The eggs are yellow-green, and change after 8–9 days into a brown color before larvae hatch. Mating is most prominent during the summer following water ...
Sea hares form their toxins from compounds they receive from their foods. [7] This is significant because the type of algae the sea hare eats determines the toxins it produces. [ 6 ] A. vaccaria primarily feeds on brown algae, so its toxins are derived from this source and are distinct from sea hares such as A. californica , which feeds on red ...
Aplysiidae is the only family in the superfamily Aplysioidea, within the clade Anaspidea. [1] These animals are commonly called sea hares because, unlike most sea slugs, they are often quite large, and when they are underwater, their rounded body shape and the long rhinophores on their heads mean that their overall shape resembles that of a sitting rabbit or hare.

Their color corresponds with the color of the seaweed they eat: red sea hares have been feeding on red seaweed. This camouflages them from predators. When disturbed, a sea hare can release ink from its ink glands, providing a fluid, smoke-like toxic screen, adversely affecting its predators' olfactory senses while acting as a powerful deterrent.
The Florida Oceanographic Society says that because of their extensive neural circuits -- interconnecting neurons in the brain that pass messages -- sea hares are often utilized in medical research.
