such as Daley's use of 16s mitochondrial DNA listed above, older data listed for gulper sharks could be for ones other than the granulosus, such as the dumb gulper shark. This also means that current populations numbers could account for other dogfish than just the gulper sharks. Lastly, due to the frequency and patterns of migration, the recorded gulper shark populations may be inaccurate. References Centrophorus Fish described in 1801
