Descrição
Starfish Astropecten indicus was collected from bycatch landings at Mudasalodai fishing harbour, Tamil Nadu (India) in November 2011. Totally 134 specimens collected among three specimens (2,2%) have abnormally developed four and six arms. Normally, A. indicus has five arms and the deviation from pentamerism is a rare phenomenon in starfishes. The present observations suggest that deviations from pentamerism are not a heritable character but are a consequence of environmental perturbations on the metamorphosis of larvae and/or abnormal regeneration of arms.
