Likely illegal gill net debris.
Gill netting is illegal in the US and its waters. Given the choice of float material and a general idea of current direction this is likely from a fisherman in Mexico. Stuff like this gets hung up on something underwater, or gets tossed overboard and becomes a potential death sentence for sea turtles, fish, crustaceans. Microplastics enter the water from the net material breaking down. Given the size of the gooseneck barnacles here I’d bet this has been in the water a couple years or more.
If i stood at this bundle of netting with a rock in my hand, faced down the beach and threw the rock, it would land right next to another net disaster just like this one. I could walk to the rock, pick it up, throw it, and it would land right next to another net disaster. All the way down the beach. I participate in yearly beach cleanups, I pack garbage bags w me and carry out multiple bags full each visit. And it never ends. Its quite depressing sometimes. Plastic is a fucking cancer.
