Improved Grab (Ex): To use this ability, the kraken must hit an opponent of up to Huge size with an arm or tentacle attack. If it gets a hold, it can constrict.

Constrict (Ex): A kraken deals automatic arm or tentacle damage with a successful grapple check against Huge or smaller creatures.

Jet (Ex): A kraken can jet backward once per round as a double move action, at a speed of 280 feet.

Ink Cloud (Ex): A kraken can emit a cloud of jet-black ink 80 feet high by 80 feet wide by 120 feet long once per minute as a free action. The cloud provides total concealment, which the kraken normally uses to escape a losing fight. Creatures within the cloud suffer the effects of total darkness.

Spell-Like Abilities: 1/day - control weather, control winds, dominate animal, and resist elements. These abilities are as the spells cast by a 9th-level druid (save DC 15 + spell level).

Krakens strike their opponents with their barbed tentacles, then grab and crush with their arms or drag victims into their huge jaws.

Aquatic Subtype

Creatures with the aquatic subtype always have swim speeds and thus can move in water without making Swim checks. An aquatic creature can breathe underwater. It cannot also breathe air unless it has the amphibious special quality.
