Invertebrate Brain Gallery

Many invertebrate animals have evolved a rich variety of brains (head ganglia). Unusually large brains of squids and octopuses and small but sophisticated brains of arthropods, especially those of insects, are among the most fascinating brains created on earth by natural selection. Here, photographs of invertebrates of 6 phyla, 35 orders and 47 species and those of their central nervous systems are presented, with brief explanations of their characteristics. Enjoy seeing the pictures and consider evolution of brains in invertebrates. These images can be only used for research and education freely. Providers (Dr. Makoto Mizunami) have copyright for images and documents.

Stonefly/ Kamimuria tibialis
Body length: 20-25 mm (male), 25-28 mm (female).
Stoneflies are hemimetabolous insects found throughout Japan and on the Korean Peninsula. They are believed to be one of the most primitive groups of insects. The nymphs are aquatic, living in the benthic zone and shallow waters of streams, whereas the adults are terrestrial. Both nymphs and adults have long paired cerci arising from the sides of the posterior ends of their abdomen. In Nagano (Japan), there is a custom of eating zazamushi, nymphs of stoneflies and caddisflies.
The central nervous system consists of the brain, subesophageal ganglion, 3 thoracic ganglia and 6 abdominal ganglia linked in line with a pair of connectives, typical of insect central nervous systems.
