Balaenoptera sibbaldii Sars 1875. The blue whale (Balaenoptera musculus) is a marine mammal and a baleen whale. Reaching a maximum confirmed length of 29.9 m (98 ft) and weighing up to 199 t (196 long tons; 219 short tons), it is the largest animal known ever to have existed. [a] The blue whale's long and slender body can be of various shades ...
Whales are vulnerable to entanglement in fishing gear and collisions with large ships, and scientists have said both threats are made more severe by warming waters because ocean changes cause ...
Despite the large potential impacts of ocean warming on marine mammals, the global vulnerability of marine mammals to global warming is still poorly understood. [109] Marine mammals have evolved to live in oceans, but climate change is affecting their natural habitat.
The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of all the Earth's species with extinction even in the absence of the other four factors, while if the warming reached 4.3 °C (7.7 °F), 16% of the Earth's species would be threatened with extinction.
The blue whale was not the only marine life passengers saw on the trip. Laurino said they observed about 20 fin whales, pilot whales, several dolphin species, a manta ray that breached the surface ...

The decline of global whale populations Blue whale populations have declined dramatically due to unregulated commercial whaling, putting them at risk of extinction.. Prior to the setting up of the IWC in 1946, unregulated whaling had depleted a number of whale populations to a significant extent, and several whales species were severely endangered.
