What animal did poesiden give?

It seems you're asking about "Poesiden," which is likely a misspelling of "Poseidon," the Greek god of the sea.

Poseidon is usually depicted with a trident, not giving away animals. He is often associated with horses, as he is said to have created the first horses.

However, if you have a specific myth or story in mind, please provide more context so I can help you understand the animal given.
