Desirable Nudibranch


The DESIRABLE NUDIBRANCH, of the family Flabellinidae, is a very tiny nudibranch found in clear waters with moderate currents.  The cerata tips are bright white in hawaiian species, unlike other species around the world that are cream-colored.  


They are armed with stinging capsules obtained second-hand from the food (hydroids) it feeds on.  Its scientific name, exopata, means "much desired" referring to its beautiful appearance.

Stocky Hawkfish


The STOCKY HAWKFISH (called po'opa'a) is typically found in shallow water perched atop exposed rocky areas or coral.  It will wedge its pectoral fins into cracks in order to stabilize itself during strong currents.  Its body is mottled blues, greens, and reds and has large white blotches along its sides.  The Hawaiian species tend to have more colorful head markings than species in other parts of the world.

Bigfin Squid


The BIGFIN SQUID (called muhe'e) is one of the few squid commonly found around coral reefs in shallow waters just offshore.  






They can be seen in small groups, hovering over the coral, resting during the day and feeding at night.  Like all squid, they have 8 arms and 2 longer tentacles, which are normally retracted and hidden.  They use these longer tentacles to reach out and capture prey. 









This squid is unique because of its 2 expanded fins forming an oval, which extends the length of the mantle.  It swims both forward and backwards with these fins, but is able to propel itself backwards much faster.  













They mature in approximately 100 days, and only have a lifespan of 9-10 months.
