Hold Breath (Ex): A sea lion can hold its breath for a number of rounds equal to 6 x its Constitution score before it risks drowning. For a typical sea lion, this is 72 rounds, or over 7 minutes.

Skills: A sea lion has a +8 racial bonus on any Swim check to perform a special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.

Sea lions possess a powerful and dangerous bite. They rarely attack humanoids in the water but are more than capable of chasing off landbound intruders who get too close.
