No grunion observed. However, it was a lovely, warm evening chatting it up with other "official" grunion greeters - Diane, Bonnie, and Susanna. They're wonderful ladies! I feel badly Susanna has yet to see a single grunion during this whole season. Bonnie went out the second night during the last new moon cycle, the only time we did not. She saw a couple of grunion. For actual grunion pics this season, see my "grunion greeting" tagged posts for June 7, May 25, and May 24th.
We arrived at 10:10pm, a little before the official requested time and high tide. It wasn't much of a high tide since the biggest waves only came up between the 8th & 9th parking meters. There were ~5 people on the beach wading in the waters and simply enjoying themselves when we arrived. Much to my surprise, there were no mackerel fishermen on the wharf. A handful of the usual nighttime fisherman were tossing their lighted bobs from the pier (I had to go ask, b/c we were coming up with wild ideas of how the chemical lights somehow attracted fish).
My husband and I walked down the beach to the cement structure between 11:10 and 11:25pm, to no avail. We found a partially eaten skate on the shore (pictured above). A certain amount of debate carried on whether it was a ray or not, but thanks to Bonnie's expertise, we finally concluded it was a skate based on the tail. I loved the human-like face on the underside.
There was extra lighting on the beach sands thanks to bright lights from the Bronco World Series just down the street. A small group of western and other gulls showed up on the berm about a half hour before we left. They seemed to be hunting but not for grunion.
We left at 12:20am. Phooey!
ps 05/13/10 - Thanks to seeing a leopard shark today and looking around online, I figured out the picture above is a thornback skate (Raja clavata). Are skates and rays the same?
psss 07/11/13 - After having seen another skate, I looked into this some more and am fairly sure this is not a thornback skate since it doesn't appear to be found in the Pacific Ocean. Finding easily accessible online ID sites for marine animals is a challenge. Here's a good link describing the difference between skates and rays.
