False killer whale at surface. Contrary to what its name implies, the false killer whale is not directly related to the killer whale. However, as with the killer whale, it is also not a whale but a large member of the dolphin family. It is often referred to as 'blackfish' with similar species such as the pygmy killer whale, melon-headed whale, and pilot whale.
False killer whales investigated a tour boat in Hawaii recently and the crew captured mesmerizing underwater footage of the mysterious mammals, including one that seemed to be smiling for the camera. The pod of false killer whales, which like orcas are members of the dolphin family, was encountered during a Wild Side Specialty Tours expedition off West Oahu. The mammals became curious about the submerged camera used to document their behavior.
