Octopuses can maintain a constant oxygen uptake even when oxygen concentrations in the water decrease to around 3.5 kPa (0.51 psi) [22] or 31.6% saturation (standard deviation 8.3%). [17] If oxygen saturation in sea water drops to about 1–10% it can be fatal for Octopus vulgaris depending on the weight of the animal and the water temperature ...
The octopuses seen in the videos threw silt, shells, and algae at other nearby octopuses. To do so, they gathered up the debris underneath their bodies using their arms. They then used their ...

For example, frogs use vocal sacs and an air-recycling system to make sound, while pipid frogs use laryngeal muscles to produce an implosion of air and create clicking noise. [7] Aquatic mammals such as seals and otters can produce sound using the larynx.
