|~ Ichneutae's famous last words, before being killed by Scylla|
She is a sea monster looking like a multi-headed hydra. She guards the Bermuda Triangle, also known as the Sea of Monsters, along with Charybdis.
After Thalia's tree has been poisoned by Luke Castellan, Clarisse La Rue and Ichneutae are sent to Polyphemus's island in the Sea of Monsters to get the Golden Fleece, which has the power to heal anything. However, when they arrive they run into Scylla, who attacks their ship. Ichneutae tries to fight her, but Scylla manages to kill him. Clarisse eventually escapes her, unfortunately her ship gets swallowed by Charybdis shortly after.
