Etymology: Galeus: galeos, a small shark or dogfish according to Aristotle and others (See ETYFish); mincaronei: In honor of ichthyologist Michael Maia Mincarone (b. 1971), for his “extensive work and tireless dedication” as collections manager of the Museu Oceanográfico do Vale do Itajaí (Brazil) (See ETYFish).
Eponymy: Dr Michael Maia Mincarone (d: 1971) is a Brazilian ichthyologist who is a Professor at Universidade Federal do Rio de Janeiro. [...] (Ref. 128868), visit book page.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
Diagnosis: Distinguished by the following characters (vs. Galeus antillensis): shorter prepectoral length 16.1%-18.6% (vs. 19.4-21.8%); smaller pectoral anterior margin (8.9-10.1% (vs. 10.2-12.7%); smaller pectoral posterior margin 7.4-8.5% (vs. 8.8-11.6%); and fewer number of diplospondylous vertebrae 35-36, n=3 (vs. 39-78, n=4) (Ref. 56495).
The species inhabits deep-reefs in the shelf break and on the continental slope, and is often found in depths greater than 400 meters, with gorgonians, hard corals, tube sponges, crinoids, ophiuroids, and a great number of the sympatric scyliorhinid shark Scyliorhinus haeckelii (Ref. 56495). Minimum depth from Ref. 58018.
此魚種深地居住於-礁在大陸棚休息中與在大陸斜坡上, 而且時常發現於深度大於 400 公尺, 藉由柳珊瑚，堅硬的珊瑚，管海綿，海百合類動物，陽燧足 , 與很多的分佈區重疊的 scyliorhinid 鯊魚 Scyliorhinus haeckelii.(參考文獻 56495)
