description
(Fig. 6 A) Synonymy. Caulophacus schulzei Wilson, 1904, 43; Lendenfeld, 1915, 48; Lévi, 1964, 100; Koltun, 1967, 116; Beaulieu, 1998, 50; 2001, 808.
description
Description. Only a moderate-size margin of the specimen on the left of Figure 6 A was collected for determination. The specimen is stalked and attached to a rock outcrop. The body is a wide shallow cup with undulated margin. Attachment of stalk to the body was not recorded in the video. The body is 60.5 cm in diameter as calculate from 10 cm laser spacing indicated at left of the in situ image.
discussion
Remarks. Spicules of the collected 1.3 cm thick wall fragment agree with both Wilson’s (1904) original description and the review of the cotype specimen of Caulophacus schulzei from the Gulf of Panama. In all reports, the species is encountered in large numbers of specimens.
distribution
Distribution. The species is known to have a very wide distribution from the Tasman Sea, N. Peru, Ecuador, Gulf of Panama, Central California and the Bering Sea from 3183 - 4510 m depths. The present report is a range extension to Northern California and provides the first in situ image of the species.
