Plural of ganoid; multiple primitive fish with shiny, enamel-coated scales.
From ganoid (Greek ganos + oid) plus -s (English plural marker). Standard pluralization of the ganoid noun form.
Modern ganoids like gar fish and bowfins are basically living time capsules—they've kept the same scale design for so long that studying them is like looking at a 200-million-year-old instruction manual for how to build perfect fish armor.
