Sea hares aren't as fast as their terrestrial namesake, so they've evolved a host of other defenses. One of the most effective is the production of opaline-- a milky, viscous goo that contains chemicals which can fool predators like spiny lobsters into thinking the cloud is their intended target, while the real sea hare makes its escape. The opaline's thick, sticky texture also dampens the lobster's sense of taste and smell, so even if the sea hare is slow to move away its would-be predator won't detect it.
