Whales breastfeed their young ones with milk

Just like every other mammals, Whale’s which is considered the biggest animal on earth feed their young ones with breast milk even while inside deep waters.

Surprisingly, mother whale which is also known as “Cow” feed their calves (baby whale) without nipples.

Mother whale do not have nipples, they are only able to release milk to young ones through their ‘mammary slits’- a special folds of skin that enclose the feeding glands. Though researchers are not completely sure how they do it, it is believe that either the calves can curl their tongues into a tube-like shape to fit its mother feeding gland to release milk, or that specialised muscles (mammary silt) actually contract the mammary glands, squeezing milk directly into the calf’s mouth.

The blue whale has the largest mammary glands on Earth, each gland is about 1.5m long in comparison weighs as much as a baby elephant. Blue whale mothers can produce 200 litres of milk per day with a fat content of 35-50%. Such percentage of fat enables a blue whale calf to gain and incredible weight rate of 100kg per day.
