Marbled Blenny and Helmet Urchins
Entomacrodus marmoratus or the Marbled Blenny, with Shingle or Helmet urchins (Ha'Uke'Uke), Magic Island, Hawaii. These amazing little Hawaiian blennies come up out of the water as the waves wash over shoreline rocks. They sit on these rocks where they graze on algae, ever keeping a watchful eye for threats such as stray humans or the occasional bird or crab. Their eyesight appears to be quite good, even out of water. When threatened,do a quick snap of their tail, possibly with a bit of a wiggle to get to the edge of the rock, to escape back into the ocean.
The local fishermen will sometimes catch these little blennies to use as live bait for larger fish such as Ulua (Jacks) and Baracuda.
Also shown are a group of Shingle or Helmet urchins, Colobocentrotus atratus. These are called Ha 'uke 'uke in Hawaiian and, while edible,are not commercially harvested. They are usually found out of water in the splash zone clinging to large rocks.
