Unfortunately, if they have, you have been misinformed.  So, does this mean that there is another plant that grows faster than giant kelp? Or was giant kelp never the fastest growing plant? Maybe your informant meant to say that giant kelp is …Read More »

    Hydro-Powered Holothurians: California Sea Cucumbers

    During a late afternoon dive several years ago in Fiji, I came across a sea cucumber (Bohadschia graeffei) that was upright and swaying like a cobra dancing to a snake charmer’s tune.

    Strange things happen in Northern California during springtime. Campgrounds and motels that were unoccupied most of the winter are now sold out. Coastal roads that were once empty are bustling with traffic. Large numbers of employees are mysteriously absent from their jobs. A case for the X-Files? No, it’s simply the beginning of abalone season. The red abalone is the …Read More »

    Seeing Spots: Studying the Two-Spot Octopus

    While two-spot octopuses are not uncommon in Southern California waters, they are usually found tucked away in a crevice. Thus, when I came across one sitting quietly on top of a ledge, I took a photo. I expected the animal to flee when my strobe flashed but it did not. I took another photo and ventured closer. That’s when I …Read More »
