The beauty in Anatomy & Histopathology of Mollusks

Today was full of beautiful marine inverts and microscopy! Morgan and I examined the California mussel, Mytilus californianus, and the Pacific oyster, Crassostrea gigas (below).

Later we also examined prepped slides of abalone and observed this sweet design of nature (the radula epithelial tissue), which constantly deposits new layers to the radula, the molluscan feeding structure.

I leave you with one last beautiful specimen we examined today, from another Phylum, the Pacific blood star, Henricia leviuscula. Stunning!
