Marine wildlife – the Fishes

We recently earned our Open Water Diving certification, which allows us to explore the marine wildlife more in detail. It is the beginning of a long journey to discover the secrets of a vast space, almost 72% of our planet being water! The Ocean is producing 85% of the planet’s oxygen, which links us all directly or indirectly to it! We first learned during the course to respect the Ocean as an ecosystem, as it remains today an extremely important source of life, specifically because it is home for many of the first links in the Earth’s food supply chain, photosynthesis in plans creating oxygen in the oceans just as it does on land (estimated that plant production in oceans may be 10 times more than on land), and this initiates the process of creating organic nutrients which serve to feed more complex organisms, which in turn are fed by larger organisms, and so on… Animal waste and plant and animal decomposition complete the food cycle by replenishing the sea’s basic nutrients and starting the chain of life all over again. One of the most exciting things about exploring the underwater world is that here are less people, as my girlfriend and diving buddy answer when asked, which is true judging by the fact that the marine wildlife has not yet learned to fear us and so they don’t avoid contact with us…yet.

We will keep you posted on our journeys by the means of this blog, but first I would like to recommend an excellent new book I was reading, to learn more about the fishes, one of most diverse, misunderstood and under-appreciated (unless grilled on a plate) of the wildlife species, yet one of the most explored by humans today! Jonathan Balcombe, a life long passionate, ethologist and activist, through his book What a fish knows does and excellent job building the case on the beauty and intelligence of the fishes, their superbly adaptive features making them masters of their environment, but also on the immense pressure on their environment as well as the dangers of the ways we humans irresponsibly chase with ever evolving technology the last remaining half of once thought “unlimited” supply of food on the bottoms of the oceans, and the pain caused by the existing methods of fish exploitation today, understanding what it means to be a fish in a today’s human world! (some quotes from the book in the Facts section).

What a fish knows

Famous related quotes by Jacques Cousteau, one of the early fathers of modern day diving science (“oceanographic technician”, as he liked to refer to himself), as well as one great environmentalist and naturalist:

“From birth, man carries the weight of gravity on his shoulders. He is bolted to Earth. But man has only to sink beneath the surface and he is free”

“The sea, the great unifier, is man’s only hope. Now, as never before, the old phrase has a literal meaning: We are all in the same boat.”

“The happiness of the bee and the dolphin is to exist. For man it is to know that and to wonder at it”

“We forget that the water cycle and the life cycle are one!”

Jean-Michel Cousteau: “Protect the ocean and you protect yourself!”
