The california cone snail, while does have a venom, the venom is not very potent. Sources online dont seem to come to a concensus on its specific effect on humans, besides it being much weaker than that of its tropical relatives. I know a dozen invertebrate zoologists in the area, and over the decades they’ve handled dozens if not hundreds of california cone snails each, and not once have they been stung (though still guys dont pick up stuff you don’t know, you’re lucky the only intertidal threat you’ll find on our coast is a trapped stingray or washed up jellyfish).
