Vegetable is a culinary term. Its definition has no scientific value and is somewhat arbitrary and subjective. All parts of herbaceous plants eaten as food by humans, whole or in part, are generally considered vegetables. Mushrooms, though belonging to the biological kingdom, fungi, are also commonly considered vegetables. Since vegetable is not a botanical term, there is no contradiction in referring to a plant part as a fruit while also being considered a vegetable.
Killer whales are the largest extant members of the dolphin family. Males typically range from 6 to 8 metres (20 to 26 ft) long and weigh in excess of 6 tonnes (5.9 long tons; 6.6 short tons).
The Blue Whaleâs tongue weighs around 2.7 metric tons (5,952 pounds), about the size of an average Asian Elephant and its heart weighs about 600 kg (1,300 lb) and is the largest known in any animal. Not only is the heart similar size to a mini-cooper car but also comparable in weight.
