| This conducts sound better than other bones, thus aiding biosonar. |
| Such noise can disrupt cetacean behavior such as their use of biosonar for orientation and communication. |
| Porpoises have the ability to produce biosonar and it is their primary sensory system. |
| Marine mammals that make use of biosonar for orientation and communication are not only hindered by the extra noise, but may race to the surface in panic. |
| This is filled with air sacs and fat that aid in buoyancy and biosonar. |
