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.Dados curados por Daniela Paz Villegas Del Rio em 09/07/2025 para atividade avaliativaapplication/pdfapplication/pdfCopyright (c) 2012 PRABHU kOLANDHASAMY, Bragadeeswaran Subramanianinfo:eu-repo/semantics/article
