The object of the present study is the psychrophilic demo-sponge Amphilectus lobatus (Montagu, 1814) (Demospongiae: Poecilosclerida
), a widespread species in the White Sea.
The percentage distribution (by order) of sponges showed that the Order Halichondrida had the highest species composition (31.25%), followed by Leucosolenida, Axinellida, Hadromerida, and Poecilosclerida
each with 12.5%.
Menegola C, Santos GJG, Moraes F, Murici G (2011) Three new species of Strongylacidon (Chondropsidae: Poecilosclerida
: Demospongiae) from northeast Brazil, with new morphological characters for family.
Seasonal patterns of toxicity in benthic invertebrates: the encrusting sponge Crambe crambe (Poecilosclerida
Several clades were recovered that in the present sample set consisted exclusively of HMA taxa (Verongida, Agelasida (Agelas)), while the Poecilosclerida
(sensu stricto) clade with representatives from six families consisted exclusively of LMA species (Fig.
Comparisons of the DNA sequence of the mitochondrial cytochrome c oxidase subunit I gene (COI) between each form of Tedania and other genera representing the order Poecilosclerida
that were available in GenBank were made to determine if the unusual form of Tedania could be genetically distinguished from T.
Growth dynamics and mortality of the encrusting sponge Crambe crambe (Poecilosclerida
) in contrasting habitats: correlation with population structure and investment in defense.
The reproductive development of the Demospongiae species Halisarca dujardini (Halisarcida), Myxilla incrustans and Iophon piceus (Poecilosclerida
) from Chupa Inlet (Kandalaksha Bay, the White Sea) was studied histologically during 1982-1994 and 1997.
Ultrastructure de la larve parenchymella d'Hamigera hamigera (Schmidt) (Demosponge, Poecilosclerida
The morphology of the epidermis of larvae of Tedania ignis (subclass Poecilosclerida
) closely approximates that described for larvae of the haplosclerid demosponge Haliclona tubifera (Woollacott, 1993).
Latrunculiidae is one of three sponge families that do not possess chelae microscleres, but which Levi (1973) (following Topsent, 1928) assigned to the order Poecilosclerida
