Overview

Comprehensive Description

Description

 Bugula flabellata forms an erect, densely tufted, branched colony about 2-5 cm in height and is a buff colour when living, grey when dried. The branches are broad, flat and wedge-shaped, and composed of rows of four or more zooids, somewhat circularly disposed. Individual zooids are rectangular in shape and 0.5-0.8 x 0.2 mm. Zooids at the margin of the branches bear 3 spines on the outer distal corner and 2 on the inner distal corner. Inner zooids bear 2 spines on each distal corner. The front of the zooid is almost entirely membranous. The polypide has 14 tentacles. Avicularia are present on inner and marginal zooids, being larger on the latter, with the beak hooked rectangularly. Brood chambers (ooecia) are sub-globular and conspicuous. Colonies are attached to the substratum by extensions of the basal zooids termed rhizoids. Yellow embryos are present from early May to October. The newly settled larvae form ancestrula with 3 proximal spines and 3 spines on each distal angle.

General Description

Bugula flabellata is an erect bryozoan that forms low dense tufts, between 2 – 3 cm in height. The colonies are made up of a number of fan-shaped shoots that are dichotomously divided into flat wedge-shaped branches, broadening at the tip. The branches are arranged in a somewhat circular manner and often slightly convoluted. When living the colony is of a buffish colour, but turns grey when dried.

The species almost invariably attaches to other bryozoans. Even when it is apparently growing on rock or shell, closer examination usually shows the exact site of attachment to be some species of encrusting cheilostomate bryozoan. Bryozoan species commonly supporting colonies of B. flabellata include Porella concinna, Schizomavella auriculata, Schizomavella linearis, Cellepora pumicosa, fronds of Flustra foliacea and lobes of Alcyonidium diaphanum. Small modified zooids which resemble rootlets (rhizoids) are used to attach to the colony to the substrate. The species often occurs as a co-dominant with Chartella papyracea in communities colonizing vertical shaded, sublittoral rock surfaces in the Bristol Channel.

Bugula flabellata is relatively common on the lower intertidal area of rocky shores, extending down to shallow inshore waters. The species apparently has a wide geographic distribution and occurs throughout the North Sea and off all British coasts.
The species appears to be a successful fowler, and its arrival and spread has been recorded in New Zealand ports. On the east coast of America, Bugula simplex was long mistaken for Bugula flabellata.

Distribution

Haast altijd op andere Bryozoa, zelfs als ze schijnbaar groeien op rotsen of schelpen. Loppens (1906) vermeldt deze soort als algemeen op Flustra foliacea, stenen en schelpen en in de haven van Nieuwpoort sublitoraal op havenconstructies. De grote hoeveelheid materiaal op Flustra foliacea in het KBIN doet vermoeden dat deze soort in het begin van de 20ste eeuw veel algemener was dan nu. Recent in België op aangespoelde Flustra foliacea en plastic voorwerpen. Tijdens een campagne op de Hinderbanken in 2005 werd op slechts één plaats Bugula flabellata aangetroffen. De achteruitgang van Flustra ligt mogelijks aan de basis van een achteruitgang van Bugula flabellata. Bijzonder weinig waarnemingen uit Nederland: aangespoeld in Scheveningen op kurk (Lacourt, 1949), in september 2003 bij Callantsoog (de Ruijter, 2003b) en in augustus 2005 bij Egmond aan Zee (de Ruijter, 2006a).

Physical Description

Diagnostic Description

Description

Vormt een laag, dicht bosje van 2-3 cm hoog, van geelachtige kleur bij levende, maar grijs of bruin wordend bij droging. Takken breed, distaal het breedst, ietwat cirkelvormig gerangschikt. Zoïden in 3 tot 8 rijen, langwerpig, van gelijke breedte blijvend, het membraan neemt geheel of het grootste deel in van het frontaal oppervlak. Stekels 3:2 (2:2 op binnenste zoïden), van variabele grootte; deze op de marginale zoïden soms heel groot. Polypide met 14 tentakels. Avicularia aanwezig op zoïden van binnenste en marginale rijen, laatstgenoemde aanzienlijk groter; vastgehecht 1/3 tot halfweg naar beneden langs de zijkant; bek rechthoekig haakvormig. Broedkamers bijna bolvormig; embryo’s geel, van mei tot oktober. Ancestrula met 3 proximale stekels en 3 op elke distale hoek.

 Occurs on the lower shore and shallow sublittoral rocky shore. Usually attached to other bryozoan species such as Porella concinna, Schizomavella auriculata, Schizomavella linearis and Cellepora pumicosa, as well as the fronds of Flustra foliacea and the lobes of Alcyonidium diaphanum.
