Coastal Kelp Forest

Did you know?

Girl or boy? For a California sheephead fish, it depends when you ask. They start out female, then turn male around age 10. Come to the Kelp Forest and meet our sheephead, Buddy!

Explore the Kelp

An underwater forest
right here in the Zoo.
Tall strands of kelp wave gently in the current. Vermillion, pink and gold fish dart between the “leaves”, a leopard shark moseys along and a moray eel peers out. A replica of the enormous giant kelp forests of the Pacific coast, this habitat highlights a delicate ecosystem.
Waving strands
give food, shelter, life.
Kelp (Macrocystis pyrifera) is a plant, not an animal, but it’s crucial to the ecosystem of a kelp forest. A towering seaweed, it provides food and shelter for otters, invertebrates and over 100 fish species. It can live for many years, growing up to 18 inches in a day and forming forests over 150 feet tall.

Not just an underbite
Sheephead like to crunch
California sheephead have strong teeth to crunch the lobster, crab, sea urchin and mussels they love to eat, and special bones in their throats to finish the job.
To avoid predators, they wrap themselves in a mucus cocoon to rest at night. Predators can’t smell them through the mucus.
Fade to black (and white)
Rockfish go deep
Flag rockfish hide while young under protective kelp leaves. As they grow, they move to deeper water – often 200-700 feet, and sometimes over 1,300 feet deep.
Down this far, red colors fade and darken, and this red striped fish turns almost to black and white, like a zebra.
Hot lips
for flagfish
Treefish are also known as “lipstick fish” because of the bright red coloring that warns other fish out of their territory.
They also raise their dorsal fins, facing off with open mouths and sometimes locking jaws with intruders to scare them off.

Help the kelp

by helping otters.

THE THREAT: Kelp forests such as those in California and southern Australia have in the past been decimated by sea urchins, who eat through the kelp without enough sea otters to keep them in check.

TAKE ACTION: For 15 years our Zoo has taken part in the Washington Sea Otter Survey. Help protect otters – and other marine mammals – by reducing your plastic use and keeping trash out of the ocean.

Behind the Shimmer

It’s more than just a play of light. Wander down the ramps of the new Pacific Seas Aquarium, and you’ll pass through shimmers of colored light. You’re immersed in their play and flicker, as if swimming through a sunlit lagoon. It’s art – the light installation “Shimmer,” by California artist Gordon Huether – but the … Continued

Lunchtime in the aquarium

Animal care aide Jordan Jirik lies flat on her stomach, her head hanging over the top of Baja Bay’s 280,000-gallon habitat. Below her, five hungry spotted eagle rays swim eagerly up to a large black sign with a big white X emblazoned on it. It’s their feeding-station target. And when it appears in the water, … Continued

We opened the Pacific Seas Aquarium!

Two dozen necks crane up, up, up, eyes riveted on the scene above, as four hammerhead sharks cruise overhead. Sunny the sea turtle joins the scene, swimming unhurriedly by and then diving deeper into his home. Suddenly, two eagle rays “fly” overhead, their pectoral fins gently flapping up and down to propel them through the … Continued
