spell negates a porpoise's blindsight. A porpoise that loses its blindsight for any reason also loses its +4 racial bonus to Spot and Listen checks.
A porpoise can hold its breath for a number of rounds equal to 6 X its Constitution score before it risks drowning.
A porpoise has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. A porpoise 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.
