This is a sea urchin, one of the animals we learned about when we went to the aquarium. The aquarium was filled with valuable learning experiences, anything from anemones being homes to fish, but poisoned to humans, right to penguins and anything in between. I chose the sea urchin because they are very interesting. They are in the phylum echinoderm. They are very interesting because the mouth is at the bottom and they can be eaten when the hard and spiny shell is cracked open. Very interesting animals, and that is why I chose the sea urchins.
The sea urchin was fun to see the reactions from students when they held it.
