The body plan of the cyphonautes larva of bryozoans prevents high clearance rates: comparison with the pluteus and a growth model.
First, morphological and behavioral studies show that a cyphonautes larva bears a pyriform organ that secretes a thin mucous sheet that aids the larva in locomotion and attaches the larva temporarily to the substratum (Stricker 1988).
Membranipora membranacea (Superfamily Membraniporoidea): Feeding Cyphonautes Larva
Late-stage larvae of Membranipora membranacea are similar in shape to a blunt-ended triangle covered in a bivalved shell and are commonly referred to as a cyphonautes larva (Fig.
The cyphonautes larva of Membranipora membranacea and the nonfeeding larva of Bugula neritina each have a single pair of serotonergic neural plate cells within their respective apical discs (this paper and Pires and Woollacott, 1997).
Versatile ciliary behaviour in capture of particles by the bryozoan cyphonautes larva.
An analogous situation has been described for the cyphonautes larva of bryozoans, in which ciliated band length does not increase proportionately to body volume during growth and development (McEdward and Strathmann, 1987).
A second hypothesis is that particles are halted by a sieve formed by stationary laterofrontal cilia, as observed for the cyphonautes larva of bryozoans (Strathmann and McEdward, 1986).
