Eudendrium capillare Alder 1856

Description

Eudendrium capillare Alder, 1856

(fig. 2K–L)

Eudendrium capillare Alder, 1856: 355, pl. 12 figs 9–12.—Millard, 1975: 82, fig. 27E–J.— Calder, 1988b: 41, figs 30– 32.—Hirohito, 1988: 77, figs 24G–H, 25.— Marques et al., 2000: 88, figs 28–34.— Schuchert, 2001a: 27, fig. 16.

Material examined. Stn. 7: 25.03.2008 —a small, sterile colony composed of several unbranched or sparingly branched stems, up to 4 mm high, on alga.

Type locality. Embleton Bay, Northumberland, Great Britain.

Remarks. The identification of this small, sterile Eudendrium is based on the presence of a single type of nematocysts (heterotrichous microbasic euryteles) in the hydranth. The dimensions of undischarged capsules, (7.0–8.1) × (3.0–3.4) µm, are very similar to those reported by Calder (1988b) for E. capillare from Bermuda, i.e. (7.1–8.0) × (3.0–3.2) µm. For a recent description of this species, see Calder (1988b). Additional notes on the structure of gonophores are given by Marques et al. (2000).

Distribution. Reliable records, based on identification of the nematocyst complement, are from Europe, the Mediterranean, Bermuda, South Africa, and Greenland (Schuchert 2001a).
