It is possible to mistake the pantropical spotted dolphin with the coastal spotted dolphin and Atlantic spotted dolphin. However, the coastal dolphin is a subspecies of the pantropical spotted dolphin while the Atlantic dolphin is a different species in the Stenella genus. It is often hard to differentiate between the varieties as their coloration is very similar, but the pantropical spotted dolphin is often slightly smaller at full maturity and is found in a wider stretch of ocean.
The pantropical spotted dolphin is unique for its unexplained association with yellow fin tuna. In fact, the species gained international notoriety in the late 1970s and 1980s as the species was pushed to the brink of annihilation due to their association with the yellow fin tuna. As fishermen around the globe used purse-seine nets to trap the tuna, they would trap the dolphins in their nets as well, leading to suffocation of the dolphins. An intense focus on dolphin-safe tuna fishing standards in the United States has helped bring the pantropical spotted dolphins' numbers back up, but its association with the yellow fin tuna and questionable fishing habits by mankind remain the biggest threats to the pantropical spotted dolphin.
The Bridled dolphin, narrow-snouted dolphin, pantropical spotted dolphin is listed as Conservation Dependent (LR/cd), the focus of a continuing taxon-specific or habitat-specific conservation programme targeted towards the taxon in question, the cessation of which would result in the taxon qualifying for one of the threatened categories below within a period of five years, on the IUCN Red List of Threatened Species
