The bougainvillid hydroid Clavopsella micbaeli produces clubshaped 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 curytele cnidocysts always in functional position, with the cnidocil apex pointed outwards. The cnidocysts constitute a defensive «stinging armor» protecting the large eggs.

Abstract
The bougainvillid hydroid Clavopsella micbaeli produces clubshaped 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 curytele cnidocysts always in functional position, with the cnidocil apex pointed outwards. The cnidocysts constitute a defensive «stinging armor» protecting the large eggs.File in questo prodotto:
