certain species have developed traits that allowed them to dominate their habitats. To understand the role of apex predators, we need to discuss the flow of energy through a food chain. This concept is encapsulated in the energy pyramid. ...

Whales have varying conservation statuses depending on species. Of cetacean species, 7 arevulnerable, 11 areendangered, and 5 arecritically endangered. Species of whales that are endangered include thekiller whale, Mediterraneansperm whale, andblue whale. Killer whales are apex predators, meaning no o...
Great whites are called apex predators(捕食者)because they are at the top of the food chain. They have no predators and aren’t that picky about what they eat. Great whites are known to eat fish, squid, other sharks, otters, turtles, dolphins, whales, seals, and sea lions. 【3】 ....
The reintroduction of apex predators is often met with disbelief and dismissal by the public but in most cases, it can be beneficial for both the ecosystem and the economy of the proposed area. This paper starts by setting a definition and presenting necessary background knowledge on rewilding....
These values were used to place large-bodied theropod species into generalized mass bins and identify time spans where apex predators achieved relative gigantism (43,500 kg). We recognize that mass extrapolation adds additional uncertainty to size estimates over FL alone, specifically among clades ...

Allosauroid theropods were a diverse and widespread radiation of Jurassic–Cretaceous megapredators. Achieving some of the largest body sizes among theropod dinosaurs, these colossal hunters dominated terrestrial ecosystems until a faunal turnover redefi

Today sharks should be the apex predators of the ocean - 如今,鲨鱼应该是海洋的顶级捕食者, the top predator that hunts and eats other animals but has no natural predator of its own. 它是猎食其他动物的顶级捕食者,还没有天敌。 Instead, over 100 million sharks are caught and killed each year...
