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.

Caddisfly/ Stenopsyche griseipennis
Body length: 1.6 cm.
Caddisflies are holometabolous insects closely related to Lepidoptera. The nymphs of caddisflies are aquatic, living in the benthic zone of streams and other water bodies. Many of the related species build a net to catch food, such as algae, aquatic invertebrates and zooplankton from the flowing stream.
The central nervous system consists of the brain, subesophageal ganglion, 3 thoracic ganglia and 5 abdominal ganglia.
