Journal Article: Southern Sand Octopus
In September 2015, we reported on the Southern Sand Octopus’s remarkable ability to burrow into the sand using jets of water to fluidise the sediment – essentially creating quicksand – that it can then dive into. This behaviour has never been reported before in octopuses, but may be more common than we think.
The octopus is also unique in its ability to form a sub-surface mucous-lined burrow under the sand, where it resides during the day.
