Angular roughshark
species of shark

The angular roughshark (Oxynotus centrina) is a rough shark of the family Oxynotidae.
Taxonomy
Biologist Carl Linnaeus described the angular roughshark, O. centrina, in 1758. This name was finalized and accepted by the scientific community as the official name for the species in 1976.
Description
At birth, they are less than 25 cm (9.8 in) and they mature at about 50 cm (20 in). Most records are of individuals less than 1 m (3.3 ft), but they can reach about 1.5 m (4.9 ft). Individuals from the Mediterranean Sea usually measure less than 80 cm (2.6 ft). Their litter size is seven or eight pups off Angola to 23 in the Mediterranean. They have ridges over their eyes that expand into large, rounded knobs, which are covered with enlarged denticles – these are absent in other species of rough sharks. They possess very large spiracles that are vertically elongated, being almost as high as the length of their eyes. Their first dorsal spine is oriented slightly forward.

Why this record matters
“Angular roughshark” is worth following because a concise public description often conceals a longer documentary argument. Here, Angular, roughshark and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 21, 2026. The linked authority identifier is Q1089264. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1758 and 1976.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
