Below is the bruising which can result from failure to keep sufficient air in your dry suit on the way down on a dive, in this case down to 4 atmospheres, or 4 times surface pressure = 60lbs/sq.in.
By the time you reach 60 ft., the ambient water pressure makes you feel as if your entire body is caught in a giant vice grip.
It was pure stupidity on my part of course, for having failed to check to make sure my dry suit hose was connected to deliver air pressure into the suit before the dive.
A helpful dive buddy assisted me in reconnecting it at 60 ft. and restoring pressure, but this is the result of not checking your hoses before a dive.
–Remember: it’s always better to learn from the mistakes of others, rather than your own!

“That deadly beak may be a surprise to many people and has long posed a puzzle for scientists. They wonder how a creature without any bones can operate it without hurting itself.
The beak, made of hard chitin and other materials, changes density gradually from the hard tip to a softer, more flexible base where it attaches to the muscle around the squid’s mouth, the researchers found.
That means the tough beak can chomp away at fish for dinner, but the hard material doesn’t press or rub directly against the squid’s softer tissues
The razor-sharp beaks that giant squids use to attack whales – and maybe even Captain Nemo’s submarine – might one day lead to improved artificial limbs for people. “

BOSTON – Call them Pavlov’s fish: Scientists are testing a plan to train fish to catch themselves by swimming into a net when they hear a tone that signals feeding time.
If it works, the system could eventually allow black sea bass to be released into the open ocean, where they would grow to market size, then swim into an underwater cage to be harvested when they hear the signal.

As long as they promise to stop making Grade ‘D’ movies about it, I’ll be happy…….
