i'm trying to find an answer to your question as far as how they lived. this is the great white i pulled off wiki.
"The great white shark (Carcharodon carcharias), also known as the great white, white pointer, white shark, or white death, is a species of large
lamniform shark which can be found in the coastal surface waters of all the major oceans. The great white shark is mainly known for its size, with
mature individuals growing up to 6.1 m (20 ft) in length and more than 1,900 kg (4,200 lb) in weight. Although some controversial reports
have been published of great white sharks measuring over 7 m (23 ft) and 3,324 kg (7,328 lb) in weight. This shark reaches its maturity around 15
years of age and was previously believed to have a life span of over 30 years. The true lifespan of great white sharks is far longer, now estimated to
be as long as 70 years or more, making it one of the longest lived cartilaginous fish currently known. Male great white sharks take 26 years to
reach sexual maturity, while the females take 33 years to be ready to produce offspring."
as i pointed out and phage was able to answer in my tech absence.. lol. for now only the teeth and jaw bones have been recovered. but scientist have
tried to go by the great whites body and theorize how the Megaladon might have looked. this is from wiki..
"Gottfried and colleagues further estimated the schematics of megalodon's entire skeleton. To support the beast's dentition, its jaws would have
been massive, stouter, and more strongly developed than those of the great white, which possesses a comparatively gracile dentition. The jaws would
have given it a "pig-eyed" profile. Its chondrocranium would have had a blockier and more robust appearance than the great white. Its fins were
proportional to its larger size. Scrutiny of the partially preserved vertebral megalodon specimen from Belgium revealed that C. megalodon had a
higher vertebral count than specimens of any known shark. Only the great white approached it".
Using the above characteristics, Gottfried and colleagues reconstructed the entire skeleton of C. megalodon, which was later put on display at the
Calvert Marine Museum at Solomon's Island, Maryland in the United States. This reconstruction is 11.5 metres (38 ft) long and represents a
young individual. The team stresses that relative and proportional changes in megalodon skeletal features are ontogenetic in nature in comparison to
that of great white, as they occur in great white sharks while growing. Fossil remains of C. megalodon confirm that it had a heavily calcified
skeleton while alive".
they are not sure how it really looked.
