Overview

Comprehensive Description

General Description

Aetea anguina is a common bryozoan, present on all British coasts and occurring throughout the world, except in polar waters. The species ranges from the very lower intertidal zone, through the shallow subtidal, down to 50 m, and very rarely beyond this depth.

Aetea anguina colonises kelp holdfasts- most frequently species of Laminaria,- small red algae, hydroids (Hydrallmania, Sertularia) and erect bryozoans (Eucratea) A. anguina may also colonise stones and shells.

The colonies are composed of creeping stolons made up of tubular zooids, which rest against the substrate at the proximal end (closest to the colony origin), and rise into a free erect portion at the distal end. The adnate portion of the colony, parallel to the substrate, is branched and the colony is white in colour.

Distribution

In België op aangespoelde voorwerpen en riemwiervoetjes (De Blauwe, 2000b, 2000c, 2005, Vanhaelen et al., 2006). De oudste waarneming uit België is opgenomen in Westendorp (1843), op aangespoelde wieren in Blankenberge. Lacourt (1949) vermeldt het aanspoelen op kurk in Scheveningen. Bloklander vond deze soort op aangespoeld materiaal in Nederland in de herfst van 1947 (Bloklander & Leenhouts, 1948).

Physical Description

Diagnostic Description

Description

Kolonie wit, het vastgehechte deel vertakkend, een zoïdensteel opgericht van elke verwijding. De zoïdensteel is zwak maar duidelijk geringd bij doorlichting. Het distaal deel van de zoïde draagt een frontaal membraan die 1/4 tot 1/3 van de vrije lengte inneemt, breder dan de steel, spatelvormig, niet geringd. Steel gewoonlijk gebogen met het frontale membraan naar beneden gericht. Embryo’s worden gebroed in tere, verdwijnende broedzakken. Broedzakken zeldzaam.
