Turtle weed

Chlorodesmis fastigiata
This algae is actually quite toxic and turtles don’t eat it. A few rabbitfish will eat it and a few nudibranchs (Elysia spp.) that can not only tolerate the toxin, but will store the toxin in their own skin to become toxic. Unfortunately there is a carnivorous nudibranch that can also tolerate the toxin and specialises in eating Elysia spp.
I think it should be called nudibranch weed.
