Ligia kamehameha is a species of terrestrial isopod, commonly known as a “sea slater,” belonging to the family Ligiidae. These crustaceans are adapted to live in coastal environments, often venturing onto land but always maintaining a close association with the ocean.
Description and Characteristics
Ligia kamehameha, like other members of its family, possesses a flattened, segmented body with seven pairs of legs. They are typically grey in color, helping them to blend into their rocky surroundings. Their size can vary depending on the individual, but they are generally considered medium-sized isopods, reaching lengths of up to 2.5 cm. Ligia kamehameha has a distinctive feature that distinguishes it from other isopods: its large, prominent antennae, which are used for sensory purposes.
Habitat and Occurrence
Ligia kamehameha is an intertidal species, meaning it is found in the area between high and low tide marks. Their habitat is typically characterized by rocky shorelines and coastal areas with access to both the ocean and dry land. These isopods are well-adapted to the changing conditions of the intertidal zone, being able to tolerate both periods of immersion and exposure to air. Their distribution extends across a variety of marine zones, from the littoral zone (the area between high and low tide marks) to the supralittoral zone (the area above the high tide mark).
Taxonomy
Ligia kamehameha belongs to the Class: Malacostraca, Order: Isopoda, and Family: Ligiidae. This classification places it within a group of crustaceans known as isopods, which are characterized by their flattened bodies, segmented legs, and the presence of two pairs of antennae. Ligia kamehameha is part of a broader group of crustaceans, the malacostracans, which encompasses a diverse range of species, including crabs, lobsters, and shrimp.
Feeding
Ligia kamehameha is an omnivore, feeding on a variety of organic matter found in its coastal habitat. Their diet includes algae, detritus (decaying plant and animal material), and small invertebrates. They play a role in the decomposition of organic matter, helping to recycle nutrients within the intertidal ecosystem. Their feeding behavior is often observed at night, when they venture out to forage for food, using their sensory antennae to locate potential sources.
