Optic Lobe Metamorphosis in the Stomatopod Crustacean Alima pacifica
Meeting Abstract 82-6 Saturday, Jan. 7 09:15 – 09:30 Optic Lobe Metamorphosis in the Stomatopod Crustacean Alima pacifica LIN, C*; CRONIN, TW; University of Maryland Baltimore County linc@umbc.edu The compound eyes of stomatopod crustaceans have unusual ommatidial rows at the equator called the midband that are typically specialized for color and polarization vision. Beneath the retina, this […]
