Beautiful
The California sea hare is a mollusc, so it’s related to snails and clams. But its dinky little shell is inside the big, slippery body, so a sea hare can’t pull back into its shell for protection. It’s called a sea hare because it has two tentacles on its head that look like rabbit ears. Sea hares get to 30 pounds and 16 inches long, and you may have seen these godzillas in shallow water, munching on sea grass or seaweed. And if they eat red algae, the slugs can squirt out a big cloud of purple ink and escape from a fish eyeing them for its dinner.

The graceful manta ray is a stunning member of the devil ray family, if only for its sheer size. These large rays have a distinctive body shape with triangular pectoral 'wings' and paddle-like lobes extending in front of their mouths. They are generally dark on the upper surface, ranging from black to greyish-blue and brown, with pale undersides; individuals have a unique pattern of blotches and scars that can be used to identify them. The large, cavernous mouth is situated at the front of the body and contains 18 rows of teeth on the lower jaw.

Adult Yellow Tangs inhabit coral-rich areas of lagoon and seaward reefs from below the surge zone to about 46m and enthopelagic over rock at 1-81m. They occur singly or in loose groups and are mainly herbivorous, browsing on filamentous algae. Group spawning and pair-spawning by territorial males that court passing females were observed. Spawning activity occurs around the full moon indicating lunar periodicity and spawn in batches throughout the year. Presence of a venom gland could not be determined despite the presence of distinct anterolateral grooves; this may be due to the loss of venom glands in adults. A popular aquarium fish and the top marine fish export from Hawaii.
