Inferring the developmental basis of the sea star abnormality "double ambulacral groove" (Echinodermata: Asteroidea)

Very rarely a ray of a sea star is unusually wide and has two parallel ambulacral grooves that extend to a single tip. Such a ray has two terminal plates that are coalesced laterally. This abnormality is inferred to develop as a rare result of regeneration because it is recorded from a species with...
