A creature constricted by a lusca's tentacles is exposed to its deadly venom.
As a full-round action, a lusca can attempt to use four of its tentacles to grapple a ship of its size or smaller by making a combat maneuver check opposed by the ship's captain's Profession (sailor) check; the lusca receives a cumulative +4 bonus on the check for each size category smaller than Gargantuan the ship is. If the lusca grapples the ship, it holds the ship motionless; it can attack targets anywhere on or within the ship with its tentacles, but can't attack foes at all with its shark heads. Each round it maintains its hold on the ship, it automatically deals bite damage to the ship's hull.
A lusca does not gain the grappled condition if it grapples a foe with its tentacles.
