About California Sea Otters

The California sea otter (Enhydra lutris nereis) is a keystone species that helps keep kelp forests healthy by eating sea urchins and other invertebrates. After a dramatic population crash in the early 1900s, conservation efforts have helped them rebound along the Central Coast, with notable viewing near Monterey, Moss Landing, and along the Monterey Bay coastline.

Otters have the densest fur in the animal kingdom and no blubber—so grooming is life or death! Their social groups are called “rafts,” and you’ll often spot pups riding on mom’s belly.

Playful Trivia

Pocket Rocks

Otters stash a favorite rock in a loose skin fold under the arm to crack open clams, snails, and urchins.

Fur Real

With up to a million hairs per square inch, their fur traps air for warmth—no wetsuit needed.

Raft Life

Groups of otters are called rafts. Moms often wrap pups in kelp to keep them from drifting.

Kelp Forest Guardians

By eating urchins, otters protect kelp forests, which store carbon and shelter marine life.

Snack Schedule

They eat ~25% of their body weight daily to fuel high metabolisms in chilly Pacific waters.

Tools of the Trade

Sea otters are among the few mammals that routinely use tools—shells and rocks—while floating on their backs.

How to See Sea Otters—Safely

In the Wild (Monterey Bay & Elkhorn Slough)

  • Stay at least 60 yards (55 m) away—more if pups are present. If an otter looks at you, vocalizes, or changes behavior, you’re too close.
  • Use binoculars or a long lens. Never chase or encircle otters with kayaks or SUPs.
  • Keep noise low; avoid sudden paddling bursts. Give nursing moms extra space.
  • Launch/land well away from resting rafts; pass parallel at a slow, steady pace.
  • Pack it in, pack it out: leave kelp, shells, and haul-out areas undisturbed.

At Monterey Bay Aquarium

  • Enjoy close views of rescued otters and pups in professional care.
  • Follow staff guidance; flash photography and banging on glass stress animals.
  • Check the daily schedule for otter feedings and talks.
  • Consider joining as a member—your support funds rehabilitation and research.

Reminder: Harassing marine mammals is prohibited by U.S. law (Marine Mammal Protection Act).
