Sealife: Large Yellowmargin Moray ("Franz"), Slipper Lobster, Coral, U'u's, Cowrie Shells, Anemones

A quarter mile off Lahilahi Point is a ledge at 50 feet, where boats tie off the mooring. The top of the ledge has a slight coral growth and a few tropicals, but it houses an 80 foot wide cavern that cuts 40 feet into the formation, and is open-ended seaward. The ceiling of Ulua Cave is encrusted with orange cup corals and pockmarked with pukas that yield discoveries of nudibranches, anemones and a large variety of crustaceans.

Although the cavern has lots of available light, bring a Dive Light with you (available from us). Tropicals seem to view the world in a topsy turvy manner as they patrol the cave's ceiling swimming upside down. The cave bottoms out to 80 feet outside the formation. One of the highlights here is reputedly the largest yellowmargin moray eel on the Wai'anae Coast, named "Franz". He shares his home, at the left side of the cave's entrance, with an unlikely companion - a slipper lobster. Do not feed here - two to three intremediate yellowmargins get aggressive at even the thought of food !
