The striped lantern shark ( Etmopterus bullisi ) is a species of the genus Etmopterus within the lantern sharks (Etmopterinae; also classified as the family Etmopteridae). Etmopterus bullisi reaches an average body length of about 26 centimeters. The range of this species includes parts of the Caribbean , the coastal areas of Florida and South America.
Appearance and characteristics
Etmopterus bullisi is a small shark with a known body length of about 26 centimeters. It has an elongated body typical of the lantern sharks with a long and at the same time wide and flattened head. The body color is dark soot gray with a black underside. It has a drawing of light stripes that extends from the eyes to the first dorsal fin (which is why it was given the common name "Lined Lanternshark"). There are also black drawings in the area of the fins. On the head, back and sides of the body there are conspicuous rows of tooth scales that extend to the base of the caudal fin. It also has the light organs typical of the lantern sharks on the belly side.
It has no anal fin and two dorsal fins with the order-typical spines in front of the dorsal fins. The first dorsal fin begins behind the pectoral fins over their rear edge and is smaller than the second. The distance between the dorsal fins is comparatively short. The tail is long. Like all species in the family, the animals have five gill slits , which are very short in this species, and have an injection hole behind the eye.
distribution
The range of this species includes parts of the Caribbean , the coastal areas of Florida and South America. Here he is known from depths of 275 to 824 meters, where he lives mostly below 350 meters.
Way of life
Etmopterus bullisi lives in the area of the continental shelf on or near the sea floor. Like other sharks, it feeds in a predatory manner, likely on smaller fish and invertebrates. Little data is available about his way of life.
Like other species of order, it is viviparous ( ovoviviparous ).
Danger
Etmopterus bullisi is not listed in a hazard category in the IUCN Red List due to the lack of data on its way of life and its populations. However, it is of no importance as a food fish and is therefore not fished specifically.
