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.

Giant water bug/ Lethocerus deyrollei
Body length: 4.8-6.5 cm.
Giant water bugs like freshwater streams and ponds. They feed on aquatic arthropods, snails, small fish, salamanders, frogs and toads.
Posterior to the brain, the subesophageal ganglion and the prothoracic (first thoracic) ganglion are merged together, and the remaining 2 thoracic ganglia and abdominal ganglia merge into a single ganglion. Optic lobes are extended anterolaterally to the brain.
