So snakes are cold blooded but they can live in africa
Several species of snakes have demonstrated the ability to survive in very hot regions including deserts. They are ectothermic animals and can burry themselves in the sand during the day time in such hot regions to avoid the immense heat. So it is not a matter of surprise for us, if they can be found in Africa.
and by the way don't you think after a million years the climate could change so that currently warm water regions were once cold areas and like I said , a snake is cold blooded, but they live in africa right?
The world of Megalodon was very different from the one in which we thrive.
The climatic conditions and the oceans were noticeably warmer during the Miocene epoch, then they are today. The Ice Ages of Pliocene and Pliestocene periods have immensly changed the geological and climatic conditions of the world and the oceans have cooled down a lot as the result and many warm water regions have vanished.
Hence, Megalodon thrived in the warm waters around the world.
However I would like to point out that all marine animals have certain limits of tolerance for temperatures. The Warm blooded or endothermic creatures have greater tolerance limits of temperatures than the Cold blooded or poikilothermic creatures. The endothermic creatures can adjust within the major changes in the temperatures with much better efficiency. However some very large fish can be gigantothermic and can exhibit greater level of tolerance of temperatures than the pure poikilothermic fish.
Megalodon might have been able to tolerate the cold waters but within specific limits. It was not able to tolerate the water temperature in polar regions however at the end of pliocene epoch.
And I did not say that Megaladons and Great whites arent close relatives, read Capeo's earlier post quoting me and he said that Megaladons and Great whites arent currently thought to be related
Capeo's view point is very formal in nature. In the old times, it was believed that the Megalodon was the direct prehistoric ancestor of the Great White Shark, but this was proven to be not true in the later years.
Though Great White Shark and Megalodon are still distant cousins in the bigger picture. The anatomical similarities between these two sharks cannot be ignored, so for this reason the Great White Shark is termed as the closest living relative of Megalodon.
And by the way, don't you think that Megaladons cant be like snakes , eat a BIG nice meal of fatty animal and stay dormant for almost a week that would cut down on the energy output you know.
Megalodon had massive metabolic requirements. To sustain its immense size, it had to eat a lot. Such a creature may not be able to stay dormant for an entire week without eating any food.
in fact, i dont know if any sharks are deep sea predators.
Some sharks are deep sea predators or can hunt in deep waters. Pacific Sleeper Shark is one such example.
