    Getting to Know Our Neighbors –The Blue Shark and Shortfin Mako Shark

    Marine researchers estimate that at least 34 species of sharks have been recorded off the Pacific Coast of North America. Some of them are rarely seen, and some species that were once commonly seen have, in recent years, become scarce due to overfishing.

    Cleverly Designed: About the Bat Ray, Pacific Electric Ray and Thornback Ray

    My success at photographing rays has hinged on chance. The ray(s) and I have been surprised to see each other and I somehow managed to take one or more photos before it (or they) departed.

    Since sea otters rarely spend any time on land most people will never see the lower part of them, which is usually underwater.
