They are a small (up to 0.5 meters; 1.64 feet) deepwater shark, and are often confused with E. robinsi. Little is known of its biology, except that they are ovoviviparous, have a small litter size (4 to 5 pups) and are taken as bycatch in some deepwater fisheries. They are listed as Least Concern (LC) by the IUCN, as they seem to not have any significant threats. However, like many deepwater chondrichthyans, there is more information needed in order to properly assess them. Until then…
- Continental slope: The steep slope from a continental shelf to the ocean floor; usually around 20 km (12.4 miles) wide and made up of mud and silt substrate. It is an ideal area for deepsea fishing.
- Chondrichtyans: the class containing cartilaginous fishes.
- Insular slope: The shelf around an island.
- Ovoviviparous: Also known as aplacental viviparous; bearing live young which eat any unfertilized eggs and each other while in the womb.
- IUCN: International Union for Conservation of Nature.
- Trawl fisheries: Fisheries that pull a fishing net through the water behind one or more boats.
- Commercial fishery: The activity of catching fish and other seafood for profit.
