JELLYFISH Jellyfish have been around for more than 500million years but until now they've been thought of as simple creatures with limited learning abilities. The prevailing scientific opinion is that more advanced nervous systems equate with more advanced learning potential in animals. Jellyfish and their relatives, collectively known as cnidarians, are considered to be the earliest living animals to develop nervous systems - and to have fairly simple ones with no centralized brain. Neurobiologist Professor Anders Garm has been researching box jellyfish, a group commonly known for being among the world's most poisonous creatures, for more than a decade. The fingernail-sized species live in Caribbean mangrove swamps where they use their impressive visual system, including 24 eyes, to hunt for tiny copepods among the roots. Prof Garm, of the University of Copenhagen in Denmark, said: "It was once presumed that jellyfish can only manage the simplest forms of learning, including habituation – the ability to get used to a certain stimulation, such as a constant sound or constant touch. "Now, we see that jellyfish have a much more refined ability to learn, and that they can actually learn from their mistakes. And in doing so, modify their behavior." He said one of the most advanced attributes of a nervous system is the){kind=link}
