Great White Shark Evolutionary Senses
Human beings have come a long way from the days of believing that animals are non-sentient, unintelligent and far below the evolutionary scale of modern man. The deeper we investigate the abundant animal life on our planet, so the perceived gap between the sentience of man and megafauna closes, as we discover that beyond the ability to communicate via verbal syllables, we are not that different from the creatures we share our world with.
Fish have Feelings too
Science has proven that fish, contrary to popular belief, do in fact feel pain. Neurobiological scientists studying the biology of various fish species have discovered that fish produce pain relieving neurotransmitters – the only possible reason that a nervous system of any animal would produce these endorphins, is for pain relief.
Our life-giving Ocean
The Great White Shark has evolved over 400 million years to be the guardian apex predator of our oceans. Tasked with keeping fish populations in check and healthy – this constant inherent monitoring of our oceans has a cascading effect that benefits even the tiniest algae blooms, at the very bottom of the food chain, that ultimately contribute more life-giving oxygen into our atmosphere, than the entire Amazon Rainforest.

Great White Shark Super Senses
The Great White Shark anatomy is geared for hunting through finely tuned senses of smell, hearing, touch, taste, sight and electromagnetism. Working together, these highly developed senses make Carcharodon Carcharias deeply attuned to its oceanic environment.
The Great White Shark’s brain has evolved to be able to outwit prey, such as fast-moving seals and dolphins, that are well known for their incredible agility and intelligence.
Great White Shark Eyes & Nose
The most powerful sense of the Great White Shark is its sense of smell. Their olfactory bulb is believed to be the largest of any shark species, and they can detect even a single drop of blood in 10 billion drops of water.
The Great White Shark’s ears can hardly be seen just behind their eyes, but they are made up of cells that can detect the tiniest vibration in the water. A small ‘ear stone’ that responds to the earth’s gravity, allows the Great White Shark to know its orientation in the water while hunting.
The Great White Shark’s eyes are small in comparison to their body, but they are still a powerful aid to hunting, with a specialized retina that is divided into day vision and night vision enabling them to hunt in dark, murky waters. They have also evolved the ability to protect their eyes from attacks from their prey by rolling them back into their sockets when threatened.
Carcharodon Carcharias Electromagnetic Abilities
The most incredible sense of the Great White Shark is their ability to sense electromagnetic fields. This ‘magic-like’ ability is called ‘electro-reception’ and allows them to navigate through the open ocean by following the map of the earth’s magnetic fields within the earth’s crust. The organ that gives the magnificent Great White Shark this ability, is called the Ampullae of Lorenzi, tiny jelly filled pores that can pick up on the power and direction of electrical currents.
This formidable apex predator’s sense of touch is enhanced by a sensory structure that runs along the length of its torpedo shaped body called the ‘Lateral Line’. This enables them to perceive the tiniest vibrations in the water given off by prey.

Shark & Marine Research Institute
Our Research Institute, Shark & Marine Research Institute was founded to conduct essential research in collaboration with our Government and Universities to help gain a better understanding of the threats facing our vulnerable shark populations, so that the powers that be can make better management decisions that will preserve our incredible sharks for future generations to come.
