Bursatella ocelligera is a species of sea slug belonging to the family Aplysiidae. It is commonly known as the “ocellated sea slug” due to its distinctive markings. These slugs are fascinating creatures with unique characteristics and an interesting ecological role.
Description & Characteristics
Bursatella ocelligera is a relatively small sea slug, typically reaching a maximum size of around 5 cm in length. Its body is oval-shaped and flattened, with a prominent mantle that extends over the head and flanks. The most striking feature of Bursatella ocelligera is its coloration. The body is generally a pale grayish-brown, but it is covered with numerous dark brown or black ocelli (eye-like spots), giving it a distinctive, almost mottled appearance. These ocelli, which resemble the eyes of larger animals, are thought to serve as a form of camouflage or deter predators.
Habitat and Occurrence
Bursatella ocelligera is a widely distributed species, found in tropical and subtropical waters around the globe. It is commonly encountered in intertidal zones and shallow subtidal areas, typically inhabiting rocky shores, seagrass beds, and mangrove forests. These slugs are often found in association with seaweed, their primary food source. Bursatella ocelligera is particularly prevalent in the Indo-Pacific region, and it is also found in the Caribbean Sea and the Mediterranean Sea.
Taxonomy
Bursatella ocelligera is classified within the Class: Gastropoda, Order: Aplysiida, and Family: Aplysiidae. This family encompasses a diverse range of sea slugs, including the well-known “sea hares.” Within the family Aplysiidae, Bursatella ocelligera belongs to the genus Bursatella, which contains a small number of similar species.
Feeding
Bursatella ocelligera is an herbivorous sea slug, specializing in feeding on various species of green algae. This species is known to graze heavily on the genus Ulva, commonly known as “sea lettuce,” and is considered an important grazer in its coastal ecosystems.
