Galeocerdo cuvier (Péron & Lesueur)

( Fig. 4C )

A tissue sample was taken from each of two frozen immature specimens of Galeocerdo cuvier (SL-113 and SL- 118) collected in 2017 from the Valaichchenai fisheries harbor in the Eastern Province. These specimens have now been deposited in the BRT Ichthyology Collection (SL-113, BRT-I 0004; SL-118, BRT-I 0005). These specimens were identical in NADH2 sequence and grouped most closely with our reference specimen of this species (BJ-382; JQ519164 ) from the Gulf of California in the tree resulting from the Neighbor-Joining analysis; they differed from the latter specimen by 2 bp.

This is the name currently applied to this species in Sri Lanka (e.g., De Silva 1984 –1985, 2006, 2015; De Bruin et al. 1995; Morón et al. 1998; Joseph 1999).

Taxon names are followed by country, host specimen number (in parentheses), and GenBank number. Outgroup taxa used in each analysis were omitted from the individual trees. Scale bar values indicate substitutions per site. Specimens deposited in the Blue Resources Trust Ichthyology Collection are indicted by stars (see text for details). A.
