtidal zones
- Deep-sea habitats
- Coral reefs
- Seagrass meadows
- Estuaries
They can be found attached to algae, rocks, or other substrates, or they may burrow into the sediment.
Ecology
Ischyroceridae are an important part of the marine food web. They are preyed upon by larger invertebrates and fish. They also play a role in the decomposition of organic matter and the recycling of nutrients.
