Definition

A shallow pool of seawater trapped among rocks on a shoreline after the tide recedes, creating a temporary marine habitat teeming with algae, anemones, starfish, crabs, and other coastal organisms. These miniature ecosystems experience extreme environmental fluctuations in temperature, salinity, and oxygen levels.

Example Usage

The children spent hours exploring the tide pools, discovering colorful sea stars and hermit crabs hiding beneath the seaweed.

Origin

Compound of 'tide' (the regular rising and falling of sea level) and 'pool' (a small body of water), a descriptive term for these natural formations.

Fun Fact

Tide pool organisms have evolved remarkable adaptations to survive extreme conditions—some sea stars can tolerate dramatic temperature swings, and certain fish can breathe air when pools become oxygen-depleted.
