Jervis Bay in New South Wales, Australia, where both settlements are located.

Octopolis and Octlantis are two non-human settlements occupied by gloomy octopuses (Octopus tetricus) in Jervis Bay, on the south coast of New South Wales. The first site, named "Octopolis" by biologists, was found in 2009. Octopolis consists of a bed of shells (mainly scallop shells) in an ellipse shape, 2–3 meters diameter on its longer axis, with a single piece of antropogenic detritus, believed to be scrap metal, within the site. Octopuses build dens by burrowing into the shell bed. The shells appear to provide a much better building material for the octopuses than the fine sediment around the site. Up to 14 octopuses have been seen at Octopolis at a single time. In 2016, a second settlement was found nearby, named "Octlantis," which includes no human-made objects and can house similar numbers of octopuses. [2] Both sites are within Booderee National Park. Some media accounts have described these sites as octopus "cities," but researchers who have worked on the sites view this as a misleading analogy. [3]

An octopus is a soft-bodied, eight-limbed mollusc of the order Octopoda. The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates.

<span class="mw-page-title-main">Cephalopod</span> Class of mollusks

A cephalopod is any member of the molluscan class Cephalopoda such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology.

The Lapita culture is the name given to a Neolithic Austronesian people and their distinct material culture, who settled Island Melanesia via a seaborne migration at around 1600 to 500 BCE. They are believed to have originated from the northern Philippines, either directly, via the Mariana Islands, or both. They were notable for their distinctive geometric designs on dentate-stamped pottery, which closely resemble the pottery recovered from the Nagsabaran archaeological site in northern Luzon. The Lapita intermarried with the Papuan populations to various degrees, and are the direct ancestors of the Austronesian peoples of Polynesia, eastern Micronesia, and Island Melanesia.

Monk seals are earless seals of the tribe Monachini. They are the only earless seals found in tropical climates. The two genera of monk seals, Monachus and Neomonachus, comprise three species: the Mediterranean monk seal, Monachus monachus; the Hawaiian monk seal, Neomonachus schauinslandi; and the Caribbean monk seal, Neomonachus tropicalis, which became extinct in the 20th century. The two surviving species are now rare and in imminent danger of extinction. All three monk seal species were classified in genus Monachus until 2014, when the Caribbean and Hawaiian species were placed into a new genus, Neomonachus.

The Caribbean reef squid, commonly called the reef squid, is a species of small, torpedo-shaped squid with undulating fins that extend nearly the entire length of the body, approximately 20 cm in length. They are most commonly found in the Caribbean Sea in small schools. As part of the Cephalopod class of Molluscs, these organisms exhibit specific characteristics to help them in their environment, such as tentacles for movement and feeding and color pigments that reflect their behavioral conditions.

The giant Pacific octopus, also known as the North Pacific giant octopus, is a large marine cephalopod belonging to the genus Enteroctopus. Its spatial distribution includes the coastal North Pacific, along Mexico, The United States, Canada, Russia, Eastern China, Japan, and the Korean Peninsula. It can be found from the intertidal zone down to 2,000 m (6,600 ft), and is best adapted to cold, oxygen-rich water. It is arguably the largest octopus species.

<span class="mw-page-title-main">Shark agonistic display</span> Animal behavior

Agonism is a broad term which encompasses many behaviours that result from, or are triggered by biological conflict between competing organisms. Approximately 23 shark species are capable of producing such displays when threatened by intraspecific or interspecific competitors, as an evolutionary strategy to avoid unnecessary combat. The behavioural, postural, social and kinetic elements which comprise this complex, ritualized display can be easily distinguished from normal, or non-display behaviour, considered typical of that species' life history. The display itself confers pertinent information to the foe regarding the displayer's physical fitness, body size, inborn biological weaponry, confidence and determination to fight. This behaviour is advantageous because it is much less biologically taxing for an individual to display its intention to fight than the injuries it would sustain during conflict, which is why agonistic displays have been reinforced through evolutionary time, as an adaptation to personal fitness. Agonistic displays are essential to the social dynamics of many biological taxa, extending far beyond sharks.

"Precambrian rabbits" or "fossil rabbits in the Precambrian" are reported to have been among responses given by the biologist J. B. S. Haldane when asked what evidence could destroy his confidence in the theory of evolution and the field of study. The answers became popular imagery in debates about evolution and the scientific field of evolutionary biology in the 1990s. Many of Haldane's statements about his scientific research were popularized in his lifetime.

<i>Octopus tetricus</i> Species of mollusc

Australian philosophy refers to the philosophical tradition of the people of Australia and of its citizens abroad. Academic philosophy has been mostly pursued in universities. It has been broadly in the tradition of Anglo-American analytic philosophy, but has also had representatives of a diverse range of other schools, such as idealism, Catholic neo-scholasticism, Marxism, and continental, feminist and Asian philosophy.
