Ebalia granulosa is a species of crab belonging to the family Leucosiidae. This crab species is commonly found in various marine environments, showcasing its adaptability to diverse habitats.
Description & Characteristics
Ebalia granulosa is characterized by its relatively small size, typically reaching a maximum length of around 2 centimeters. Its body is broadly oval in shape, with a smooth and granular surface, giving it a distinctive texture. The carapace, or upper shell, is covered in small, raised granules, which are particularly prominent along the margins. The crab’s legs are relatively short and stout, equipped with sharp claws and spines. The color of Ebalia granulosa can vary depending on its habitat, ranging from pale yellowish-brown to reddish-brown hues.
Habitat and Occurrence
Ebalia granulosa is a common inhabitant of shallow, coastal waters, typically found in depths ranging from the intertidal zone to about 100 meters. This species is often found in association with seagrass beds, rocky reefs, and sandy bottoms. Its distribution spans across the northeastern Atlantic Ocean, extending from the British Isles to the Mediterranean Sea. Ebalia granulosa is considered a prevalent presence in the infralittoral zone, which is the marine zone that lies between the low tide mark and the depth where light levels begin to significantly decrease.
Taxonomy
Ebalia granulosa is scientifically classified within the Class: Malacostraca, Order: Decapoda, and Family: Leucosiidae. This classification places Ebalia granulosa within a group of crustaceans that includes a wide variety of crabs and lobsters. The Leucosiidae family, to which Ebalia granulosa belongs, is characterized by its members possessing a generally flattened carapace and a distinctive, often granular surface.
Feeding
Ebalia granulosa is an omnivorous scavenger, feeding on a variety of organic matter. Its diet includes algae, detritus, small invertebrates, and even dead fish. Its scavenging behavior plays a vital role in marine ecosystems, helping to decompose organic material and recycle nutrients.
