Tides are of course a big part of your day at the beach. When the tide goes out at some beaches, pools of still ocean water are left behind. Teeming with life, tidepools are treasure troves for exploration.
Here, you’ll find some of the toughest critters on the beach. They have to be able to withstand increased salinity as water is evaporated from the pool between tides.
Some, like the snail, have adapted to keep from drying out until the tide comes back in. They have adapted a very strong clamping process when they attach to rock using their foot organ.
When they clamp onto rocks, they have a bubble of water trapped under their shell. This bubble keeps the snail hydrated and prevents it from drying out during low tide.
In addition to snails, you can find seaweed, crabs, clams and urchins in our tidepools.
Dr. Ramsay notes it is great to explore the wonders of the tidepools but it is just as important to put them back where you found them. After all, these specialized creatures are built for their specific ecosystem.
