MEGALODON
the popular 2018 movie, "The Meg," pits modern humans against an enormous megalodon sharks, it's actually more than likely that the beast died out before humans even evolved. But it's difficult to pinpoint the exact date that the megalodon went extinct because the fossil record is incomplete.The megalodon, the largest shark in the world's ocean, possessed a streamlined and powerful body that allowed it to effortlessly navigate through water. Its tailfin moved in a side-to-side motion, while it obtained oxygen through gill slits located on both sides of its head.The scientific name, Otodus megalodon, signifies its immense dental structure, as its teeth are nearly three times larger than those of a contemporary great white shark. The fossilized remains of the megalodon shark, including its bones and teeth, provide valuable insights to scientists regarding its characteristics and extinction timeline.Like other elasmobranchs, megalodons have cartilage skeletons, which is a defining feature of this group of fishes. Cartilage is lighter than bone, allowing sharks to stay buoyant and swim long distances with less energy. However, cartilage is difficult to fossilize, so our knowledge about megalodons primarily comes from their teeth, vertebrae, and fossilized feces. The proposed shape of a megalodon is based on the anatomy of living sharks, and recent research suggests that it is closely related to make sharks rather than the Great White. There is much debate in the scientific community regarding the size of the megalodon shark. Based on the size of its teeth, some experts suggest that it could have grown up to 60 feet (18 meters) long, while others believe it may have been closer to 80 feet (25 meters) in length. According to Animal Diversity Web, modern great white sharks can grow up to 20 feet (6 m) in length. The whale shark (Rhincodon types) is even larger, reaching up to 32 feet (9.7 m). The giant oarfish, which is the longest bony fish alive, can reach up to 36 feet (11 m), as reported by the Florida Museum of Natural History.

Impact of climate change
The impacts of climate change on different sectors of society are interconnected. Droughts have the potential to negatively affect food production and human health, while flooding can result in the spread of diseases and cause damages to ecosystems and infrastructure. Furthermore, human health issues can lead to increased mortality rates, impact the availability of food, and limit worker productivity. It is important to note that climate change impacts are pervasive and can be observed in every aspect of our world. However, these impacts are not evenly distributed across the country or the globe. Even within a single community, the effects of climate change can vary between neighborhoods or individuals. This discrepancy is often exacerbated by long-standing socioeconomic inequities, which make underserved groups more vulnerable. These groups typically face higher exposure to hazards and have limited resources to effectively respond to the challenges posed by climate change.

Apologised for doing wrong in English Literature International GCSE exam.
It's unfortunate that a prestigious private girls' school had such an issue with their English Literature International GCSE exam. Such incidents can cause stress and confusion for students. Offering the wrong book for study can be a serious mistake on the part of the school or the exam board responsible for administering the test.
