Clathria toxistricta

Clathria toxistricta, also known as Clathria toxistricta, is a species of sea sponge in the family Microcionidae. It was described by Émile Topsent in 1925.
It is described by Lévi, 1960 as follows: Red, plate-like sponge, approximately one centimeter thick, with a reticulated framework of multi-spiculated fibers and unispiculated secondary fibers.
Spicules:
Primary acanthostyles, slightly curved, often smooth, with a barely marked base: 145-245 μm x 6-10 μm.
Accessory acanthostyles, conical and straight with small spines more abundant in the distal half: 80-115 μm x 6 μm.
Auxiliary subtylostrongyles, slightly curved, smooth, few in number: 210-250 μm x 1.5-2 μm.
Palmate isochelae, few in number.
Toxas of fairly uniform size: 340-400 μm, rarely shorter: 110-220 μm, with very reduced central flexion.
Distribution: Naples.
