Behemoths of the ancient past…and future?

One thing that many known prehistoric creatures have in common - and the thing that most people find fearsome - is that a lot of them were huge. Everyone knows about the gigantism of T-rex, Diplodocus, and Megalodon. But there were also ground sloths the size of modern-day elephants, dragonflies the size of hawks, and cockroaches the size of domestic cats (!)

closely related to sharks but with long, flat bodies and wing-like pectoral fins, mobula rays are ideally suited to swooping through the water - here off the gulf of california - yet seem equally at home in the air, so much so that they have earned the name “flying rays”. mobula rays can reach heights of more than two metres, remaining airborne for several seconds. 

mobula rays are quite elusive and difficult to study, so biologists are not quite sure why they jump out of the water. theories vary from a means of communication, to a mating ritual (though both males and females jump), or as a way to shed themselves of parasites. they could also be jumping as a way of better corralling their pray, as seen with them swimming in a circular formation. 

what is known about mobula rays is that they reach sexual maturity late and their investment in their offspring is more akin to mammals than other fishes, usually producing just a single pup after long pregnancies, all of which makes them extremely vulnerable to commercial fishing, especially as a species that likes to come together in large groups.

The name “hippopotamus” comes from a Greek word meaning “water horse” or “river horse.” But hippos are not related to horses at all—in fact, their closest living relatives may be pigs or whales and dolphins! (photo: Peter Csanadi)
