They are believed to prefer off shore waters. description = The Pygmy Sperm Whale is one of three species of whale in the sperm whale family.

The tusk can be up to 3 m (nearly 10 ft) long (compared with a body length of 4–5 m [13–16 ft]) and weigh up to 10 kg (22 lb).About one in 500 males has two tusks which occurs when the right tooth normally small also grows out. Although rare a female narwhal may also produce a tusk. Species ...
