A traditionally common image is the scala naturae, the ladder of nature on which animals of different species occupy successively higher rungs, with humans typically at the top. [ 165 ] [ 166 ] However, there is some disagreement with the use of such a hierarchy, with some critics saying it may be necessary to understand specific cognitive ...
Not all animals have neurons; Trichoplax and sponges lack nerve cells altogether. Neurons may be packed to form structures such as the brain of vertebrates or the neural ganglions of insects . The number of neurons and their relative abundance in different parts of the brain is a determinant of neural function and, consequently, of behavior.
The corvids (ravens, crows, jays, magpies, etc.) and psittacines (parrots, macaws, and cockatoos) are often considered the most intelligent birds, and are among the most intelligent animals in general. Pigeons, finches, domestic fowl, and birds of prey have also been common subjects of intelligence studies.
Poodles, Rottweilers, Doberman Pinchers, Papillons, Australian Cattle dogs, and Shetland Sheepdogs round out the top ten on researcher Stanley Coren's list of smartest breeds. But it's important ...
Though these criteria are difficult to measure in nonhuman animals, cephalopods are the most intelligent invertebrates. The study of cephalopod intelligence also has an important comparative aspect in the broader understanding of animal cognition because it relies on a nervous system fundamentally different from that of vertebrates.

The first toy breed to crack the top 10, papillons aren't your average lap dogs. The 5-pound wonders often take home top prizes at competitive agility trials, according to the American Kennel Club .
AKC doesn’t rank dogs from most to least smart; however, the list can still give you an idea of which dog breeds tend to be the most intelligent and few characteristics that make them so ...
Pigs are among the most intelligent mammals on the planet; as such, they display a wide range of complex behaviors, like being able to play video games, understanding human instructions and even a pig species has been observed using tools.
