the second one that he named, how do they defend themselves?
They spout ink when disturbed or attacked.
Aplysiidae
Some species spout ink when disturbed or attacked, and they may also swim (rather than crawl) away, using their broad wing-like flaps or parapodia. The ink is extracted from their algal food, rather than being synthesized.

Aplysiidae [SEP] Defenses
Some species spout ink when disturbed or attacked, and they may also swim (rather than crawl) away, using their broad wing-like flaps or parapodia. The ink is extracted from their algal food, rather than being synthesized. Sea hares have two main secretory glands in their mantle cavity. The genus "Aplysia" has proved useful as a model in neurobiology for the study of electrical synapses, which mediate the release of the clouds of ink.
