It's All A Croc - Looks Can Be Deceiving In The Open Water

Open water swimmers dislike all kinds of jellyfish and they rightly fear sharks and sea snakes, and some even whales if they get too close.

And in others areas in the open water swimming world, open water swimmers have to be aware of orcas, leopard seals and crocodiles.

When an open water swimmer looks closely at a crocodile's cranium, they see thick scales covering their heads.

Researchers led by evolutionary biologist Michel Milinkovitch of the University of Geneva in Switzerland, who have assumed that the deep lines in the face and jaws of crocodiles marked the boundaries between thick scales, recently found out that the lines are actually simple physical cracks on the head.

"I was really surprised by these chaotic patterns of scales when I looked closely at the crocodile's head. There were all different sizes and different shapes. Comparing the left and the right, they were very different, and comparing different individuals, they were also very different."

Milinkovitch found that in late embryonic development, grooves began to appear in the thick skin covering the crocodile's head. And those cracks continue getting deeper and thicker, remaining for life.

Who knew?

Now we all do.

2014 Open Water Swimming Almanac

An Almanac for Open Water Swimming

An almanac is essentially a body of knowledge which is so complete that it enables people in different fields to make predictions about the future of their respective industries.

This, for example, was the purpose of the traditional farmers almanacs. It enabled farmers to determine as accurately as possible which crops to plant for the greatest harvests in a given year.

But the farmers almanac was just one example among many.
There are, of course, many different kinds of almanacs.

In fact, there is even one for open water swimming...
