Color: The background of the body is a reddish brown, and the entire body is covered by many, small light spots located on the centers of each scale. The posterior half is marked by a longitudinal white stripe along the upper side. The prominent "U" marking behind the eye will always serve to identify it. (See photos)Size: Five to Six inches in length. Habitat: The Arc-Eye Hawkish is sedentary, spending most of its time perched upon a rock or coral head, making quick short dashes for food and returning to a rock or coral head again.
Distribution: Hawaii southward to Central Polynesia, westward through Micronesia and Melanesia, through East Indies, Indian Ocean, Africa and the Red Sea.(Shot taken by Jim Robinson with a Nikon RS with a 50 mm macro lens, using Fuji 100 Provia film an SB104 strob.

From the end of the tunnel heading north, you will come to the entrance of Skull Cave, it appears to be an amphitheater with large benches for the audience in the cave. The front of the cave has two large openings "the eyes" and the support between them is the "nose." The walls sport various growths of algae, yellow-white sponges and the ceiling is covered with Orange Cup Coral. The cave is alive with marine life, from countless Red Big Eyes (Squirrel Fish) and if you look around there may be a Puffer Fish or a large Porcupine Fish hidden in a shadow on the floor of the cave.
Continuing north from Skull Cave, there is a smaller cave that often has a resident white tip shark resting from his night of feeding on small shore line reef fish. The cave will only support two on lookers; we would not like disturbing his rest would we? There are many other interesting marine life forms that can be found inhabiting the coral heads in the surrounding area: large octopus, eels and schools of Goat Fish. As a warning, this dive site can be very dangerous during southerly swells and high surf condition.
