Many shark species are victims of increasing fishing pressure, even if they are not targeted themselves: as bycatch. That is a big problem if they are endemic to only a small range or show only a low fecundity – the African ribbontail catshark (Eridacnis sinuans) is both.

Living solely in deep waters off Mozambique (and between this island and the coasts of South Africa and Tanzania), fortunately only part of its range is subject to intensive bottom trawl fisheries. At least for now.

Sharks of the family Proscylliidae, also called false catsharks, look a lot like catsharks, but their first dorsal fin starts as soon as their pectoral fins end.

Being not quite as small as its sister species, the pygmy ribbontail catshark,  female African ribbontail catsharks of about 14 in – 35 cm – length give birth to 2 (one from each uterus), between 6 and 6.7 in – 15 and 17 cm – long living pups (ovoviviparous).
