By contrast, all individuals of the unusual form, from both the mangroves and seagrass, developed one to three (in most cases two) tall and relatively narrow, volcano-shaped mounds (dimensions of the four largest mounds, as height by width [midway between base and peak], were 4.5 x 2.4 cm, 5.2 x 2.0 cm, 8.0 x 2.1 cm, 5.8 x 2.9 cm), each surmounted by a single osculum. Three of the 10 individuals of T.
Each tall mound in the unusual form is surmounted by a single osculum, whereas oscula in T.
Large specimens are clusters of tall volcano-shaped mounds, each mound surmounted by a single osculum; smaller specimens consist of a single tall, narrow, volcano-shaped mound rising from a wider base.
The calcareous sponge Leucosolenia laxa releases free-swimming coeloblastulae through the osculum with the excurrent water.
It has a large choanocyte chamber, or gastral cavity, with an osculum. Its body wall is very thin and transparent, hence the characteristic triradiate spicules are clearly visible.
When specimens of these sponges were bisected transversely, both halves could develop a complete new animal with the same polarity, from osculum to base, as the original (Tuzet and Paris, 1963).
Furthermore, 3 months after the beginning of the experiment, the half-cores with lower ectosome were covered by a collagenous, non-cellularized layer that remained white and formed no osculum; the half-cores with the upper ectosome produced a new oscule in 12-15 weeks and showed a normal pinacoderm periorated by pores.
ehrenbergi has many small excurrent canals that are accommodated along a central larger canal, leading to the osculum
