 Systematics

Phylum: Vertebates (Chordata)

Class: Carlilagenous Fishes (Chondrichthyes)
  Order: Dogfish sharks (Squaliformes)
    Family: Dogfish sharks (Squalidae)

 Name

Scientific: Euprotomicroides zantedeschia
German: Schwanzlichthai
English: Taillight shark
French: Squale à queue claire
Spanish: Tollo rabo claro


 Appearance

Very small, with a conical, blunt and long snout. Gill openings increase from front to back, and the fifth one has twice the length of the first one. Dorsal fins without spines. Origin of the first dorsal fin is behind the free rear ends of the pectorals. Uniquely shaped pectoral fins. Small keel on peduncle. No anal fin.

 Coloration

Blackish brown, with conspicuous white margins on fins.

 Distribution

Wide distribution possible but not proven yet since only 2 specimens have been found. Western Atlantic: Uruguay. Eastern Atlantic: South Africa.

 Biology

Little-known dwarf shark. Based on the shape and size of the pectoral fins it is suggested they show pectoral propulsion or at least pectoral hovering.

 Feeding

Unknown. Based on their sharp lower teeth and strong jaw structure one can assume that they can feed on relatively large prey.

 Size

About 40 cm, possibly larger.

 Reproduction

Unknown. Probably aplacental viviparous (ovoviviparous).

 Similar Species

Similar to LK++ Pymgy shark Eupromicrus bispinatus but the first dorsal fin of the pgymy shark is more posteriorly positioned.

 Endangerment
