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).

Kurzbeschreibung
Morphologie | Morphometrie
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.
