i think scylla is not a hydra because in mythology it never points out that if you chop off her head it grows back. Plus there are theories that scylla was once a beutiful gilf that was turned into a monster.
Scylla and Charybdis, Cerberus, Medusa(and the other Gorgons), and the Hydra come to mind...
It's called a hydra. Scylla and Medusa are quite interesting too.
Poseidon was the Olympian god of the sea. There are numerous other, minor water gods such as Asopus (Ασωπός).
There is Scylla, Charybdis, Circe, Polyphemus, two bronze rams, Stymphalian birds, the Hydra, the Sirens, and plenty more.
