More Questions Than Answers: Recent Australia Shark Bite

The total number of unprovoked shark bites worldwide remains extremely low. But, in the unfortunate event when an incident does occur, it's devastating for all those involved. And raises many of the same questions. Dr Blake Chapman explains the huge number of factors that must be considered when trying to answer the ultimate question, ‘why did this happen?'

Fossil Upends Theory of How Shark Skeletons Evolved

7 September

A 410-million year old fossilized fish skull (made of bone) has been a real head scratcher for scientists. It's long been theorised that sharks, and their skeleton of cartilage, evolved before bony fish. But this discovery is making scientists rethink how these two groups of fish evolved.

How Massive was the Meg? 

3 September

We always knew the Megalodon was well…mega! But before we only had an estimation of its length based off fossil teeth and mathematical comparisons to the White Shark. Now scientists have determined the size of different body parts of this prehistoric shark, including a dorsal fin that's as tall as a human!

Using comparisons to five species of shark still around today, scientists have been able to estimate the body dimensions of a 16m Megalodon. The head alone measures 4.65m. Mega indeed!

Drone Footage Captures ‘Synchronised’ Basking Shark Behaviour

Researchers were treated to an incredible encounter when they captured drone footage of nine circling Basking Sharks off County Clare, Ireland. The Basking Shark’s behaviour was described as ‘methodical, orchestrated, as if they were doing synchronised swimming’. And has been linked to courtship.

How Some Animals Have ‘Virgin Births’: Parthenogenesis Explained

Parthenogenesis. It's a big word. But essentially means, animals producing offspring without mating. This concept may seem odd, even impossible. But it's been proved possible for a range of different species, including Zebra Sharks. This feature in National Geographic explains more.

Social Media: A Valuable Tool to Inform Shark Conservation in Greece

Its risky business being a shark in the Mediterranean. Over half of the sharks found in these waters face an increased risk of extinction. Low population numbers mean species are hard to detect through usual methods. Social media is becoming an increasingly valuable tool to collect and communicate important information. Helping conserve vulnerable species. From a study of 116 social media posts carried out in Greece, researchers found that over 60% of the posts referred to threatened species.

New Study Reveals More About the Life History of the Goblin Shark

Aging the weird but wonderful Goblin Shark requires unconventional methods. Using a technique that involves staining sections of the spine, we now know that this deep-water shark matures at ~16 years and can live up to 60 years!
