Facts

  • dioecious, which means that each individual is either male or female (ref: Wiki)
  • length-weight: W in g = 0.0025 * (major radius length in mm)^2.22; becomes relatively more slender as it grows (ref: BaetGali2016)
  • In the study area it feeds mainly on the bivalves Glycymeris glycymeris and Callista chione, together with the gastropod Cyclope neritea between 5 and 30 m depth and almost exclusively on the bivalve Timoclea ovata between 50 and 200 m depth (ref: BaetGali2016)

Discussion

  • Because this species changes shape during growth, arm length was converted to volumetric length
