Can sharks hear?

Its a good question, can sharks hear? They don’t have ears…? Well it is speculated that sharks have a very well-developed hearing sense because it works with the lateral line that enhances and detects vibrations. This makes them good at hearing low vibrations frequencies and finding the position of the noise through using the lateral pores. So they can hear prey that is near. And although they may not have ear lobes they do have ears. These ears are small holes on the sides of the head that leads to the inner ear. The inner ear has 3 chambers and [...]

The Shark Eye…..eye eye Captain

In keeping with the theme of senses, today we’ll take a look at the shark’s eye. A shark’s eye is as advanced as its hunting technique. It consists of two duplex retinas: cones and rods. Cones enable you to see in the colour whereas rods help the eye to adjust to light and dark by dilating and contracting the pupils to allow more or less light in. This allows the shark to see up to 15 meters long. The shark’s eye is made up of the normal elements like a human’s eyes such as the cornea, lens, retina, pupil and [...]

Digestion of a great white shark

Seeing sharks close by gives me butterflies in my stomach (wait… that’s love?), okay then they make my stomach growl (nope, that’s when I’m hungry)… Oh, I got it! Sharks turn my stomach inside out. No! They turn their own stomachs inside out… They can’t actually vomit instead they do something similar to vomiting: gastric eversion. This is where the stomach relaxes and oesophagus contracts to “clean” any indigestible food like licence plates, parasites or bones from the stomach lining. Let’s take a look at how a shark digests its lovely not broken seal prey. The digestive system can be [...]

Muscle and Movement of a great white shark

Muscle and Movement Did you know sharks can fly? Okay, not really… but the microscopic grooves, or riblets, in shark’s skin inspired the construction of an aeroplane. Did you also know there is a material created that is similar to shark skin to prevent algae settling on the hull of ships? And engineers are attempting to integrate it into hospital coatings on surfaces to reduce infections and bacterial growth. A Great White tends to attack from beneath and behind therefore it needs to be fast and stealthy to catch prey. So let’s delve into Mother Nature’s design into an apex [...]

A great white ” nose” best

A great white " nose" best Have you ever wondered how a shark is so accurate and can smell something miles away? Maybe its because it smelled something fishy? Who nose? But let’s take a look at the tip of the issue. Did you know touching a shark’s nose sends them into a trance-like state? Please DO NOT EVER try and touch a shark’s nose – EVER (including in a cage!). Ten fingers, ten toes and smiles are what we want the most. Since we are at Blog number 5 I thought I’d switch it up and talk about the [...]

Let’s Talk About It…Soup fin or Vaalhaai Shark

Let’s Talk About It…Soup fin or Vaalhaai Shark Found in False Bay though not exclusively, as it is rather wide spread in temperate waters, this shark is family of the houndshark and has many names; Tope Shark, Vaalhaai, School Shark and Snapper Shark. It is also sometimes referred to as the Vitamin Shark, as its liver is very high in vitamin A.

Shark Skeleton

Have you ever wondered what the inside of a shark looks like? No? Well I have. Interestingly a shark doesn’t actually have bones or a skeleton- per se. Did you know that, like a tree, you could tell a shark’s age by counting the rings in their bones? And that they aren’t like a normal piece of snoek with thousands of little bones because they do not have true bones like other fish. This is also, why a ray can “flap” like a bird. A shark is in fact made up of a lighter, flexible cartilage that is more elastic [...]

Let’s Talk About It, The Orca

Let’s Talk About It, The Orca   With all the “boo-ha-ha” in Gansbaai, regarding the appearance of 4 Orcas in the bay, which seemed to coincide with the disappearance of the Great White Shark population from the famous Shark Alley, I thought I would take a deeper look into this phenomenon, of course only once the sharks had returned. There seems to be differing beliefs here, some on the side of the Orca, saying they are not responsible for the disappearance of the Great Whites, as they are not a threat and others who believe they are a threat and [...]

Let’s Talk About It…Sandbar Shark

Let’s Talk About It…Sandbar Shark The Sandbar Shark is found in temperate and tropical waters, from the Western Atlantic, between Massachusetts and southern Brazil; in the eastern Atlantic from Portugal to Zaire; and in the Indo-Pacific from South Africa, our very own False Bay and KZN to the Galapagos and from Vietnam to New Caledonia. Also occurring in the Red Sea and Mediterranean, this shark is gorgeous. Not taking anything away from the others, but this little guy is just a stocky, solid shark, makes me think of a Staffie. He gets his name from being blue-greyish brown in colour [...]
