Sand dollars are of the phylum Echinodermata, class Echinoidea. Xy found this one on the beach in South Carolina.
Back when I was working on Interactive Taxonomic Zoology, I knew the phylum and class for lots of creatures. But while walking on the beach, I found I’d forgotten. I couldn’t even remember the three classes of sponges.
Just cruisin’ around, found your blog, couldn’t resist saying “hello”.
I know and love the South Carolina coast – lived and worked directly on the shore for about 15 years. Now back in Augusta, GA my family’s home for about 4 generations.
Happy New Year!
