Pseudopterogorgia kallos

Brief description Pseudopterogorgia kallos is very close to the shrubby examples of P. bipinnata but can, in summary, be recognized by (1) the bushy habit of growth, with steeply ascending twigs not strictly in one plane and not always opposite (2) the scaphoids with the spaces between the crests of the convex side filled in except for the median constriction and (3) the short anthocodial rods with noticeably clubbed ends.
