“…More broadly, sociality is widespread in coleoids. In decapods, it manifests along a continuum from lifelong gregariousness in squid to episodic shoaling in cuttlefish (Drerup and Cooke, 2021). While octopi have instead often been portrayed as quintessentially solitary, this is not the case for all species.…”

Of all species on Earth, only one – Homo sapiens – has developed a technological civilization. As a consequence, estimates of the number of similar civilizations beyond Earth often treat the emergence of human-like intelligence or ‘sophonce’ as an evolutionary unicum: a contingent event unlikely to repeat itself even in biospheres harbouring complex brains, tool use, socially transmitted behaviours and high general intelligence. Here, attention is drawn to the unexpected recency and temporal clustering of these evolutionary preconditions to sophonce, which are shown to be confined to the last ≤102 million years. I argue that this pattern can be explained by the exponential biotic diversification dynamics suggested by the fossil record, which translated into a nonlinearly expanding range of cognitive and behavioural outcomes over the course of Earth's history. As a result, the probability of sophonce arising out of a buildup of its enabling preconditions has been escalating throughout the Phanerozoic. The implications for the Silurian hypothesis and the search for extraterrestrial intelligence (SETI) are discussed. I conclude that the transition from animal-grade multicellularity to sophonce is likely not a rate-limiting step in the evolution of extraterrestrial technological intelligences, and that while H. sapiens is probably the first sophont to evolve on Earth, on macroevolutionary grounds it is unlikely to be the last.

“…This behavior is an advantage of social groupings, as it saves time and energy by preventing trial-and-error learning (Coussi-Korbel & Fragaszy, 1995). The opportunity for social learning arises during spawning, which indicates that newborns also exhibit gregariousness (Drerup & Cooke, 2021;Hanlon & Messenger, 2018b). Further, juveniles have been found constituting shoals during migration (Drerup & Cooke, 2021), suggesting that cuttlefish developed a general type of social cognition, which can be useful in both social and non-social environments (Varela et al, 2020).…”

The ocean is undergoing deoxygenation and the spread of hypoxic areas. Ocean deoxygenation and standing levels of hypoxia are shrinking fundamental niches, particularly in coastal areas, yet documented repercussions on species development and behavior are limited. Here, we tackled the impacts of deoxygenation (7 mg O2 L-1), mild hypoxia (nocturnal 5 mg O2 L-1), and severe hypoxia (2 mg O2 L-1) on cuttlefish (Sepia officinalis) development (hatching success, development time, mantle length) and behavior, i.e., ability to learn (associative- and socially), to camouflage, and to explore its surroundings spatially. We found that hypoxia yielded lower survival rates, smaller body sizes and inhibited predatory (increased latency to attack the prey) and anti-predator (camouflage) behaviors. Acute and chronic exposure to low oxygen produced similar effects on cognition (inability to socially learn, increased open-field activity levels, no changes in thigmotaxis). It is thus expected that, although cuttlefish can withstand oxygen limitation to a certain degree, expanding hypoxic zones will diminish current habitat suitability.

“…Cuttlefish may therefore have a partially social life and are known to aggregate, sometimes in large numbers, for breeding on a seasonal basis (e.g. European common cuttlefish, Sepia officinalis ; Broadclub cuttlefish, Sepia latimanus ; Australian giant cuttlefish, Sepia apama ) (Norman et al, 1999, Hanlon et al, 2005, Yasumuro et al, 2015, Drerup and Cooke, 2021).…”

Cuttlefishes, like their octopus cousins, are masters of camouflage by control of body pattern and skin texture to blend in with their surroundings for prey ambush and threat avoidance. Aside from significant progress on the cuttlefish visual perception and communication, a growing number of studies have focused on their behavioural neurobiology and the remarkably rapid and apparently cognitively complex reactions to novel challenges such as spatial learning to solve maze tasks and vertebrate-like cognitive capabilities (e.g. object recognition, number sense and episodic-like memory). Despite intense interest of cuttlefish, much of our knowledge of its neuroanatomy and links to behaviour and ecology comes from one temperate species, the European common cuttlefish, Sepia officinalis. Here we present the first detailed comparison of neuroanatomical features between the tropical cuttlefish and squid and describe differences in basic brain and wiring anatomy using MRI-based techniques and conventional histology. Furthermore, comparisons amongst nocturnal and diurnal cuttlefish species suggest that the characteristic neuroanatomical features infer interspecific variation in visual capabilities, the importance of vision relative to the less utilised chemosensory system and clear links with life modes (e.g. diurnal vs nocturnal), ecological factors (e.g. living depth and ambient light condition) as well as to an extent, phylogeny. These findings link brain heterogeneity to ecological niches and lifestyle, feeding hypotheses around evolutionary history and provide a timely, new technology update to older literature.
