Asterias forbesi Asterias forbesi Asterias forbesi, commonly known as Forbes sea star, is a species of starfish in the family Asteriidae. It is found in shallow waters in the northwest Atlantic Ocean and the Caribbean Sea. "Asterias forbesi" usually has 5 arms but occasionally has 4 or 6. Like many starfish species, the upper surface is covered in blunt conical projections giving it a rough feel. Some of these are pedicellariae, minute pincers that can grip objects. The arms are plump, broad at the base and tapering to a blunt tip. This starfish grows to about in diameter with an arm length
Crown-of-thorns starfish damage includes a major section of the disk together with arms, the number of arms regenerating on the disk may be less than the number lost. Another hypothesis is the "aggregation hypothesis", whereby large aggregations of "A. planci" appear as apparent outbreaks because they have consumed all the adjacent coral. This seems to imply that there is apparently a dense population outbreak when there has already been a more diffuse population outbreak that has been dense enough to comprehensively prey on large areas of hard coral. Female crown-of-thorns starfish are very fecund. Based on the eggs in ovaries, 200, 300
