Temnodontosaurus

This massive beast resembles a reptilian porpoise, only on a grander scale. Its long beak is lined with sharp conical teeth, and its four fins are well-muscled. Most notable are its eyes, which are the size of dinner plates.

The average temnodontosaurus is 30 feet long. They are fast and intelligent creatures, with a well-developed social system. They have remarkably keen eyesight due
to the size of the eye- proportionately, the largest in the animal kingdom. Temnodontosaurs, like all icthyosaurs, never leave the water; unlike other aquatic reptiles, icthyosaurs give birth to their offspring alive. Temnodontosaurs feed on fish, squid and ammonites, and are harmless to humanoids, despite their size and strength, unless they are attacked first.

COMBAT
Temnodontosaurs are mobile opponents, darting in and out of their foes reach in order to deliver sharp, powerful bites.
Hold Breath (Ex): A temnodontosaurus can hold its breath for a number of rounds equal to 6x its Constitution score.
Skills: A temnodontosaurus receives a +8 racial bonus to all Spot checks. A temnodontosaurus 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.
