A blue whale's aorta is so large a human can fit inside
|
view preview
Aside from claiming the title of the largest animal known to have ever lived, the blue whale ( Balaenoptera musculus) possesses a heart big enough to house a human. The heart of an average sized blue whale weighs 180 kg (400 lb) and is also the largest known in any animal. During the first seven months of its life, a blue whale calf drinks approximately 380 litres (100 US gal) of milk every day. Blue whale calves gain weight quickly, as much as 90 kilograms (200 lb) every 24 hours. Even at birth, they weigh up to 2,700 kilograms (6,000 lb) - the same as a fully grown hippopotamus. Blue whales have proportionally small brains, only about 6.92 kilograms (15.26 lb), about 0.007% of its body weight, although with a highly convoluted cerebral cor ...

Ever seen an albino turtle? Check this out
|
view preview
This rare albino green sea turtle just hatched on a beach in Queensland, Australia. Albinism is the congenital absence of any pigmentation or coloration in a person, animal or plant, resulting in white hair and pink eyes in mammals. Unfortunately, albinism can reduce the survivability of an animal, and the same can be said about this baby turtle. For example, it has been suggested that albino alligators have an average survival span of only 24 hours due to the lack of protection from UV and their lack of camouflage to avoid predators. ...

This baby fish will grow up to be one of the fastest fish in the sea
|
view preview
While it may look small now, this baby swordfish ( Xiphias gladius) grows fast and can reach 14 feet in length and weigh up to 1,200 pounds as an adult. They are found in the Atlantic, Pacific and Indian oceans and sometimes cold waters, including the Mediterranean Sea, the Sea of Marmara, the Black Sea, and the Sea of Azov. They are highly migratory, moving to warmer waters in the winter and cooler waters in the summer. While they are not at the top of the food chain, it is not a fish to be messed with; apparently, even sharks are wary of them! ...

Ever seen a hairy rhinoceros?
|
view preview
Sumatran rhinoceroses are believed to be the oldest surviving rhino species - and the closest surviving relative of woolly rhinos, which died off 10 000 years ago. Apart from being the smallest rhino, they're completely covered in hair (shown above), especially the young ones. Their hair is very soft and they also sound like humpback whales when you hear them, making them incredibly cute.

This is not a dinosaur
|
view preview
This is a baby kangaroo and, no, scientists have not cloned a dinosaur! April Fools came early this year, with some people falling for a hoax over the weekend that claimed this image of a baby kangaroo is actually a cloned Apatosaurus. Australian animals don't look that weird, do they?

Tiny octopus hatchling
|
view preview
This tiny octopus hatchling looks like it wants to pick a fight with the eraser! This is a baby Caribbean pygmy octopus that was born at the Mote Marine Laboratory Aquarium in Florida in March. As you can see, it was extremely tiny at only a day old when this image was taken, but even when fully grown it will only be the size of a dollar coin.

Breast milk varies depending on gender
|
view preview
![](https://biology-forums.com/gallery/47/13_06_09_13_9_10_13_134581074.jpeg) Studies in humans, monkeys and other mammals have found that mothers have different breast milk 'recipes' depending on the sex of their newborn – boys often get milk that's richer in fat or protein, while baby girls get higher calcium levels and more milk overall. These findings could help improve baby milk formulas.

The researchers gave pregnant women a recording of several spoken variations of the made-up word "tatata" to play daily during their last trimester. When tested using EEG sensors after birth, their infants' brains recognised the words and its variations, while the control group did not.

Abortion is a tough lemon to swallow

view preview
Take a good look at this premature child. It's hard to deny that it isn't a fully formed human being, though in some parts of the world, abortions at the second and third trimester are perfectly legal ![Undecided](https://biology-forums.com/Smileys/default/1f615.png) Thoughts are welcome.
