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.
Baleen whales have two blowholes positioned in a V-shape, while toothed whales have only one blowhole. [6] The blowhole of a sperm whale , a toothed whale, is located left of centre in the frontal area of the snout, and is actually its left nostril, while the right nostril lacks an opening to the surface and its nasal passage is otherwise well ...
Baleen whales range in size from the 6 m (20 ft) and 3,000 kg (6,600 lb) pygmy right whale to the 31 m (102 ft) and 190 t (210 short tons) blue whale. When swimming, baleen whales use their forelimb flippers in a wing-like manner similar to penguins and sea turtles for locomotion and steering, while using their tail fluke to propel themselves ...

An underwater photographer who got up close and personal with a massive blue whale says the experience left him feeling awestruck — and incredibly small. Stunning photo shows diver's close ...
Work of breathing is increased by increased density of the breathing gas, artifacts of the breathing apparatus, and hydrostatic pressure variations due to posture in the water. The underwater environment also affects sensory input, which can impact on safety and the ability to function effectively at depth.
