The Box Jellyfish Packs A Powerful Punch

In a recent article, the venomous box jellyfish was mentioned.

"…the box jellyfish, normally found in the Indo-Pacific, had migrated to the Florida Strait. Almost transparent, with 5,000 toxin-firing barbs on each 10-foot-long tentacle, the box jellyfish is particularly venomous…"

Note entirely true according to jellyfish expert Dr. Angel Yanagihara.

"The box jellyfish or cubozoans have been identified in the Florida Straits and Carribean for over 100 years. The numbers of box jellies, appear to be increasing perhaps in part due to the loss of their natural predators, turtles, sun fish, pelagic fish, thus stacking the deck in favor of increasing jelly populations. Also, the microscopic stinging cells are present at up to 5,000 per centimeter of tentacle length or for a 18-inch tentacle 225,000 per tentacle. Far more than what was reported."

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...
