Rocktopi are large types of octopus and some of the most poisonous creatures in the world. Their tentacles can become up to 3 meters long and they aren't eaten by any creature because of their poison. They themselves are herbivores and survive on eating seaweed. Even though it's useless because they don't have to hunt or hide, rocktopi look just like rocks when not moving. This has led to many people stepping on them accidentally when the tides are low and getting poisoned, causing death. They live in the Sea of Kimzar.
