Combat

Yurians use their large claws in combat. The males of certain yurian tribes have one enlarged claw that deals 1d8 points of damage plus the creature's Strength bonus.

Limited Regeneration (Ex): Yurians can regrow lost body parts as part of their natural healing ability. If a yurian loses a limb or eyestalk, the lost part regrows as soon as the damage is healed by any means.

Skills: Yurians have a +4 racial bonus on Hide checks. They have a +8 racial bonus on any Swim check to perform some special action or avoid a hazard and can always choose to take 10 on Swim checks, even if distracted or endangered.

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.
