Sea Hare

Aplysia punctata & Aplysia fasciata

Named for their ear-like flaps, sea hares graze on seaweeds and can produce a purple ink when disturbed. Sometimes they gather in groups, laying spaghetti-like egg masses on rocks or algae. Around Lihou, you might spot them in calm pools or among kelp fronds, their gentle movements disguised by the surrounding algae.

  • Habitat: Eelgrass beds, rocky reefs, and seaweed-covered areas in shallow waters.
  • When to See: Common in warmer months, particularly late summer.
  • Length: A. fasciata can exceed 30 cm, A. punctata around 15–20 cm
