Etymology: Galeus: galeos, a small shark or dogfish according to Aristotle and others. (See ETYFish); corriganae: In honor of Australian molecular geneticist Shannon Corrigan (b. 1982), “whose extensive molecular population and phylogenetic work on sharks has contributed toward an improved understanding of their alpha taxonomy and phylogenetic relationships” (she also captured some of the molecular data used in this description). (See ETYFish).

Short description
Identification keys | Morphology | Morphometrics
This small and slender species is distinguished by the following characters: head relatively broad; interorbital space 7.2-7.8% TL; pelvic-anal space 12.2-13.0% TL; relatively small anal fin with base length 7.8-8.6% TL; anal-fin posterior margin 5.2-6.3% TL; relatively short prepectoral length, about 18.4-21.5% TL; labial furrows are moderately long, not confined to mouth corners, uppers 2.2-2.9% TL; enlarged denticle crest of upper caudal fin originating anterior to origin of ventral caudal lobe; with denticles on elevated portion of supracaudal crest forming 2-4 central rows of denticles between much larger obliquely positioned lateral rows; subcaudal crest absent; colour of anterior margin of pectoral fins black; anterior half of dorsal fins almost entirely dark or dusky; precaudal centra 83-86 (Ref. 116735).
Size vary with 3 juveniles at 20.3-27.1 cm TL, 4 adolescent males at 28.2-37.2 cm TL and a single female 27.8 cm TL (Ref. 116735).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (27 of 100).
