Range of the blacktailed spurdog (in blue) |
The blacktailed spurdog (Squalus melanurus) is a dogfish, a member of the family Squalidae, found around New Caledonia in the central Pacific Ocean, at depths from 320 to 320 m. Its length is up to 75 cm.
Its reproduction is ovoviviparous.
The blacktailed spurdog has been seldom studied for
parasites. The 1 mm-long
monogenean Triloculotrema chisholmae has been described in 2009 from three specimens found in the nasal tissue of a single shark caught off
New Caledonia.
[2]
T. chisholmae was the second species described in the
genus Triloculotrema Kearn, 1993 (family
Monocotylidae).
[3]
Species of Triloculotrema appear to be limited to deep-sea sharks, either triakids or squalids (possibly etmopterids).
[2]
The blacktailed spurdog is also the host of external parasites such as the aegid
isopod Aega angustata on the skin.
[4] Internal parasites include several
trypanorhynch
cestodes in the
spiral intestine, such as Vittirhynchus squali and Gilquinia sp.
