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).
They are called killer whales because they attack and consume whales or other large prey such as seals and sea lions. General description: Adult killer whales generally grow to a length of approximately 27 feet (8.2 m). Females grow to an average length of about 23 feet (7 m).
