Fossilized teeth are most of the remains we have today of the megalodon, which makes it hard to figure out what it looked like or how it lived. But now, scientists have used those teeth to estimate the ancient shark’s body temperature, and found it was… Continue reading Megalodon was warm-blooded – and that might have been its downfall
Researchers at the University of Hawai’i at Mānoa have made a surprising first discovery: scalloped hammerhead sharks hold their breath like air-breathing marine mammals when they deep dive into cold waters to feed. The finding has improved our underst… Continue reading Hammerheads hold their breath to keep warm when deep-diving for food
The majority of shark species are threatened with extinction, so it’s crucial to protect the “pupping” areas where females give birth to live young. A new satellite-linked device, known as the BAT, lets scientists know the locations of those areas.Cont… Continue reading Device uses a BAT signal to show where sharks are giving birth
It’s a sad fact that threatened species of sharks are routinely caught on fishing lines intended for other types of fish. A new device could help change that, by harmlessly scaring sharks away from baited hooks via pulses of electricity.Continue Readin… Continue reading Device generates electrical fields to keep sharks away from fish hooks
Back in July, we heard how orcas were hunting great white sharks in South Africa, scaring the fish away from certain regions. While scientists were basing their findings on examinations of shark carcasses, they’ve now gained new insights by analyzing a… Continue reading Scientists scrutinize new video of orcas hunting great white sharks
Even though the plankton-eating basking shark is the world’s second-largest fish, much of its life has eluded observation. Now, however, researchers have determined that the usually solitary animals find mates by meeting up and circling around one anot… Continue reading Basking sharks found to choose mates by swimming in giant circles
By combining cutting-edge digital modeling with analysis of a rare, one-of-a-kind fossil, scientists have pieced together the first 3D reconstruction of the Megadolon, the largest shark to ever live. From this new 3D model the scientists were able to g… Continue reading 3D model suggests ancient Megadolon could eat an orca in just five bites
Although great white sharks have few natural enemies, orcas have been known to prey on them. A new study now shows that due to attacks by just two orcas, great whites are staying away from parts of South Africa.Continue ReadingCategory: Biology, Scienc… Continue reading Study suggests orca attacks are scaring away great white sharks
A team led by Jeremy McCormack at the Max Planck Institute for Evolutionary Anthropology has found evidence that competition with great white sharks may have contributed to the extinction of the megalodon, the largest shark that ever lived.Continue Rea… Continue reading Competition with great whites may have led to megalodon extinction
Although it’s not a hard and fast rule, marine animals that live in cold climates tend to grow larger than their warm-water counterparts. According to a new study, such may have even been the case with everyone’s favorite prehistoric shark, the megalod… Continue reading Cold waters may have produced the largest megalodon sharks
