Deep-water observation of scalloped hammerhead Sphyrna lewini in the western Indian Ocean off Tanzania
Get PDFA scalloped hammerhead Sphyrna lewini was observed opportunistically from a remotely operated vehicle 1 m off the seabed at 1042 m depth, during hydrocarbon exploration activities in the Ruvuma Basin off Tanzania. The observation, which occurred during night hours, is the deepest accurately recorded for this species and the first deep-water record for the Indian Ocean. The record adds support for the occurrence in deep water during night hours being a widespread and possibly common behaviour in this species, and further expands a small but growing literature that meso- and bathypelagic environments may be of greater importance to elasmobranchs previously considered to be primarily epipelagic

Triakidae Houndsharks
No full textTriakidae (Houndsharks) <p> A record of the blacktip tope <i>Hypogaleus hyugaensis</i> (Miyosi, 1939) in the Gulf was first reported in Compagno (1984), apparently inserted without this author’s knowledge and on an uncertain basis (LJV Compagno, pers. comm.). Randall (1986, Fig. 39) presented a photograph of the then undescribed <i>Paragaleus randalli</i> from Bahrain as <i>H. hyugaensis</i>. Currently <i>H. hyugaensis</i> is known from southern and eastern Africa, Australia, Taiwan and Japan, and seems to be a deeper-water species than <i>P. randalli</i> (LJV Compagno, pers. comm.). As yet there is no evidence for this species in the Gulf.</p>Published as part of <i>Moore, Alec B.

Sphyrnidae
No full textSphyrnidae (Hammerhead sharks) The winghead shark Eusphyra blochii (Cuvier, 1816) has been reported from the Gulf but without evidence (Randall 1986; Carpenter et al. 1997 a), although its occurrence in the Gulf of Oman near Jask is proven (Blegvad 1944, as Zygaena blochii). Reports of the smooth hammerhead shark Sphyrna zygaena (Linnaeus, 1758) in the Gulf were doubted by Randall (1996), and our data support this, although a number of specimens of this species have recently been confirmed from Oman (Henderson & Reeve 2011).Published as part of Moore, Alec B. M., Ward, Robert D. & Peirce, Richard, 2012, Sharks of the Persian (Arabian) Gulf: a first annotated checklist (Chondrichthyes: Elasmobranchii), pp. 1-16 in Zootaxa 3167 on page 13, DOI: 10.5281/zenodo.27977
Alopiidae
No full textAlopiidae (Thresher sharks) No confirmed Gulf records. Goubanov & Shleib (1980) reported thresher shark Alopias vulpinus (Bonnaterre, 1788) as “very seldom seen in the Gulf, only in its southern areas”, although Randall (1996) regarded this as doubtful. Bigeye thresher A. superciliosus (Lowe, 1841) was regarded by Compagno et al. (2005) as possibly occurring in the Gulf, and both this species and the pelagic thresher A. pelagicus Nakamura, 1935 are known from Oman (Henderson et al. 2007).Published as part of Moore, Alec B. M., Ward, Robert D. & Peirce, Richard, 2012, Sharks of the Persian (Arabian) Gulf: a first annotated checklist (Chondrichthyes: Elasmobranchii), pp. 1-16 in Zootaxa 3167 on page 12, DOI: 10.5281/zenodo.27977
