How to go tidepooling on California’s rocky shores

What is tidepooling?

Twice a day, rising tides submerge the rocky formations along the ocean’s edge. Urchins, mussels, fish, and other animals must hold on tightly to avoid being swept away by crashing waves.

Some animals, like snails and chitons, use a strong muscular foot to cling to rocks. California mussels attach themselves with tough fibers called byssal threads. Others, like anemones and seaweeds, survive by bending with the waves instead of resisting them.

When the tide recedes, these animals face a different challenge. Exposed to sun and air, they must stay hydrated until the water returns. Tide pools can warm up and become saltier as water evaporates.

Many animals have special adaptations to survive these conditions. Mussels clamp their shells closed to keep moisture inside. Soft-bodied anemones often huddle together to reduce exposure. Fish like sculpins move to deeper pools while the tide is out, returning to their home pools when the tide comes back in.

Common tide pool animals you might see  

California’s rocky tide pools are home to a fascinating community of marine life. As you explore, you might spot animals such as:

• California mussels
• Sea anemones
• Sculpins
• Chitons
• Marine snails

Each of these animals is specially adapted to survive the challenging conditions of the intertidal zone.

Intertidal zones explained

As you explore the rocky shore, you may notice different bands of life along the rocks. These areas are called intertidal zones, and each supports its own community of plants and animals.

The high intertidal zone is closest to land. Animals like periwinkles and barnacles spend most of their time out of the water.

Below that is the mid intertidal zone, which is covered and uncovered twice a day by the rising and falling tide.

The low intertidal zone is only visible during the lowest tides. Most of the time, this area remains underwater and supports a rich diversity of marine life.

Best time to go tidepooling

The best time to explore tide pools is during low tide, when the ocean recedes and reveals the rocky shore.

Check a local tide chart before your visit and plan to arrive about one hour before the lowest tide. This gives you plenty of time to explore as more tide pools become visible.

Winter and spring often bring the lowest daytime tides, making them some of the best seasons for tidepooling along the California coast

Tidepooling tips for visitors

Exploring tide pools can be exciting and rewarding. Keep these tips in mind while visiting the rocky shore:

• Go tidepooling with a buddy.
• Always keep an eye on the ocean and watch for incoming waves.
• Watch where you step to avoid damaging fragile habitats.
• Stay low to the ground—you’ll see more animals and reduce your chance of slipping.

How to protect tide pool animals

You will undoubtedly encounter many amazing animals in Monterey's tide pools. Have a conversation with your children about how to care for these critters before heading off to explore.

• Look closely. Instead of picking them up, quietly stop and watch the rocky shore animals for a few minutes. You will see and learn much more this way. Touching with dry fingers can damage delicate surfaces. If you do touch an animal, wet your hands first.
• Touch gently. If the animal tries to escape, let it go.
• Leave ocean animals in their homes. Most will die if pried from the rocks, and all of them need the oxygen from seawater to breathe.
• Always return animals exactly as you found them. Replace any rocks or shells that you turn over — they are homes for many animals. In the Monterey Bay Nationl Marine Sanctuary, plants, animals, rocks and shells are protected. Collecting them is not allowed, even those found high on the beach. Collection will result in fines.
• Remember to use all your senses. Close your eyes and listen to the sounds of the waves and birds; feel the cool ocean breeze; smell the salty air.

Tidepool safety tips

Rocky shores can be slippery and unpredictable. Take a few precautions to stay safe:

• Watch where you step—rocks can be sharp, and seaweed can be slippery.
• Never turn your back on the ocean. Large waves can be dangerous, even deadly.
• Wear sturdy shoes with good traction.
• Check the tide schedule before visiting to plan your trip during low tide.

Preserve our sanctuary

The Monterey Bay coastline, including its tide pools, is part of Monterey Bay National Marine Sanctuary. The sanctuary protects the many marine habitats and plants and animals living along our coast.

Some activities that could harm the ocean's health, such as oil drilling, are prohibited. But many others, such as fishing, boating and exploring the coastline are allowed. Visiting the rocky shore can provide you and your children with an exciting look at ocean plants and animals in their native habitat.

Most importantly, tell others what you've learned and what you're doing to help the oceans. Conservation of the ocean starts with you.
