mosquito's anatomy, like all other insects, is astonishing, but he made some mistakes this guy.
he said it has a hundred eyes, the truth it was two eyes, every eye has hundreds of lenses.
He says it has 48 teeth, this is myth it has no teeth. Some web sites still post this wrong info btw.
He talks about hearts and so.... a mosquito like other insects, has no heart, it's too small to need a heart.
He was right that they have thermal receptors, but their power is they can smell and detect the CO2 coming from breathing creatures up to 100 m distance. And in a way he was right about blood cloting, as its saliva like other blood feeding animals will stop the blood from clotting in its trunk. He was also right about the feet.
Regarding other information provides, the 50-50-50 proportions he gave to the blue whale is a bit random.
Regarding spiders, the female will eat the male if the male is much smaller, and it does not eat the children though, they eat each other, this is their first meal. The pider web is the strongest natural material there, but 5 times the steel is pushing it.
regarding stars, he talked about a star which 24billion light years away, other than being untrue, is impossible, as the edge of the universe, which we can't see of course but calculated as 15 billion years away. Until know the furthest "claim" for a distant galaxy is 13 billion years away, although not everyone is convinced. other distances are also wrong, the north star is 430 LY away and not 4billion, as for the Andromeda constellation (chained woman) its made from hundreds of starts each has a different distance , and not of them are close to the distance he mentioned (2 million ly) because they are in our galaxy.
As for gettign to alpha centori, our closest star after the sun, it won't take theoretically 50 million years to get there, but 165,000 year, still impossible to do though with our technology.
and the speed of light is 300,000 km/second not 240,000
The last bit when he wanted to talk about cloning, he said 23 genes, i think he meant chromosomes, no onw knows how many genes we have, maybe over 100,000.
