Are sperm whales endangered?

1
VIEWS

The IUCN considers sperm whales to be vulnerable to extinction, but after a 2008 assessment, experts are unsure if the sperm whale population is increasing, decreasing or stable. Scientists roughly estimate that there were about 1.1 million individuals in 1700 and the population dropped by about 67% to 360,000 individuals by the 1990s, due to whaling. Large-scale, commercial whaling ceased in about 1980 but it’s not clear whether sperm whale populations have since increased, or are still decreasing. Japan is currently the only country still hunting sperm whales, according to ZSL.
