With the exception of insects, a majority of invertebrates live in the ocean. An  Invertebrate is an animal that does not possess a backbone.  In class, we examined Phylum Porifera (sponges) Experiment 4.1 and Phylum Cnidaria (jellyfish, corals and sea anemones).  Experiment 4.A.

On our field trip we found comb jellyfish and a moon jellyfish.

Box jellyfish are the most toxic.


Wasn’t that cool!  I wanted to add these videos from all of our discussion in class.  I also want to encourage students to become our future scientists!  The early Wednesday morning clouds proved disappointing for my viewing of the lunar eclipse.  It did happen, but I just could not see it.  Did anyone else get a good view/photo?
