( Source ) Hammerhead sharks have a strange behavior of  swimming sideways . This type of swimming proves the most energy-efficient for them. They use nearly 10% less energy by swimming sideways instead of upright swimming. ( Source ) Hammerhead sharks initially appeared on  earth  around  20 million years  ago. These sharks live for around 30 years on average. ( Source ) The visual field of each eye of the hammerhead shark is 180 degrees. Their eyes also have excellent depth perception.

Scientists   initially discovered  dinosaur  fossils  in Antarctica in 1990-91. The place of discovery of these dinosaur fossils is the central Trans-Antarctic Mountains. ( Source ) The  fossilized remains  of prehistoric freshwater amphibians and reptiles have also been found in TAM. The most extensive  coal-bearing deposits  in Antarctica are located in the Transantarctic Mountains. These coal deposits are of Permian and Triassic age and extend over an area of 2,500 km. ( Source ) The width of TAM is from the Ross Sea in the south to the Weddell Sea in the north. This mountain range is the most prominent dividing point of the  continent  due to its length and elevation.  Width of TAM is from Ross Sea to Weddell Sea The Transantarctic Mountains are the longest rift shoulder (elevated areas around rifts) in the
