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.

Barbados chocolate millipede/ Rhinocricus sp.
Body length: 9 cm.
These millipedes are distributed in Cuba and are coveted by fans.
The central nervous system consists of the brain, subesophageal ganglion and a number of abdominal ganglia in line. However, the abdominal ganglia other than the terminal abdominal ganglion are not apparent in this photograph due to the connective tissue wrapping up the nerve cord.
