Field Notes
It is a very windy, wet day at Kettle Cove. The waves were coming in fast. We are making our way over the field of seaweed and rocks. It smells like seaweed and was cloudy. I hear the waves crashing. The seaweed is wet and slippery. I find it difficult that I keep slipping on the seaweed. I am surprised that the Sea Potato looks like thin paper or a dried out hollow grape. The Sea Potato is very hard to find and it is buried up at the top of the hill in the back of the seaweed pile. It is windy and looks like it is going to rain soon, but doesn’t end up raining too much.

This is the Sea Potato. It is commonly known to be 1cm to 7cm long. The Sea Potato can also collapse on itself if it gets too big. It does not have any stems or anything inside to hold up the outside skin. You can see the size by the ruler, and the wrinkles in the picture.
