There are some really weird-looking fish in the sea. And I do mean actual fish.

The folks over at The Fisheries Blog did a run-through of the "Top 10 Weirdest Things Found on a Fish's Head," and boy, are there some doozies. Some of the best include the "electrosensitve rostrum," found on goblin sharks and paddlefish. They look like the fish grew a Pinocchio nose, but are actually organs that are highly sensitive to electrical pulses — they can even sense the muscle twitch of a single tiny plankton! Equally as weird-looking are the "nuchal humps" found on male cichlid fishes that look like the fish bumped its noggin, but it may be used as a sexual display or for fat storage.
