Slippery as an Eel
octopuses, sea otters, and whales, the sneakiest sea creature alongside the shark would be the moray eel. In nearly every form of media, eels are depicted as being sneaky creatures that have a propensity for tricking other sea creatures. It's a sure sign that they cannot be trusted. In other words, they're basically the oceanic version of snakes. Actual sea snakes are Seldom-Seen Species, probably because they're far less intimidating-looking than moray eels. Not to be confused with Psycho Electric Eel.

- Flotsam and Jetsam from The Little Mermaid are a prime example of this trope.
