Comprehensive DescriptionRead full entry
This colonial kamptozoan consists of numerous individual zooids that are connected basally by stolons. Each zooid is made up of a calyx and a stalk, measuring approximately 2 mm in total height. The cuplike calyx is ringed with ciliated tentacles; these tentacles roll inward when disturbed. Typically, each calyx is oriented obliquely relative to the stalk. Each stalk is composed of long, narrow rigid rods interspaced by one or more short, wide muscular nodes, allowing each zooid to bend. Stalk rods are distinguished by a lack of conspicuous pores. Basal stolons are thin and narrow, measuring 50 μm in diameter, and attach to a variety of substrates or other organisms.
