The Kraken as seen in-game.

Krakens are passive NPCs unless the player mines crystal, an ore found at the lowest sea level. The kraken, usually in a swarm of 4 or 5, once provoked, will chase the player, causing damage every rougly 6-8 seconds.

The other way to provoke a swarm of krakens is to shoot one of them.

The Kraken currently has the most amount of HP out of any of the hostile NPCs, the most health belonging to the passive whale.
