Phylum Sorting

Today I learned about:
-Over the past few days I thought "Anthopoda" was and Invertebrate Phylum. But Anthropoda actually refers to humans, what I was meant to be calling it was "Arthopoda" which refers to invertebrates like spiders, hermit crabs etc.
-I learned that sea horses and sting rays (just to name a few) are Chordates, which is the same as humans. Although humans are vertebrates, whereas sting rays and sea horses are invertebrates.
-One more thing I found interesting in today's lesson was that Octopi and Bivalves are in the same Phylum; *Mollusca. A bivalve looks like one of those regular shells you might find on the beach.
