Kina

Kina, SEA URCHIN, OR SEA EGG (EVECHINUS CHLOROTICUS)

The Kina is a round shelled animal covered in spikes. Divers should be wary not rest or press against a Kina as it can puncture and cause injury. They are herbivores and graze on algae covered reefs. Often Kina have eaten away all plant life on a particular piece of reef known as Kina barrens. They fall prey to many other invertebrates including the eleven armed seastar and crayfish. Large aggregations can be found on the off shores reefs such as Moeraki where they have cleared certain areas of algae.

Diameters of up to 20cm have been recorded.
