Etymology: Ichthyomyzon: ichthys, fish; myzon (Gr.), to suck (borrowed from Petromyzon), i.e., a sucking fish, referring to their suctorial behavior (See ETYFish); gagei: In honor of American histologist and embryologist Simon Henry Gage (1851-1944), Cornell University (Ithaca, New York, USA), “one of the foremost students of the lampreys,” who brought this “interesting and distinct species” to the authors’ attention (See ETYFish).
Eponymy: Simon Henry Gage (1851–1944) was a histologist and embryologist at Cornell University, which awarded his first degree (1877). [...] (Ref. 128868), visit book page.

Biologi     Daftar kata (contoh epibenthic)

Freshwater (Ref. 89241). Adults inhabit gravel and sand riffles, and runs of creeks and small rivers. Ammocoete larvae occur in flowing water near sand bars and debris. Non-parasitic (Ref. 5723). Average fecundities varied from 713-2,448 eggs/female among 19 localities across the distributional range (Ref. 89241).
