Recent research indicates that shark teeth, some of nature’s most efficient cutting tools, are increasingly vulnerable to environmental changes in ocean chemistry. A 2025 study published in Frontiers in Marine Science investigates how shifting ocean conditions might compromise the structural integrity of predator teeth, providing critical insights into the ecological consequences of global carbon emissions. Ocean Acidification And Its Impact …

The ocean is getting more acidic, and it could affect sharks’ teeth
Facebook Tweet Email Link How will the climate crisis affect one of the ocean’s fiercest predators? New research published Wednesday has examined what might happen to sharks’ highly specialized, flesh-cutting teeth. As carbon emissions increase, the ocean is absorbing more carbon dioxide from the atmosphere, lowering pH levels and making seawater more acidic, a process that can affect many ocean …

Sharks without teeth might sound like the stuff of dreams to swimmers and surfers. Now a new study has found that ocean acidification could leave the apex predators without their critical survival weapon. Shark jaws carry several rows of teeth and new ones quickly push forward to replace losses. However, rapidly acidifying oceans are damaging shark teeth and could speed …

SCARBOROUGH, Maine (AP) — New data shows that great white sharks are spending more time in the chilly waters off New England and Canada’s Atlantic coast. That means boaters, beachgoers and fishermen who spend time in the northern waters are learning to live with the predators made famous by the movie “Jaws” 50 years ago. Sightings of the sharks are …

White sharks exhibit stark differences between the DNA in their nuclei and the DNA in their mitochondria. Until now, scientists have pointed to the migration patterns of great whites to explain these differences. Scientists tested this theory in a new study by analyzing genetic differences between global white shark populations. In doing so, they discovered that great whites were restricted …

The genes of great white sharks defy scientific explanation. An animal’s genome can be deeply revealing, but ever since researchers started decoding great white shark (Carcharodon carcharias) DNA more than 20 years ago, their discoveries have raised more questions than answers. In 2024, a study confirmed that, contrary to common thought, this fierce ocean predator does not belong to a …

Great white sharks are magnificent creatures and an icon among sea predators. But despite their fame across the world, inspiring stories, books, films, games, and more, there’s still a great deal we do not know about them. In an effort to answer a long-running question surrounding their populations, scientists have stumbled into a deeper mystery concerning their genetics that has …
Read More »Why do sharks freeze when flipped upside down?
Sharks can be formidable predators, but when they’re flipped upside down, many species enter a trance-like state, known as tonic immobility, and are as helpless as a beetle on its back. Tonic immobility is “as close to hypnotising a shark as you can get!” Joel Gayford, a doctoral candidate of marine ecology at James Cook University in Australia, told Live …
