Tag: Pin Cushion Starfish (Culcita Novaeguineae)

The Pin-Cushion Starfish (Culcita Novaeguineae) is a strangely shaped and reasonably common member of the starfish found in local waters.

Growing to a maximum diameter of around 30cm, this species may be found in a large variety of colours, ranging from gray, brown, red, purple, or a combination of these.

Adults is easily recognised by their inflated cushion-like appearance, although juveniles are much more flattened.

Although difficult to distinguish, there are five arms and the skin is covered with numerous, bumpy protrusions.

The Pin Cushion Starfish feeds mainly on algae, detritus and certain species of coral polyps. It moves around slowly on very short legs and its movement may be hampered by its relatively inflexible body structure.

NOTE: There is a lot of misleading information and possible mis-identification between the Pin-Cushion Starfish (Culcita Novaeguineae) and the Indian Cushion Star (Culcita Schmideliana).

If anyone can positively identify the species featured here, it would be greatly appreciated.
