Camouflage and Exploratory Avoidance of Newborn Cuttlefish under Warming and Acidification
Biology, 2022 Ocean warming and acidification have been shown to elicit deleterious effects on cephalopod mollusks, especially during early ontogeny, albeit effects on behavior remain largely unexplored.

Influence of Temperature, Hypercapnia, and Development on the Relative Expression of Different Hemocyanin Isoforms in the Common Cuttlefish Sepia officinalis [PDF]
, 2012 The cuttlefish Sepia officinalis expresses several hemocyanin isoforms with potentially different pH optima, indicating their reliance on efficient pH regulation in the blood.

Sensorial Hierarchy in Octopus vulgaris’s Food Choice: Chemical vs. Visual
Animals, 2020 Octopus vulgaris possesses highly sophisticated sense organs, processed by the nervous system to generate appropriate behaviours such as finding food, avoiding predators, identifying conspecifics, and locating suitable habitat.

Acoustically evoked potentials in two cephalopods inferred using the auditory brainstem response (ABR) approach [PDF]
, 2009 It is still a matter of debate whether cephalopods can detect sound frequencies above 400 Hz. So far there is no proof for the detection of underwater sound above 400 Hz via a physiological approach.

Female impersonation as an alternative reproductive strategy in giant cuttlefish [PDF]
, 1999 Out of all the animals, cephalopods possess an unrivalled ability to change their shape and body patterns. Our observations of giant cuttlefish (Sepia apama) suggest this ability has allowed them to evolve alternative mating strategies in which males can

Dynamic mimicry in an Indo-Malayan octopus [PDF]
, 2001 During research dives in Indonesia (Sulawesi and Bali), we filmed a distinctive long-armed octopus, which is new to science. Diving over 24 h periods revealed that the 'mimic octopus' emerges during daylight hours to forage on sand substrates in full ...

Cuttlefish color change as an emerging proxy for ecotoxicology
Frontiers in Physiology, 2023 Lately, behavioral ecotoxicology has flourished because of increasing standardization of analyses of endpoints like movement. However, research tends to focus on a few model species, which limits possibilities of extrapolating and predicting ...
