Coastal Marine Biology: Family Style at the Tidepools


We were able to fit in some time at the tide pools along the Oregon Coast. We have started a study of marine biology this year and it was a perfect time to investigate up close the life in these pockets of water and at the rocky shore line.

The first thing we learned was that we needed to know the high and low tides for each day. It made a big difference in what we would see. One day we timed it just right and we found ourselves all alone at a great area of tide pools.

There had been a storm during the night before and the area was covered in seaweed. The whole beach area was filled in with piles of kelp….mostly bullwhip kelp.

The boys quickly learned how to look carefully in and around the crevices of the rocks for interesting things to view.

We saw anemones.

Hermit Crabs

Snails.

Sea Stars

Periwinkles

Someone in our family got wet because he was not paying attention to the waves coming in. I thought he was going to be stranded out on the rocks but he made it in safely……a little wet though. If you look closely in the photo above, you can see him way out on the rocks.

We all learned so much from this experience and now when we read in our textbook about marine life, we have a better understanding of just what they are talking about.

The Handbook of Nature Study has a few pages of information about marine invertebrates. Page 418 talks about shells of Florida and the East Coast and page 430 has a little information on seashore creatures.

After our tidepool adventure, the boys decided to build a structure with driftwood, rocks, and seaweed. This became a tradition on this trip and they came up with very elaborate ways to build on the beach.

Great memories and a lot of learning.
