In recent years Azorean fishermen reported the presence of the smalltooth sand tiger shark, Odontaspis ferox (Risso, 1810), a very rare demersal shark species, associated with insular shelves and slopes, with occasional incursions into shallow waters and of poorly known biology and ecology. There are fourteen new records of this species, between 1996 and 2014, captured by spearfishing, harpoons, hand lines, or entangled in fishing gear in the Azores. These records were analysed and complemented with fishermen interviews, providing new locations and new biological data for this species. Also, specimens photographs were studied and post-mortem analysis were carefully carried out in one individual. This species is rare and captured only as bycatch in shallow waters. More detailed information on this species is critically needed in order to assess its conservation status and implement management guidelines. Bycatch statistics are crucial in this respect.

The smalltooth sand tiger shark Odontaspis ferox (Risso, 1810 ) appears to have an extensive and fragmented distribution in tropical and warm-temperate worldwide oceans. One female of O. ferox was caught and released by a small-scale fishery vessel in Ría de Arousa (Northwest of Spain), subsequently stranded still alive on the coast (42°33’18.4\"N 8°49’18.3\"O) after a few hours. The individual (336 cm total length, weight ~ 300 kg) was identified based on a collection of features including the characteristic dentition, body morphology and by molecular assignment. This is the first confirmed record of O. ferox in Galician waters. This finding complements the knowledge of the geographic distribution and occurrence of this rare and sparse species in the Northeastern Atlantic.

Catching of extremely large (520 cm) specimens of smalltooth sand tiger Odontaspis cf. ferox (Odontaspididae) near the southern part of Walvis Ridge (Southeastern Atlantic open waters) is documented for the first time. This species was found earlier in the Atlantic Ocean in the near-continental waters and island regions of the northeastern Atlantic from the Bay of Biscay to Morocco, including the Mediterranean Sea. In the open waters of the southeastern Atlantic, the species was not recorded previously.
