Brissopsis elongata Mortensen

Brissopsis elongata Mortensen, 1907:163, pi. 3: figs. 4, 14, 15, 19; pi. 4: figs. 1, 4, 13, 18; pi. 18: figs. 2, 15–17, 21, 28; pi. 19: figs. 12, 17. [See Chesher, 1968a:63, for synonymy, detailed description, and illustrations.]

This species occurs in mud fields with Paraster doederleini Chesher, Paraster cf. P. floridiensis, and Moira atropos (Lamarck). It is not common. We collected nine specimens, and it took approximately 20 minutes to find each one. They live buried 40–100 mm in the mud. Burrowing beneath the surface takes 10 minutes, faster than any of the other spatangoid species occurring with them. Observations of live B. elongata, in situ have never been published before, and photographs of it burying itself in its natural environment are on Plate 9: figures 4–6.

Brissopsis elongata has been previously reported from the South American coasts of Venezuela to Panama and from Puerto Rico at depths of 13–72 m (Chesher, 1968a:76).

Brissopsis elongata is a species of sea urchins of the family Brissidae. Their armour is covered with spines. Brissopsis elongata was first scientifically described in 1907 by Ole Theodor Jensen Mortensen.
