As long as you’re not a Crown of Thrones starfish, you should be fine.

Cone Snails are the venomous type of sea snail in the genus Conidae, with a radular tooth that injects neurotoxic venom. Conch snails are from Strombidae and are not poisonous, being primarily herbivorous.

However, the Giant Triton Conch snail is an exception and is an active predator that eats starfish and other marine invertebrates.
