Petal-like tentacles encircling puckered mouths distinguish a cluster of anemones collected off Yachats. Anthopleura elegantissima feeds when covered by water. Exposed by the tide, it contracts and closes. Fragments of shell and gravel normally cover the trunk. Anthopleura multiplies by sexual reproduction or by lengthwise division into two new animals. Spreading colonies form densely crowded beds. Fronded sea slug browses the bottom of the author's aquarium (above). Sea slugs, or nudi branchs, lack the limestone shells that house most land snails, their kin. Antlerlike sense organs of red and blue adorn the head of a tawny-fringed sea slug. Hungry maw of a sea cucumber (Cucumaria miniata) gapes red. Clumps of tentacles wreathe the mouth; tube feet stripe the body.
