3 Pictures

I took these pictures when we took our trip to Minnesota this summer, when we went to the aquarium in the Mall of America. I didn't have my ring with me, but I can guarantee I took these myself.

This fish is an ecotherm, because it is a cold blooded animal.

This picture is an example of a population. A population is many of the same species living together in the same place at the same time.

This jellyfish has radial symmetry, because it's body is symmetrical from the central point.
