Liberdade class blended wing bodies are autonomous underwater gliders developed by the US Navy Office of Naval Research which use a blended wing body hullform to achieve hydrodynamic efficiency. It is an experimental class whose models were originally intended to track quiet diesel electric submarines in littoral waters , moving at 1–3 knots ...
Aquatic insects or water insects live some portion of their life cycle in the water. They feed in the same ways as other insects.Some diving insects, such as predatory diving beetles, can hunt for food underwater where land-living insects cannot compete.
The evolution of flippers in penguins was at the expense of their flying capabilities, in spite of evolving from an auk-like ancestor that could 'fly' underwater as well in the air. Form constrains function, and the wings of diving flying species, such as the murre or cormorant have not developed into flippers. The flippers of penguins became ...

Diving equipment, or underwater diving equipment, is equipment used by underwater divers to make diving activities possible, easier, safer and/or more comfortable. This may be equipment primarily intended for this purpose, or equipment intended for other purposes which is found to be suitable for diving use.
Initially released as a digital title in August 2016, a retail version for consoles was released in January 2017. Following the journey of a diver exploring the ocean and restoring life using sonar calls, the gameplay allows the player to freely navigate underwater environments ranging from open water and natural caverns to ancient ruins.
The white-throated dipper and American dipper are also known in Britain and America, respectively, as the water ouzel (sometimes spelt "ousel") – ouzel originally meant the only distantly related but superficially similar Eurasian blackbird (Old English osle). Ouzel also survives as the name of a relative of the blackbird, the ring ouzel. [6]
They are strong fliers; their broad, blunt-tipped wings require faster wing-beats than those of many ducks and they take off with some difficulty. Northern species tend to be migratory ; southern species do not migrate though the hardhead travels long distances on an irregular basis in response to rainfall.
