How much does meglodon shark weigh in pounds?
A consertative estimate of a medium sized C. megalodon, with 16 metres in total lenght, would be aprox. 50 tonnes.
A larger specimen with 20 metres would probably weight more than 100 tonnes.
But this is, at best, an educated guess.
We DON'T KNOW how large could be the largest specimens.
We DON'T KNOW the body structure of C. megalodon.
We DON'T KNOW if megalodon belonged to the genus Carcharodon, and was a bulkier version of a great white (Carcharodon carcharias), or if it belonged to the genus Carcharocles, and in this case it could well be a gigantic Mako shark.
Do sharks eat their way out of the womb?
I don't believe so, although in one species of shark, an unborn shark will set about killing it's unborn siblings and gradually eating their remains until it is born. All I can say about this is that the mother must have an amazing immune system not to get ill from the rotting remains within her. Some species of sharks are born encased in eggs.
Are sharks the most dangerous animals in the world?
Depends on the species.
The two biggest, the basking shark and the whale shark, are filter feeders and can't hurt humans unless they ram or swipe at you.
Many are too small to be a realistic threat.
Sharks will eat a dead animal, and kill if necessary. But shark attacks to humans are quite rare. If you are swimming where sharks are, the shark might mistake you for a seal, a dolphin or some other animal. In fact, it is extremely rare for a shark to attack a human knowing what their victim is. Sharks can smell blood from miles away, and are easily attracted to it.

I am afraid it is due to the realease of the movie "Jaws" that enforeced others to fear them. Just remember, Shark Safety is important.

What shark has jumped out of water higher?
No. Bull sharks do not jump out of the water normally. They may show up on the surface while hunting or even rise a part of their body above water level. However, they cannot jump like dolphins or whales.
The swim bladder can fill by gulping air at the surface, this enables the fish to float or empty by loosing air from the swim bladder through a pneumatic duct (a pneumatic duct is an internal gas filled organ) connected to the oesophagus, this enables the fish to sink.
got this answer from another person. i really hope that it is right
Mantids eat various creatures. But they usually eat creatures which are much smaller then them but in some cases the mantid will try to eat creatures the same size or even bigger.
It has also been know that a female Mantid will eat the male after mating. But this will only occur if the female mantis is hungry.
Personally i would recommend: Micro Crickets.
