The belly, or ventral, part of the body, is white. This makes it difficult to see the sharks from below, with sunlight shining in around them. […]

Sharks don’t use a swim bladder like most fish do to maintain buoyancy but use their liver, fins and cartilaginous structure instead. To maintain buoyancy they use these three mechanisms; their sizeable livers, filled with an oil that contains squalene; their fins; their cartilaginous skeletons. How do sharks maintain neutral buoyancy? Put the sharks in […]

The great white shark is responsible for the most unprovoked attacks of any other shark in the world, according to the Florida Museum.

When the shark is gently turned on their back, it’s thought to disorientate them, causing them to enter the state. The shark’s muscles relax and their breathing becomes deep and rhythmic.

Why does flipping a shark paralyze it? When […]

A mako shark off the coast of […]

Jet skis can outrun sharks as they are quicker than the Mako, which is the fastest shark on the planet. However, given the open design of a jet ski, though, you may not be as safe as you think… especially if you happen to fall off the watercraft and attempt to outswim a shark. Can […]

It is not uncommon for sharks to feast on whale carcasses. While the species are infamous for being apex predators, dead whales present an opportunity for them to scavenge an easy meal rich in energy. Sharks are unlikely to attack fully grown, live whales on a regular basis because of their size. Do sharks eat […]

Since tiger sharks are apex predators, they do not have many natural predators themselves. The only known predator of the tiger shark is the orca.
