| Summary: | Plakina atka n.sp. Material: holotype: 62203B1, collected by Dave Carlile south of Atka Island (51°55`1.4``N, 175° 17`35.5``W) at 118 m depth. The holotype is deposited at the Senckenberg Museum, Frankfurt/Main, Germany under the registration number SMF 10324. Description: In life it is a pink to reddishbrown coloured sponge (Fig. 5). The sponge is light brown in ethanol. It is similar in growth form to Plakina tanaga n. sp. but with a slightly less convoluted surface and a different color. Single strands of the sponge have a smooth surface which is not microtuberculate like Plakina tanaga n.sp. The material consists of a single specimen encrusting a cobble. Thickness of encrustations is 0.3–0.8 cm. Consistency is more soft than P. tanaga and elastic. The specimen has an ectosomal dense spicule crust, averaging 100 µm in thickness. The choanosome is somewhat less densely packed with spicules. Spicules are vaguely arranged in tracts of varying orientation and with many spicules in between.
