Hi all
Well I am back in South Africa I can’t believe my luck. Earlier this year I had hoped to see great white sharks. For some reason only a few sharks returned to seal island and so I did not see any before I had to return to England.
However, this changed very quickly and I got a call (and invitation) from Chris & Monique Fallows, who are naturalists and Shark Lovers (!). They would to be my hosts and guides.
I asked Monique what an ecosystem was. She said that the plants and animals that are found in a particular location are referred to as an ecosystem. These plants and animals depend on each other to survive. This balance between the plants and animals is a delicate balance and can easily be damaged by some human activities.
I asked Monique why they were called Apex Shark Expeditions. She explained that the great white shark is an Apex Predator, which means no other predators hunt and eat great white sharks. So I wondered why the oceans were not full of great white sharks if nothing else eats them.
Monique explained that great white sharks help keep the other animals in the ecosystem in balance. While nothing eats the great white sharks, their numbers are kept in balance by the rest of the ecosystem. The amount of sharks will not be greater than the amount of food that is available to them. No wonder the oceans are in so much trouble when ecosystems are so delicately balanced.
I asked Monique what wildlife we might see, but she said she did not want to spoil the surprise. When at sea you never know what you will encounter. Chris and Monique said that everything in nature exists together and there are many unique relationships, so it is always a good idea to go to sea with your eyes wide open! You never know what you might see.
Monique said we would be leaving very early in the morning so I left them both planning tomorrows trip and went bed.
Bye for now
