There are so many sea otters off of the coast of Avila Beach that I can't remember exactly how many I saw. Anyone who doubts that otters are a keystone species need only go fishing up here to see first hand the relationship between otters and a healthy kelp forest, full of fish and other marine organisms. In order to get an understanding of just how rich a kelp forest is I went diving.

As you can see, a proliferation of kelp acts as a magnet for predators, a source of food, a nursery for juviniles, protective cover, and a home for many different creatures. By the way, this picture is actually from the main tank in Monterey Bay Aquarium, in case the way I posted this was misleading, heh. I have yet to dive this section of coastline.

My older sister, who volunteers at the aquarium, tells me the population of otters on the Pacific Coast is not doing too well right now, in general. A feline disease gets into sea water when people flush their kitty litter down the toilet instead of throwing it away, and otters contract this and die.

Another problem with otters is that they like to live where they grew up, so it is hard to reintroduce them into areas where they should do well. Otters that are dropped onto the Channel Islands have often swam all the way back across the channel, driven by their homing instinct to return to their points of origin to the frustruation of the marine biologist who worked so hard to put them there.

Here's a crop of a juvinile and an adult, chillin' by the kelp.

Snowy white islands look pretty, but tell a different tale when you're downwind. We were upwind, and even then the stench of guano was overpowering.
