Common name: spotted sea hare
General information
The Spotted Sea Hare, scientifically known as Aplysia punctata, is a distinctive marine gastropod mollusk. It is a member of the Aplysiidae family, commonly referred to as sea hares due to their large, rabbit-like 'ears' which are actually rhinophores that aid in sensing the environment. This species is known for its ability to release a cloud of purple ink as a defense mechanism against predators.

Care
Sea Hares are herbivorous and require a diet rich in macroalgae, which also helps them blend into their surroundings. They are sensitive to water quality and require a well-established aquarium with stable parameters. Due to their large size and appetite, they are best suited for larger systems where they can roam and forage without disturbing smaller, more delicate tank inhabitants.
Reproduction
Spotted Sea Hares are hermaphrodites, possessing both male and female reproductive organs. They can form mating chains where one individual acts as a male to the one in front and as a female to the one behind. They lay eggs in long gelatinous strings, which can be seen attached to rocks or other surfaces in the aquarium.
Symbiosis
While not known for specific symbiotic relationships like clownfish and anemones, Sea Hares do play a role in the ecosystem by controlling algae growth, which can benefit other tank inhabitants by maintaining water quality and reducing competition for resources.
Habitat
Aplysia punctata is found in shallow waters along the European coastline, from the Mediterranean Sea to the North Atlantic Ocean. They prefer rocky substrates and seagrass beds where they can find ample food and shelter.
