Australian Submarine Rescue Vehicle Remora (ASRV Remora) was a submarine rescue vehicle used by the Royal Australian Navy (RAN) between 1995 and 2006. The name comes from the remora , a small fish that can attach itself to larger marine life, and has the backronym "Really Excellent Method of Rescuing Aussies ".
Underwater breathing apparatus can be classified as open circuit, semi-closed circuit, (including gas extenders) or closed circuit (including reclaim systems), based on whether any of the exhaled gas is recycled, and as self-contained or remotely supplied (usually surface-supplied, but also possibly from a lock-out submersible or an underwater habitat), depending on where the source of the ...
Medical anaesthesia breathing systems – to supply controlled concentrations of anaesthetic gases to patients without contaminating the air that the staff breathe, and to conserve anaesthetic gas. Life-support systems of submarines, underwater habitats, and saturation diving systems use a scrubber system working on the same principles as a ...
The system maximizes the use of low-pressure bank gas and minimizes the use of high-pressure bank gas. [2] Another method for scavenging expensive low pressure gases is to pump it with a gas booster pump such as a Haskel pump, or to add it to the intake air of a suitable compressor at atmospheric pressure in a mixer known as a blending stick.

The semi-closed rebreather systems developed by Drägerwerk in the early 20th century as a scuba gas supply for Standard diving dress, using oxygen or nitrox, and the US Navy Mark V Heliox helmet developed in the 1930s for deep diving, circulated the breathing gas through the helmet and scrubber by using an injector system where the added gas ...

The sucking disc begins to show when the young fish are about 1 cm (0.4 in) long. When the remora reaches about 3 cm (1.2 in), the disc is fully formed and the remora can then attach to other animals. The remora's lower jaw projects beyond the upper, and the animal lacks a swim bladder. [9] Some remoras associate with specific host species.
