Whales are a large group of marine organisms, even at birth, their size is relatively large. Its body length may be between 6 and 8 meters, and its weight can reach several tons. Specifically, the size of different whales is different, so their specific size is different when they are born. For example, the blue whale, the largest whale, has a body length of about 7.5 meters and a weight of about 6 tons, and its growth rate is relatively fast.

1. how big are whales when they are born

Whales are a relatively large class of marine life, even when they are born, their size is relatively large. Generally speaking, their body length can be 6-8 meters, and their weight can reach several tons. Specifically, this value is not certain, because whales themselves have many different species, the size of these different species of whales will be more different, so the size of newborn whales is also more different.

For example, when the largest blue whale calf is born, its body length will be about 7.5 meters and its weight will be about 6 tons. Blue whales go through a period of lactation after birth. During this time, the growth rate of blue whales is very fast, in the first 24 hours, their weight can increase by 100 kilograms. After a few months of lactation, the weight of small blue whales can reach about 23 tons, and their body length can reach about 16 meters, when they are already relatively large. After lactation, baby blue whales may try to hunt on their own.

2. how many kilograms of whales are born

As mentioned above, even newborn whales are relatively large in size and heavy in weight. Specifically, the weight of different species of whales at birth is different, but most of the calves can weigh several tons. For example, the blue whale described above may weigh about 6 tons at birth. During lactation, they grow rapidly, gaining 100 kilograms in the first 24 hours.
