Examples

    Think Progress » “When I caught a 7.5 pound perch in my lake”

  • “I tried to follow Agassiz's scheme of division into the order of ctenoids and ganoids, with the result that I found one of my species of side-swimmers had cycloid scales on one side and ctenoid on the other.”

    Louis Agassiz as a Teacher

  • “So long as the strongly-armed ganoidal order prevailed in nature, the sharks were furnished with massive crushing teeth; but when the ganoids waned in creation, and the soft-scaled cycloid and ctenoid orders took and amply filled the place which they had left vacant, the well known modern form of sharks 'teeth was introduced, -- a form much rather suited for cutting soft bodies than for crushing hard ones.”

    The Testimony of the Rocks or, Geology in Its Bearings on the Two Theologies, Natural and Revealed

  • “Another kind of scale is the ctenoid which are thin flexible scales where the posterior end has comb-like teeth, and are believed to reduce drag on the fish when swimming in the water.”
