Ascidiella aspersa is a species of solitary sea squirts native to the northeastern Atlantic, from the Mediterranean Sea to Norway. They possess oval bodies up to 50 to 130 mm (2.0 to 5.1 in) in length. Their branchial (or oral) siphons are conical and positioned at the top of the body. They possess six to eight lobes. The atrial siphons are located at the upper third of the side of the body and possess six lobes. The body is covered by a firm transparent test that is greyish to brown in color. The test often snag detritus that remain loosely attached to the animal. When expanded, at most 40 tentacles can be observed on the inside surface of the branchial wall. Both the openings of the branchial and atrial siphons possess lighter colored ridges on their rims. They may also be frilled at times. A. aspersa are attached to the substrates by the left side of their bodies. They can be found in dense groups of unfused individuals on hard surfaces like rocks. at depths of up to 90 m (300 ft).[2][3][4][5]
A. aspersa closely resemble Ciona intestinalis, but can be distinguished by their lack of yellow markings around their siphons.[2]

De ruwe zakpijp is meestal aan de zijkant vastgehecht. Als je ze uit het water tilt spuiten ze water uit; vandaar de bijnamen 'zeikers' en 'pissers'. Ze kunnen massaal aan de onderkant van boten zitten. Met de hogedrukspuit kun je er van af halen.

This species is solitary but commonly found in dense unfused aggregations. The body is ovoid in shape, up to 130mm long and usually attached to the substratum by the left side. The test or layer that encloses the body is firm to touch, thick, rough and gristly, and is greyish-black or brown in colour, often with attached detritus.

A tall solitary sea squirt usually found in clumps and attached by its base. The body is oval with a fluted oral siphon at the top and an upward-directed atrial siphon 1/3 of the way down the side of the body. The test is grey and semi-transparent, usually covered with lightly adhering detritus, filamentous algae, etc. There is a series of lighter marks around the edge of each siphon, and the large oral tentacles can easily be seen inside the oral siphon in expanded animals. Typical size 50-100mm. Ciona intestinalis always has yellow marks around the siphons, and is different in shape and consistency. Ascidia spp. have firmer tests. Ascidiella scabra is usually smaller and more squat, with both siphons more or less on a level.
