Balaenoptera acutorostrata is a species of baleen whale commonly known as the minke whale. It belongs to the family Balaenopteridae, which includes the largest animals on Earth.
The minke whale is characterized by its relatively small size compared to other baleen whales, with adults reaching lengths between 7 to 10 meters (23 to 33 feet) and weighing around 5 to 10 tons. It has a streamlined body shape, a pointed snout, and a dorsal fin located two-thirds down its back. Its skin is usually dark grey or black on top, with a lighter coloration on the underside.
Feeding primarily on small schooling fish, krill, and other small marine organisms, the minke whale is known for its feeding techniques, including surface lunging and 'bubble-net' feeding. It has baleen plates within its upper jaw that enable it to filter feed by engulfing large volumes of water and then expelling it through the baleen, trapping and swallowing the prey.
Minke whales can be found in both coastal and offshore waters of the Atlantic and Pacific Oceans, as well as in the Southern Ocean. They are known for their agile swimming abilities and can reach speeds of up to 20 knots. Although not considered endangered, they are still subject to threats such as entanglement in fishing gear, collisions with ships, and underwater noise pollution from human activities.
The word "Balaenoptera acutorostrata" has a Latin etymology.
The term "Balaenoptera" is derived from the Latin words "balaena" meaning "whale" and "ptera" meaning "wing", referring to the whale's large pectoral fins that resemble wings.
The term "acutorostrata" is also derived from Latin. "Acuto" means "sharp" or "pointed", and "rostrata" means "beaked" or "snouted". Together, "acutorostrata" refers to the sharp or pointed snout of the whale.
So, the etymology of "Balaenoptera acutorostrata" roughly translates to "winged whale with a sharp snout".
