The percentage distribution (by order) of sponges showed that the Order Halichondrida
had the highest species composition (31.
According to Brusca & Brusca (2003), members of the order Halichondrida have a heavier skeleton composed of spicules than members of the order Poecilosclerida.
anchorata can be explained by the greater presence of spongin, a collagen constituent of the organic skeleton, a feature more representative in mass for members of the order Halichondrida than the inorganic skeleton (Brusca & Brusca, 2003).
Phylogenetic analysis of the order Halichondrida (Porifera, Demospongiae), using 3p-hydroxysterols as chemical characters.
A systematic revision of the central West Atlantic Halichondrida (Demospongiae, Porifera).
Dictyoceratida, Dendroceratida, Verongida, Haplosclerida, Poecilosclerida, Halichondrida, Axinellida, Desmophorida y Homosclerophorida.
Analysis of COI sequences has been successfully applied on the interspecific level, to test hypothesized cospeciation of sponge species in the order Halichondrida
with bacterial symbionts (Erpenbeck et al.
