5/26/2023 0 Comments Rocky shores and tidal poolsConditions are almost constantly changing, so organisms that reside here need to be flexible in their requirements and hardy in their responses. Life in the intertidal zone is a bit more difficult than one might imagine. This area is always covered in water and is where more invertebrates and even fish are found. Subtidal zone: The deepest point of a rock pool is the subtidal zone. It’s more likely to see snails, crabs, sea stars, and more anemones here. Next is the mid-zone and low-zone, which host more life as deepness, water, food, and shelter increase. The high-zone is closest to the splash zone, this is where barnacles, snails, crabs, and the periodic anemone are found. Consisting of three regions, this zone has a lot to offer. It’s sort of like the goldilocks zone of rockpools spending part of the day underwater, and part exposed. Intertidal zone: The intertidal zone lies between the splash zone & the subtidal zone. Unsurprisingly, the only life found here is the occasional barnacle and some algae. The only water that is present here is the occasional splash or mist from the sea, resulting in extremely harsh conditions like constant sun exposure, high temperatures, increased salinity levels and constant moisture loss. Splash zone: This zone is the furthest from the ocean, making it the hardest zone to live in. While species might be commonly found throughout nearby pools, each pool has its own unique ecology with varying dominant species and available resources.Īll tide pools consist of three zones: splash zone, intertidal zone, and subtidal zone. Each pool is its own microcosm, a mini world filled with incredible life, some of which are permanent residents and others come and go with the tides.
