GENUS LEUCETTA HAECKEL, 1872

Type species: Leucetta primigenia Haeckel, 1872 (by original designation).

Min., minimum; Max., maximum; SD, standard deviation; N, number of spicules measured; N, number of specimens analysed.

L., Leucetta ; t -test value or Mann-Whitney U; * P <0.05. Underlined text indicates Mann–Whitney U test results.

Diagnosis: Leucettidae with a homogeneous organization of the wall and a typical leuconoid aquiferous system. There is neither a clear distinction between the cortex and the choanoskeleton, nor the presence of a distinct layer of subcortical inhalant cavities. The atrium is frequently reduced to a system of exhalant canals that open directly into the osculum or may be a large cavity (modified from Borojevic et al., 2002).
