Idotea linearis, commonly known as the linear idotea, is a species of isopod crustacean belonging to the family Idoteidae. These small, flattened creatures are commonly found in coastal habitats and play an important role in marine ecosystems.
Description & Characteristics
Idotea linearis is characterized by its elongated, segmented body and flattened shape. This species typically grows to a maximum size of around 20 millimeters in length. The body of Idotea linearis is covered in a hard exoskeleton, which provides protection and support. They possess seven pairs of legs, adapted for walking and clinging to surfaces. Their antennae are relatively short and segmented, aiding in sensory perception.
Habitat and Occurrence
Idotea linearis primarily inhabits intertidal zones, often found along rocky shores and in shallow waters. This species can be found in a range of marine zones, from the lower intertidal to the subtidal. Their distribution extends across the North Atlantic Ocean, including the coasts of Europe and North America. They are particularly common in areas with abundant seaweed and algae, providing them with food and shelter.
Taxonomy
Idotea linearis is a member of the Class: Malacostraca, which includes a wide diversity of crustaceans. It belongs to the Order: Isopoda, a group known for their flattened bodies and lack of a carapace. The family: Idoteidae encompasses a number of isopod species adapted to marine environments, and Idotea linearis is a prominent member of this group.
Feeding
Idotea linearis are primarily herbivores, feeding on a variety of algae and seaweed. They play a crucial role in the ecosystem by consuming dead organic matter and algae, contributing to the breakdown of these materials and the recycling of nutrients within the marine environment. This feeding strategy makes Idotea linearis an important component of the food web in their habitats.
