Ronald R. Hoy, Cornell University professor of neurobiology and behavior, considers the spider “one of the smartest of all invertebrates.” But while its behavior is comparable to that of many vertebrates, its anatomy is not:
“Dr. Hoy and his colleagues wanted to study jumping spiders because they are very different from most of their kind. They do not wait in a sticky web for lunch to fall into a trap.
They search out prey, stalk it and pounce. “They’ve essentially become cats,” Dr. Hoy said.
And they do all this with a brain the size of a poppy seed and a visual system that is completely different from that of a mammal: two big eyes dedicated to high-resolution vision and six smaller eyes that pick up motion. – James Gorman, “Unexpected Complexity in a Spider’s Tiny Brain” at New York Times (November 3, 2014) … “
Another new study provides evidence that jumping spiders can plan their attacks. Denyse O’Leary, “In what ways are spiders intelligent?” at Mind Matters News
