Freshwater





Insects are almost completely lacking in the marine environment. I recall something about saltwater having a very bad effect on their lungless respiratory system ( although this does not affect spiders. ) Insects are quite common in freshwater environments though, both as larvae and adults. A little digging can turn up myriad types, but be careful, some of them can bite very painfully.

PARALLELS ARE OFTEN DRAWN BETWEEN DIVING AND FLYING. Both take place in an environment where the ambient pressure is different than the earth's surface - where we spend most of our time breathing - and both require formal training to qualify as a participant. Yet, on one point the two activities diverge completely. In flying, the highlight of a pilot's life is his or her first opportunity to solo - to operate the aircraft alone. In fact, after earning a private pilot's license, aviators commonly fly with no one other than God as their copilot.

Not so in diving; the admonition to "never dive alone" is considered the hallmark of safe diving.

To most divers, entering the water without a buddy is tantamount to a pilot taking off without doing a preflight check of the airplane. But to assume that buddy diving is an absolute universal practice would be a mistake. Lots of divers dive solo. Some do it intentionally, but most end up sans buddy completely by accident.
