What is the dumbest animal?
Given that sponges and jellyfish are animals, and they don’t have as much as a single brain cell, the answer would seem to be no, but let’s just look at the the universe of animals with brains, however tiny. In this world, it is commonly said that the domesticated turkey is the dumbest animal on the planet.
Which animal is the most intelligent?
What are the smartest animals in the world and how do we know?

What animal has the best memory?
Marine mammals can remember their friends after 20 years apart, study says. Sorry, elephants: Dolphins have taken the top spot for best memory, at least for now.
Does Brain Size Matter in intelligence?
Researchers have been able to identify correlates of intelligence within the brain and its functioning. These include overall brain volume, grey matter volume, white matter volume, white matter integrity, cortical thickness and neural efficiency.
Do bigger dogs have bigger brains?
Summary: Larger dogs have better short-term memory and self-control than smaller breeds, according to new research. Bigger dogs, with larger brains, perform better on certain measures of intelligence than their smaller canine counterparts, according to a new study led by the University of Arizona.
Do dinosaurs have two brains?
This has led to the famous idea that dinosaurs like Stegosaurus had a “second brain” in the tail, which may have been responsible for controlling reflexes in the rear portion of the body.
Do fishes have blood?
Fish have a closed-loop circulatory system. The heart pumps the blood in a single loop throughout the body. In most fish, the heart consists of four parts, including two chambers and an entrance and exit. The bulbus arteriosus connects to the aorta, through which blood flows to the gills for oxygenation.

Are cats brains more similar to dogs or humans?
According to researchers at Tufts University School of Veterinary Medicine, the physical structure of the brains of humans and cats is very similar. The human brain and the cat brain both have cerebral cortices with similar lobes.
What fish has the smallest brain?
Fish hold records for the relative brain weights of vertebrates. Most vertebrate species have similar brain-to-body mass ratios. The deep sea bathypelagic bony-eared assfish, has the smallest ratio of all known vertebrates.
Do dolphins have a bigger brain than humans?
Brain structure. Elephant brains also show a complexity similar to dolphin brains, and are also more convoluted than that of humans, and with a cortex thicker than that of cetaceans.
What are Ossicones used for?
Male and female ossicones vary in structure and purpose. Males typically have thicker ossicones that become bald on top due to frequent necking. These ossicones also add weight to the giraffe’s head allowing them to deliver heavier, sometimes fatal, blows. The added weight is an evolutionary trait bred from necessity.
What is the smartest bird?
While parrots have the distinction of being able to mimic human speech, studies with the grey parrot have shown that some are able to associate words with their meanings and form simple sentences (see Alex). Parrots and the corvid family of crows, ravens, and jays are considered the most intelligent of birds.
Are elephants smarter than dolphins?
Elephants are believed to rank equal with dolphins in terms of problem-solving abilities, and many scientists tend to rank elephant intelligence at the same level as cetaceans; a 2011 article published by ABC Science states that, “elephants [are as] smart as chimps, [and] dolphins”.
Are orangutans clever?
Intelligence. Orangutans are among the most intelligent non-human primates. Experiments suggest they can figure out some invisible displacement problems with a representational strategy. In addition, Zoo Atlanta has a touch-screen computer where their two Sumatran orangutans play games.
Are sea lions smart?
Sea lions are particularly intelligent, can be trained to perform various tasks and display limited fear of humans if accustomed to them.
Why are owls wise?

Does lobster have blood?

Are sharks fish?
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays.
