Discussion

  • Weight at birth is guessed from Sterechinus which has Wd0 of 0.5 mug

Facts

  • The polychaete worm, Adyte assimilis and the copepod Pseudoanthessius liber are often found living as commensals among its spines and the parasitic copepod, Asterocheres echinola, often infests its gut (Ref: Wiki)
