Which Animal Produces the Biggest Baby?


The blue whale is the animal that produces the biggest offspring. According to National Geographic, baby blue whale calves emerge from their mothers’ wombs with a weight around 3 tons and a length of 25 feet.

During the first year of their lives, the babies gain about 200 pounds each day in weight. The blue whale is also the largest adult animal on Earth, with the adult size measuring up to 100 feet long. In addition, it can weigh over 200 tons. Blue whales gain weight rapidly due to a diet composed primarily of krill. In some cases, blue whales can consume up to 4 tons of krill per day. According to the World Wildlife Fund, a blue whale can eat 40 million krill per day.
