With full captions explaining the difference between the species, their behaviour and feeding habits, Whales & Dolphins is a vibrant look at these marine mammals in 180 vivid photographs.Whales and dolphins alike are renowned for their intelligent nature and fascinating social rituals. Like us humans, they use vocalisations to communicate. They both have distinctive, streamlined body shapes and propel themselves through water using powerful tails and flippers. These magnificent mammals are frequently described as 'sentinels' of ocean health, providing key insight into marine dynamics and ecosystem quality. Whales are the largest marine mammals belonging to the Cetacea order (whales, dolphins and porpoises). Their incredible size continues to amaze us, the blue whale reaching an astounding 100ft (30.48 metres) and weighing as much as 200 tons. Dolphins, found in both oceans and freshwater, are actually classed as small- toothed whales. They are esteemed around the world for their sleek physical appearance and intriguing sounds used to communicate with each other.
