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%.

anchorata (Halichondrida) can be related to the abundance of silica spicules in this species, more than in H.
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).

Systematic revision of the genus Petromica Topsent (Demospongiae: Halichondrida), with a new species from the southwestern Atlantic.
Chemical defense of Hymeniacidon heliophila (Porifera: Halichondrida) against tropical predators.
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., 2002), but COI sequences for four species in two genera of freshwater sponges in Lake Baikal were found to be identical (Schroder et al., 2003).
