Saw 7 or 8 healthy looking sunflower stars, one probably 50cm in diameter. Also one of the largest ruby octos Ive ever seen, flattened against the clay wall pretending to be part of it.
Dive report for 5/25/26
- Visibility
- A snowy 15-20 feet, 5 feet in the shallows
1st dive 1040, 2nd dive 1220, 50F
strong current near the shoreline in the shallows until about 15ft when the steeper slope starts. Had to pull ourselves back on the 1st dive and still got swept away near the surface about 150ft towards the boat launch.
First time at this site, found the tree stump with hundreds of copper rockfish at 70ft, from baby finger size all the way to large adults. 1 red octo, 1 gpo, 1 juvenile wolf eel, 1 striped nudi, lots of flat fish and opalescent nudi, 2 schools of tubesnout, a few gunnels, a few good size dungeness crab, and at least 2 dozens of sunflower sea star (mostly small ones 4-5 inch, two larger ones over 12 inches)
no pictures this time; I'll report the sightings and remember to get some photos next time we dive there!
Great - he just told me he particularly would like photos that include the madrepore (the whitish spot near the center of the body).
Can you email [email protected] about the sunflower star sightings, with pictures if you have any? I saw 3 smallish ones there a couple of weeks ago and notified him. That raised the question of whether the Muk clay wall is a previously unrecognized sunflower star hotspot and your sightings make that significantly more likely, I think. Thanks!
