This was only our second trip to Morro Bay, but it already feels like home. The North T-Pier harbors an amazing array of marine life, including a seasonal parade of dozens (I think its fair to say) of species of nudibranch. Ken Bondy and Gary Powell have been diving, photographing, and documenting the marine life of Morro Bay for over 20 years. Their outstanding website captures the magic of the T-Pier and provides info about diving there: Morro Bay Underwater Home Page
Kevin Lee drove up in the middle of the night to join us for an early morning dive and get a crack at this fabled nudi site. Timing is everything here. As tide funnels through the bay, impressive, even ripping current restricts diving to a short interval at high tide.
Each day, Kevin made 2-hour-plus dives and found a greater variety of marine species than Phil and I put together. Moreover, Phil dubbed Kevin Nudi Master, and he really is, finding 17 different species of nudi, 3 of which were new to him! Check out the T-shirt.

My impression is that the uncommon is common at the North T-Pier. One night, we watched commercial fisherman hauling in nets full of hagfish that they trapped at 300 fsw using pig head bait. The hagfish were bound for Korea, as live fish product.
According to Milton Loves Certainly More Than You Want to Know About The Fishes of The Pacific Coast. A Postmodern Experience, this is one cool eel-like fish. Theyre blind, with neither jaws nor vertebrae. That stringy goop is a mucous-like slime that hagfish produce when agitated. One set of glands produces the mucous and another set of glands produce microfilaments that transform the mucous into a more elastic substance. Why produce slime? Its been proposed that the slime may serve to impair the gills of predator fish. Fishermen rake it out of the tanks by the handfuls.
Besides low vis, the first thing that struck me about diving under the pier was the number of bivalves. Clams everywhere, opening and closing their siphons to beat the band.
Pacific Gaper Clam, Tresus nuttalli
I would not be exaggerating if I were to say that nudibranchs were as thick as flies - sometimes bumping into each other. Phil and Kevin occasionally got two uncommon-down-here species in the same frame.
Janolus barbarensis and Hermissenda crassicornis
Acanthodoris lutea is common there.
Aeolidia papillosa feeds on anemones.
Both color variants of Polycera atra were present, some laying eggs.
Polycera hedgpethi
This approx. 5 fish was buried under sand before I disturbed it. Clinton Bauder kindly IDd it as a Pacific staghorn sculpin, Leptocottus armatus. This fish fooled me! I didnt recognize it in the fish ID book because it can change color/markings to blend in with the substrate.
This is an invertebrate-lovers paradise. Bryozoans abound in spectacular array, both in chunks on the seafloor and on the pilings. Totally cool and intriguing amphipod species appear in nearly every bryozoan photo, but theyre too small to resolve with a 60mm lens.
Kevin found this small, cryptic nudi, Adalaria jannae, which blends in perfectly with its Membranipora bryozoan food source. Not only are there 3 of them in this photo, but so are their eggs. Bonanza!
A closer look at the two Adalaria jannae.
We could spend a week diving here, but Im not sure if that would be enough time.
