SLUGS
|
Hawaii has many types of opisthobranchs some
of which are undescribed species. Some of these will go through population
surges, abundant one year and absent another, or seasonal appearances.
Most live less than a year and will be found near the specific food they
eat. Food includes seaweeds and a wide assortment of small invertebrates
such as sponges, cnidarians, and mollusks. Slugs that feed upon green
seaweed often store algal cells in their mantle for photosynthesis. Sea
Hares produce a purple ink from red algae when disturbed. Others may
produce toxic compounds from food or store stinging cells in the body as defense
against predators. Good places to find them are under stones in the
intertidal zone and shady walls and caverns in deeper water. As with many
invertebrates more will be seen at night.
