Bullidae
The Bullidae, commonly known as bubble shells or diminutive sea hares, are a family of small to medium-sized sea slugs, marine gastropod mollusks in the superfamily Aplysiomorpha. Members of the Bullidae are characterized by their thin, fragile, often translucent shells. The shell is usually ovate, with a wide aperture. Many species have a distinct, sometimes colorful, mantle, which extends beyond the shell, covering much of the animal’s body.
Characteristics
Bullidae are herbivorous and typically feed on algae. They are known for their ability to secrete a thick, slimy mucus that helps protect them from predators and allows them to glide across the seafloor. Some species are able to release a purple ink as a defense mechanism. The reproductive system of Bullidae is complex, with both male and female reproductive organs present in the same individual (hermaphroditism). They are typically internal fertilizers and lay their eggs in long, gelatinous strings.
Habitat and Distribution
Bullidae are found worldwide in tropical and subtropical seas. They inhabit a variety of shallow water environments, including coral reefs, seagrass beds, and rocky shores.
