Jellyfish have no brain, but they do have a rudimentary nervous system! A defining characteristic of the cuttlefish, the cuttlebone is a porous internal shell that helps control buoyancy, making it functionally similar to swim bladders in fish. Omega-3s help build cell membranes in the brain and also may have anti-inflammatory and antioxidant effects that could protect brain cells. 1. While sharks lack a swim bladder that many bony fish have, some species of shark, like the sand tiger . Clams are also animals that have no brains.

(b) Amphibians have two circulatory routes: one for oxygenation of the blood through the lungs and skin, and the other to take oxygen to the rest of the body. It is a large, reef-building coral that lives throughout the Caribbean Sea and adjacent waters. Although jellyfish do not have a brain, they have a very basic set of nerves or a nerve net that spreads radially through the jellyfish. Jellyfish do NOT have brains (or bones, teeth, blood…or even hearts). Fatty fish. (ii) The granular cell layer consists of small granular cells and also receives the Purkinje cell axons. 4. Not many fish have had the neurons in their brains counted, however, an adult zebrafish has been counted at ~10,000,000 neurons and a goldfish should be fairly similar. cells, signals are sent to our brain. . The term jellyfish generally refers to the umbrella-shaped gelatinous zooplanktons that belong to Scyphozoa (true jellyfish), Staurozoa (stalked jellyfish), Cubozoa (box jellyfish), and Hydrozoa of Phylum Cnidaria.
