Clathrina lacunosa is a species of calcareous sponge from the British Isles. The species name means "having holes" and refers to the perforations found in the sides of the sponge. It is usually found on vertical solid surfaces at depths down to 220 m. It is distributed in the north-eastern Atlantic from the Arctic to the Mediterranean. It is a fairly common sponge but is often overlooked due to its small size.

Description

This is a distinctive sponge, globular on a long thin stem, resembling a tiny balloon on a string. It reaches a maximum length of 3 cm and is often much smaller than this. There is an osculum at the apex of the sponge. Sponge composed of an ovoid body of thin, tightly and regularly anastomosing tubes, and a solid peduncle without any choanoderm. Water-collecting tubes converge into one apical osculum. Colour white in ethanol and light beige when dried. Triactines from the clathroid body range from almost regular to parasagittal with straight actines. Close to the peduncle there are parasagittal spicules with the longest unpaired actine pointing towards the peduncle. The skeleton of the peduncle is composed of large diactines with a break on the middle, and parasagittal triactines with a very long unpaired actine and short paired actines. Irregular diactines of variable sizes are present at low numbers in the peduncle. All actines are cylindrical with slightly blunt to sharp points. [1]

<i>Clathrina coriacea</i> Species of sponge

Clathrina coriacea is a species of calcareous sponge belonging to the class Calcarea and family Clathrinidae. Species in the genus Clathrina are composed of calcium carbonate tube-like skeletons containing spicules. The sponge can be located in shallow waters widely distributed along North Atlantic coasts, as well as on other coasts.

Arturia dubia is a species of calcareous sponge in the genus Arturia from Australia. The species was first described as Leucosolenia dubia by Arthur Dendy in 1891. The name is derived from Dendy's uncertainty about the validity of the species, believing his specimens could, in fact, represent juvenile Leucosolenia cavata.

Clathrina jorunnae is a species of calcareous sponge from Norway. It is only known from Trondheimsfjord, its type locality, where it was dredged from depths of 25–250 m (82–820 ft). The specimen was attached to a bryozoan of the genus Reteporella. The species is named after Jorunn Berg, Hans Tore Rapp's grandmother, who introduced Rapp to marine animals.
