Sea Otters are about four feet long and weigh an average of 65 pounds for males and 45 pounds for females. They’ve got strong canines and strong molars to tear and crush their food. Their lung capacity is 2.5 times the size of land mammals of the same size. They have good eyesight and use their whiskers to sense vibrations in the water. They’re known for the use of tools when eating. Because they love mollusks, sea otters will use rocks as hammers and anvils to help open the shells. Because they have no blubber, they must eat 25% of their body weight in food to maintain their high metabolism. Grooming is important as it forces air bubbles into their fur that acts as insulation

A large, dark-backed gull of the Pacific Coast, the Western Gull is seldom found far from the ocean.

Red sea urchins (Strongylocentrotus franciscanus) are colorful creatures, varying between a uniform red and dark burgundy, that crawl slowly over the sea bottom, using their spines as stilts. They scrape off and tear up plant material from the sea floor, aided by a mouth armed with special jaws situated on the bottom surface of the animal.

Sea urchins belong to the marine invertebrate group called echinoderms or "spiny-skinned" animals. Close relatives of sea cucumbers and sea stars, they have spherical bodies, which are encased in a hard shell or "test", completely covered by many sharp spines. The species is large, with a maximum "test" diameter of over 18 cm and a maximum spine length of 8 cm.

Their preferred habitat is rocky ground with quantities of their food source of seaweeds and kelp. They avoid rocky areas exposed to extreme wave action and areas with sediments such as sand and mud.
