If you're lucky enough to be jetting off to the Bahamas, then Nassau should be the diving destination for you. Whilst there are hundreds of beautiful locations for Bahamas-based diving, there's something special about 'Paradise Island'.
We all know, or should know, that if we suspect a diver is suffering from decompression sickness, that the immediate first aid response is to provide the diver with pure oxygen.
Some land animals like rats and shrews use their whiskers to explore, forage and move around. For the first time, a team of researchers, led by Robyn Grant of Manchester Metropolitan University, were able to show that pinnipeds too use their whiskers in a similar fashion.
The study, published in the Journal of Comparative Physiology A sought to measure and compare whisker movements and control amongst three pinniped species—California sea lions, harbor seals and Pacific walruses.

This scenario may one day become reality. And to be efficient, such robots would need to be maneuverable and stealthy, and be able to closely mimic the movements of the marine creatures.
Scientists like Keith W. Moored are working on the next generation of underwater robots by studying the movements of dolphins and whales. "We're studying how these animals are designed and what's beneficial about that design in terms of their swimming performance, or the fluid mechanics of how they swim."
You need some kind of hand protection on most dives, and there is a massive range of gloves out there that cover all eventualities.
The diving community understands that oxygen administration is a first aid treatment priority for divers with suspected decompression illness. The goal is to deliver oxygen at the highest possible concentration, being mindful of oxygen supply limits.
