In the late part of 1993 off Baltimore Southern Ireland a much larger specimen was hooked by Stefano and handed after 45 minutes to Keith Walker who brought it to the surface.
Colours range from dark brown to dark silvery grey with large, opalescent eyes.
They are ovoviviparous, which means that the eggs hatch inside the mother body, so the young are born alive and fully formed. A captured female of 4.21 m TL from off Church Rock, California, contained 51 near term embryos. This very large but little known shark is a rare visitor to our coastal waters. A few specimens of up to 54.3 kg, have been caught recently by boat anglers around Dingle Bay and Kinsale Bay, County Kerry off South West Ireland. Marine Biologists survey the deep waters for fish and sharks, along the edge of the continental shelf.
