The bougainvillid hydroid Clavopsella michaeli produces club-shaped female gonophores each bearing up to eight large eggs. These eggs are covered by a single layer of isolated cnidocytes in close contact with the oocyte membrane. These cnidocytes have fully‐developed microbasic eurytele cnidocysts always in a functional position, with the cnidocil apex pointed outwards.

Abstract

The bougainvillid hydroid Clavopsella michaeli produces club-shaped female gonophores each bearing up to eight large eggs. These eggs are covered by a single layer of isolated cnidocytes in close contact with the oocyte membrane. These cnidocytes have fully‐developed microbasic eurytele cnidocysts always in a functional position, with the cnidocil apex pointed outwards. The cnidocysts constitute a defensive ≪stinging armor≫ protecting the large eggs.
