Meet the blue whale for kids
The blue whale for kids is the largest animal on Earth. Picture a creature longer than two school buses, reaching lengths of up to 110 feet and weighing as much as 330,000 pounds. Its scientific name is Balaenoptera musculus. Born in warm seas, a calf drinks rich milk and grows fast.
Also, blue whales feed on tiny krill with baleen plates. They migrate thousands of miles and sing deep, low songs that travel far. These gentle giants help keep oceans healthy.
Size and body of the blue whale
Adults commonly reach about 24 to 27 meters long. Some nearly touch 30 meters. They can weigh around 150 to 200 tonnes. Their skin looks bluish grey with light mottles. A small dorsal fin sits far back on a broad flat head.
- Heart similar in size to a small car
- Tongue can weigh as much as an elephant
- Throat grooves allow the mouth to balloon when feeding
These massive animals move slowly and with purpose. They are truly enormous and wonderfully calm.
How they eat
Blue whales are baleen whales. Instead of teeth, they have baleen plates. They eat tiny shrimp-like animals called krill.
A whale takes a huge gulp of water. Then it pushes water out through the baleen to trap krill. Throat grooves expand and the whale swallows a great meal. During peak feeding, a whale may consume up to 6 tons of krill per day. That is a lot of tiny food for a very big body.
Life cycle and family
Gestation lasts about 10 to 12 months. Calves are born in warmer waters at roughly six to seven meters long. They nurse on fatty milk and grow quickly, gaining approximately 200 pounds daily during their first year. Young whales join seasonal migrations from cool feeding grounds to warmer breeding waters.
Blue whales can live many decades, often to 70 years or more. Families are quiet and slow moving. Calves learn songs and routes from older whales.
Behavior, songs and why they matter
Blue whales sing very low calls. Some calls sit below human hearing. However, these calls travel far underwater. They help whales find one another and navigate the ocean. In fact, blue whales are among the loudest animals on the planet, with their vocalizations reaching up to 188 decibels, louder than a jet engine.
Blue whales also move nutrients from deep water to the surface. This whale pump supports plankton and the entire food web. Sadly, whaling once cut their numbers severely. Today, the global blue whale population is estimated to be between 10,000 and 25,000 individuals, classifying them as an endangered species, and they face threats like ship strikes, fishing entanglement, noise pollution, and climate change.
