 Our relationship to the octopus dates back to prehistory, when the eight-armed animal was depicted on vases and found in stone carvings from ancient Greece. Now we appreciate them for their abilities as escape artists, with sophisticated camouflage systems and ink jets—as well as their roles in tasty dishes from many cuisines. Octopuses are also among the most intelligent invertebrates in the world, with mental capacity comparable to that of a dog. In this heavily illustrated book, Richard Schweid details this animal’s remarkable natural history and its multifaceted relationship with humans.

 
Schweid describes the octopus’s intelligence, defense mechanisms, and short lifespan. He shows how some people have considered octopuses as nothing more than a meal and examines their role in the modern global fish and seafood industry. Other cultures, he reveals, see them as erotic totems or symbols of the darkest evils, and he discusses the difficulties people face when trying to keep them as pets—they are able to use their problem-solving skills, mobility, and boneless body to escape seemingly secure tanks. A fascinating glimpse into the extraordinary world of these popular creatures, Octopus will immerse readers in its amazing undersea world.

Complex behaviours and learning and memory. The octopus is an ideal animal for such a study, as it is a unique invertebrate mollusc with learning abilities similar to those of vertebrates.22 Octopus behaviour has a level of sophistication unequalled in any other invertebrate. Researchers hope that by identifying and studying the mechanisms they have evolved for dealing with their world, clues may be uncovered that will help us understand our own evolution and development as cognitive beings.

Dried. These days, if not eaten fresh, it is frozen and eaten later. To appreciate the Galician appetite for octopus, the best time to visit is during the octopus festival in the town of O Carballiño. A dozen neighbours got together in 1964 for the first of the fiestas honouring the octopus, and in 50 years it has grown to be one of Galicia’s largest and most important festivals. By 2010 the festival had gained an international reputation, and nearly 45,000 kg (100,000 lb) of octopus was consumed.

Relieving fatigue that July 2 unofficially has been named Day of the Octopus … ‘Octopus can be caught throughout most of the year off Akashi, but it tastes best from July to the Bon season in August’, said Yosuke Maeda, an employee of the Akashiura fisheries cooperatives. ‘In summer, shrimps and crabs, the favourite foods of octopuses, are abundant. So octopuses caught around this time are most delicious.’ The current is strong in this area, which makes octopuses chewy and tastier … The city’s.

Less likely to bite, so it’s important to keep a captive octopus well fed. Adults are generally fed frozen seafood, and a lot of it. That’s okay if a person lives near the coast, but inlanders can wind up paying quite a bit for their octopus’s diet. At any rate, uniformity in feeding hours is recommended. In some cases feeding time will be the only time of the day when an octopus will allow itself to be seen. Creating the correct kind of complex environment with plenty of places to hide and the.
