The researchers found that wild cleaner fishes can remember being caught up to 11 months after the fact. The study, published in the Proceedings of the Royal Society B: Biological Sciences, is the first to show that cleaner fish are able to remember the location of their catch, even if they have not been seen for more than a year.

What animal has the shortest memory?
Bees had the worst memory, with a recall time of just 2.5 seconds. The bees earned a spot on the list of top 10 animals with the worst memory. The study, published in the Journal of Experimental Psychology: Learning, Memory and Cognition, was conducted by a team of researchers from the University of California, Berkeley, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.
What fish has the longest memory?
According to a new study, dolphins have the longest memories of their life.
The study also revealed that these dolphins are the most intelligent animals that have lived on the planet since humans evolved from a single-celled ancestor more than 200 million years ago AFP/Getty 42/100 Mysterious ‘X-Files’ sounds heard miles above the Earth ‘Alien sounds’ have been captured at the edge of space. he hisses and whistles were captured 22 times faster than the best human recordings, and were recorded by a group of international scientists, leading the way for scientists to understand the physics behind the sounds and see if they can make them heard by humans again, the Oxford University researchers said.The findings, published by the British Geological Survey (BGS), set a record for the fastest ever sound recorders to be made on planet Earth.
Do fish feel pain when caught on a hook?
Fish have many nociceptors in their mouths and getting hooked is very painful for them. In addition to this, they also have a very strong sense of smell, which is why they are able to detect the presence of other fish in the water. They are also very good swimmers and can swim for long periods of time without getting tired.
Does fishing traumatize fish?

What animal has 32 brains?
Leech has a bunch of brains. A leech’s internal structure is divided into 32 separate segments, each with its own brain. Leeches have a brain that is about the size of a human brain, but it is much smaller than the brain of an adult human.
The brain is made up of about 100 billion nerve cells, which are connected to each other and to the rest of the body through a network of blood vessels and nerves. Each nerve cell has about 10,000 synapses, or connections to other neurons. Leeches also have about 1,500 nerve endings in their bodies, each with a different function.
What animal is stupidest?
Sloths are the smartest animals around. They sleep on the tree branches, but never poop on the trees. They descend once a week to do their work on the ground and then go to sleep. The elephant is the largest land animal in the world, with a trunk that can weigh up to 1,000 pounds.
It is also one of the most intelligent animals on earth, able to use tools and communicate with other elephants and other animals. However, it is not a very social animal, preferring to stay in one place and stay out of trouble.
