Schmidt, 1870

Species Overview

Tedania (Tedania) suctoria Schmidt (1870) is a yellowish massive species, occasionally somewhat branching. The surface is covered in low papillae. It is a northern deep water species.

Taxonomic Description

Colour: Yellow or yellowish white in alcohol.
Shape, size, surface and consistency: (Tedania suctoria Ldbck) (Tedania suctoria Ldbck2) Massively encrusting, more or less roundish and lumpy; it may form lobes and branches, compressed, club-shaped. Size up to 9 cm in length, up to 3 cm in thickness. Surface is densely covered with conical papillae of up to 4 mm in length (Tedania suctoria papillas). Consistency rather firm, somewhat elastic.
Spicules: (Tedania suctoria spics) Megascleres: ectosomal tylotes, entirely smooth including the tyles: 250-470 x 3-6 µm; choanosomal styles, smooth, somewhat curved: 300-680 x 7-14 µm.
Microscleres: Onychaetes, inequiended, spined, possibly in two size categories: 55-500 µm.
Skeleton: Ectosomal: bundles of tylotes reach the surface membrane and fan out. Choanosomal: an irregular isotropic reticulation of spicule bundles and individual spicules, bound at the nodes by some spongin.
Ecology: 10-200 m
Distribution: Iceland, Norway, Faroes, Azores, Arctic.
Etymology: suctor (Latin) = sucking device, presumably referring to the conical papillae.
Type specimen information: The type is in the Copenhagen Museum, with a type slide in the Natural History Museum (BMNH 1870:5:3:104).

Remarks

This deep water species differs from the other species in the area (which are all shallow-water dwellers) by the papillate surface and symmetrical smooth tylotes.
