What marine life calls Coronado Islands home?

Many of the usual Southern California sea creatures can be found here, with a few major exceptions such as finescale triggerfish, elephant seals, and some pelagic fish species like skipjack tuna, mola mola, and yellowtail.

The main attraction here is diving with sea lions. Shortly after pupping season (spring and summer months), the friendly pups will blow bubbles in your face or even zoom by with their mouth open.

If you find yourself tired of the sea lion activity, try looking for some of the hidden reef creatures like two-spot octopus, moray eels, and scorpionfish, all of which can be found along the shallow reefs of Coronado Islands.
