Sea Dragon10

A ship with this keyword printed on its deckplate card is a sea creature. A sea dragon has a base move of D, meaning that it has unlimited movement. It ignores all terrain, islands, and ships when moving, but cannot end any movement overlapping a ship. When a sea dragon is given a shoot action, you may choose whether that action is a normal shoot action or a swoop attack (it cannot perform both with a single action). A swoop attack allows the sea dragon to attack any one target (including submerged ships) within L+L of its base. Roll a d6; on a roll of 4 or higher the swoop attack is successful and it eliminates up to two masts on the target. After resolving the swoop attack, place the sea dragon as close as possible to the target without touching the target.

Sea Monster2

A ship with this keyword printed on its deckplate card is a sea creature. At the beginning of your turn, decide if the sea monster is submerged or on the surface. If submerged, a sea monster can only move; it cannot shoot or be shot at, and it cannot dock or touch other ships. If a sea monster is on the surface, it may move or shoot like a normal ship. It may ram opposing ships (the rammed ship becomes pinned instead of the sea monster) and it may board. After winning a boarding action the sea monster may eliminate a crew or steal a treasure (if cargo space permits), but it cannot capture crew and if it takes a unique treasure that treasure is eliminated.

Crew Killing2

Once per turn when this ship hits an enemy ship, also eliminate one crew from that ship.
