Quantity 25 of this authoritative evaluation sequence maintains the excessive average set by way of the editors some time past. Marine biologists in every single place have come to worth and luxuriate in the wide range of thought-provoking papers written through invited specialists. during this quantity are stories of 4 animal teams which span the total variety of the marine foodstuff chain. The function of parasites in ecology is a becoming curiosity and the parasites of zooplankton are defined intimately for the 1st time. points of thegastropods, cephalopods and fish lifestyles also are tested intimately.

Sample text

When the settlement of larvae occurs within adult phoronid aggregations, which seem attractive to actinotrochs, the nearest-neighbour distances are not limiting in the settlement which occurs randomly (Fig. 22) (Ronan, 1978; personal observations on Phoronis hippocrepia, P. ijimai, P. australis, P . psammophila). Close n-n distances need a stratification of the lophophores to provide a fully tentacular expansion, which is especially observed in clumps of burrowing or encrusting forms. Such a disposition in suspension feeders always requires some water currents to bring food.

The greatest density is 74000 individuals/m2. Emig et al. (1977) recorded P. pallida mainly in fine sand from 2 to 25 m with the highest abundance near 15 m in Port Philip Bay, and from 3 to 8 m in the other Australian waters (Fig. 29). Thomassin and Emig (1980) described P. pa,lZida living exclusively in fine sand from 0 to 13m with the maximal density (about 20 individuals/m2) between 6 and 13 m. Phoronopsis albomaculata. The general occurrence is in soft sediments from sandy mud to clogged coarse sand with a fine fraction, from subtidal areas to about 55 m (Fig.

Hippocrepia ) . 7 . Larva of Phoronopsis harmeri: Actinotrocha harmeri A . harmeri is the larva of Phoronopsis harmeri: this larva has been described by Zimmer (1964) under the name Actinotrocha A and recent unpublished observations have confirmed this parental relationship. Zimmer (1978) established t h a t there was no difference between the larvae of Phoronopsis harmeri and Phoronopsis viridis;it must be remembered t h a t both species are considered as synonyms (Marsden, 1959; Emig, 1971a, 1979) although Zimmer’s (1978) opinion has never been further supported, A .
