Northern Kelp Crab
The Northern Kelp Crab (Pugettia producta) is commonly found in local tide pools during low tide. Their coloring depends on the type of food they consume. They’re primarily nocturnal and their diet mostly consists of kelp. Their favorites include bull kelp, sea cabbage, and rockweed. If eating green kelp, they tend to be green. If eating red, they tend to be red and so on and so forth. Because they take on the color of the surrounding kelp from their diet, they have a natural camouflage which helps to provide protection against predators.
Kelp crabs fall into the Family Epialdida, a group called masking crabs that like to attach algae and kelp to their shells to help with camouflage. Though kelp crabs mostly like to maintain a smooth shell for easier movement, they can occasionally be found attaching kelp and algae to their shells not as a mask but as a way to store food for later. Keep an eye out for these characters next time you’re in the tide pools!
Have you ever snorkeled in our local rivers? There are many beautiful creatures to be found. Featured is a Crayfish, also known as a Crawdad. They’re freshwater crustaceans resembling small lobsters. Though Crayfish can be found in a variety of locations around the world, North America has the greatest diversity with over 330 species.

California Newt, Cute AND Deadly
The California Newt (Taricha torosa) is a species endemic to California. Adults can reach 5 to 8 inches in length. Their skin produces a potent neurotoxin that is hundreds of times more toxic than cyanide, but is only harmful if ingested. Due to their toxicity they have very few natural predators. Garter snakes are their most common predator and some species have developed a genetic resistance to their toxins. The California Newt’s diet mostly consists of earthworms, snails, slugs, woodlice, bloodworms, mosquito larvae, crickets and other invertebrates.
