[10] Octopus eyes, too, look and work much like those of vertebrates; but there, Baer remarks, the similarities end. Cephalopods are "immensely foreign", with "a distributed sense of self" and a "lived reality" quite unlike human consciousness, a feature that, he notes, Godfrey-Smith calls "the most difficult aspect of octopus experience to ...
An octopus traveling with shells collected for protection. Despite evolving independently from humans for over 600 million years, octopuses demonstrate problem-solving abilities, adaptive learning, and likely sentience. [92] Cephalopods are capable of complex tasks, thus earning them the reputation of being among the smartest of invertebrates.
A veined octopus eating a crab.. Unlike most other molluscs, all cephalopods are active predators (with the possible exceptions of the bigfin squid and vampire squid).Their need to locate and capture their prey has likely been the driving evolutionary force behind the development of their intelligence.
Meanwhile, Washington and California are among several states where lawmakers this year have considered bans on octopus farming, a species for which scientists have found strong evidence of sentience.
Sentience: the ability to be aware (feel, perceive, or be conscious) of one's surroundings or to have subjective experiences. Sentience is a minimalistic way of defining consciousness, which is otherwise commonly used to collectively describe sentience plus other characteristics of the mind.
More than 20 years later, various projects have created parts of the octopus such as a soft robotic arm that has many of the features of a tentacle, and today there are a number of projects ...
Legs reduce friction, and with legs, bilateral symmetry makes coordination easier. Sentient organisms will, Villazon argues, likely use tools, in which case they need hands and at least two other limbs to stand on. In short, a generally humanoid shape is likely, though octopus- or starfish-like bodies are also possible. [12]
Using octopus genomics was “an innovative and exciting way” to address an important question about historical climate change, said Douglas Crawford, a professor of marine biology and ecology ...
