Narwhals have a life span of around 30 to 40 years, with females reaching reproductive maturity at around age 5 and males a few years later at the age of 8.
Currently, the population of narwhal whales around the world is estimated to be somewhere around 50,000; however, as fishermen continue to deplete the world of fish and other marine life, hunters go unchecked, and their habitat dwindles these numbers are declining. Some nations, such as Greenland, have attempted to put quotas or limits on the hunting of the sea unicorn to no avail. Being sought after for their tusks as well as the meat, narwhals are often targeted by whalers and hunters and mercylessly slaughtered in spite of the fact that these intelligent and social animals are currently on the IUCN's Red List. Pollution and climate change are also threatening the survival of the narwhal whale.
Many conservation and animal right's groups around the globe are fighting to try to raise awareness to save the unicorn of the sea, whose fate is yet to be determined.
