| موضوع: Top 7 Weirdest Species of Shark Top 7 Weirdest Species of Shark Top 7 Weirdest Species of Shark Our planet’s oceans are crazy, and not just because saltwater takes up about 70% of Earth’s entire surface, but also because there are millions, if not billions, of yet undiscovered sea creatures lurking in the depths. If you think about it, we know more about our galaxy and the infinite Universe, than the underwater world in our own back yard. That in itself is mind blowing. Anyway, what I’m trying to say is that our oceans are dope, and I needed a way to segue into the topic of sharks. Did you know that sharks have been around for over 450 million years, and that if I showed you their distant relative from 370 million years ago, you’d be able to tell it’s a shark? There are over 470 species of sharks splashing around in Earth’s oceans, and most of them look a lot like their prehistoric ancestors. Of course, not all of them are dangerous to humans, but there really are some weird specimens! Here are some of the most bizarre sharks I’ve ever seen (on paper). 1. Megamouth shark If you couldn’t tell by the name, this shark has a really big mouth. Throw in those thick lips and you’ll get the most handsome sharkboy in the sea. But don’t be afraid of this big doofus, as it feeds mostly on plankton. These giants grow around 13-16 ft (4-5 m) and weigh around 2,600 lb (1,200 kg). And that’s pretty much all we know about them, since they were only discovered 40 years ago, and we’ve seen less than 60 specimens. 2. Greenland shark Again, if it’s a shark, it doesn’t automatically mean they’re all apex predators who will attack anything that moves, some species, like the Greenland shark, prefer to swim around at 1 mph (1.6 kmh) or slower, making it the slowest shark in the world. There’s still a mystery surrounding this shark: what does it eat? Marine biologists have found seals, eels, and other animals much faster than our slowpoke, so… what gives? الموضوعالأصلي : Top 7 Weirdest Species of Shark // المصدر : ممنتديات جواهر ستار التعليمية //الكاتب: ام رحاب
