A new study by Ziegler and Sargony (2021) has demonstrated how non-invasive methods can be used to record and catalogue new species of megafauna. Traditional methods including collecting specimens to handle physically which, aside from killing the specimen, can also damage the structures of the organism - impairing proper scientific understanding. While non-destructive imaging techniques have proven effective in describing novel species of small organisms this is the first time it has be utilised for a deep-sea megafauna, the cirrate octopus - Grimpoteuthis imperator.
In a recent forum by Youngentob et al. (2021) pose this fascinating question, given that endotherms commonly reduce their voluntary food intake in warm temperatures - could reduced food intake be an overlooked driver of climate change casualties?
A recent study in the journal of Marine Biology has tested a different method of investigating social behaviour in octopuses. Traditionally octopuses have been seen as asocial creatures that ignore others of their species (conspecifics) but recent discoveries of aggregations or groups of wild octopuses such as: algae octopuses (Abdopus aculeatus), Graneledone octopuses, Muusoctopus octopuses, Caribbean Reef Octopuses (Octopus briareus), Atlantic pygmy octopuses (Octopus joubini), Octopus laqueus, Common Sydney octopuses (Octopus tetricus) and Vulcanoctopus hydrothermalis.
