One of my most favorite animals of all time is the Glaucus Antlaticus sea slug.

They are absolutely gloriously beautiful, and look like little celestial angels. So, I made one! 8D

In proper sea slug fashion, she is both blind and deaf, lacking ears and eyes. However, she does have a very keen sense of touch, being able to detect someone in her waters from several hundred feet away. She understands most dialects of sign language, and communicates as such. her name is very complex, using most of her tentacles, so most people just call her Cassandra. She is also very gooey, secreting a neuro-toxin to keep predators (of all kinds) at bay. It will paralyze you, leaving you motionless in her water until you drown or she takes pity and drags you to shore. Despite being crippled however, she is very curious and will explore anything that moves, and several things that don't. Including you.
