Sea Lions

Sea lions are also common and Isla San Pedro and other islands are a sanctuary for these creatures. Divers and snorkelers are often treated to underwater displays by the sea lions. Use caution around the big bulls-when they bark, back off.

Sea Birds

If you are a bird watcher, San Carlos is a joy. Mexican Brown pelicans cruise the shoreline in large numbers and watching them go after a school of baitfish is great fun. There are numerous terns, gulls and other sea birds and osprey (fish hawks) are common. Anglers know to "follow the birds" offshore and high flying frigate birds will generally show you where the game fish are.

Orca and Catch 22

This photo is very real.  This large male Orca decided it was time for a jacuzzi like bath from the prop wash on Catch 22. The animal is nearly the same size as the 34 foot sport fisherman.  Photo by Fernando Almada, Catch 22 Sport Fishing
