Just had four awesome dives on the Peace boat at San Miguel. Those were some of the colder dives I’ve made here with water temps in the upper 40’s. Though a bit on the painful side (Note to self: fix that dry suit), San Miguel delivered as usual. Never saw that many Lion’s Mane nudibranchs in one spot.
Those Lion’s Mane are pretty awesome not so little nudibranchs. First, they swim. None of the others really do that. But what really sets them apart it they way they eat. They have this huge head bulb that they can expand and use like a fishing net to filter the water for food. I have captured a video of this.
