Remember the last time you were itching to tell your friend something silly that you saw while walking around town? Remember how easy it was to do that? When you think about it, it is extremely easy for humans to communicate with one another! We have telephones to text or call our friends, we have computers that we can use to Skype, or we can simply meet face to face and have an old-fashioned conversation. It\u2019s that simple!<\/p>\n

However, is the same thing true for other creatures, like fish? Is it just as easy for them to communicate with one another? Perhaps more importantly, can they communicate with each other at all?<\/p>\n

Well, just like us\u00a0humans, fish can communicate with one another, and they do so using sound, smell, coloration, motion, bioluminescence and electric impulses.<\/p>\n

Sound<\/h2>\n

As you know, sound travels slower than light, but sound can travel further under the right conditions. Light travels only a short distance before it is scattered or absorbed underwater. In deeper areas, it is even more difficult to see the light, further limiting vision for many marine animals. On the other hand, sound travels much greater distances underwater. Strong echoes emitted by different animals are almost always present underwater, as very little noise is lost.<\/p>\n

\"tropical<\/p>\n

Do fish ever get confused by the number of sounds being emitted by different individuals underwater? Fun fact\u2026 they don\u2019t!<\/p>\n<\/div>\n

Three types of sounds are generally used by fish to communicate with one another\u2014purr, crock and pop. Most of these sounds are inaudible to humans and are used during spawning, breeding and fighting. Sound is also used to navigate from one place to another and to identify the presence of predators and prey.<\/p>\n

<\/div>\n

Oyster toadfish produce courtship calls to lure potential mates after building a suitable nest.<\/p>\n

\"perfectly<\/p>\n

\n<\/div>\n

Damselfish on the other hand, use sound to protect their territories from predators. Whenever these fish sense an intruder, they spontaneously produce sounds.<\/p>\n

How is this sound produced?<\/h3>\n

In many fish, the swim bladder produces sound. The sonic muscle, which is attached to the swim bladder, contracts and relaxes sequentially. This makes the swim bladder vibrate, which in turn produces sound. Similarly, sound is also produced when hard parts of the body, such as teeth and bones, strike each other.<\/p>\n

Smell<\/h2>\n

There is still a lot we don\u2019t know about how fish communicate through\u00a0scent. However,\u00a0a recent study\u00a0reports that certain cichlids use urine as a medium to send chemical signals to rivals during aggressive displays. These fish urinate to get their scented message across!<\/p>\n

Color<\/h2>\n

This is definitely the most developed form of communication in fish. Many fish are capable of brightening or darkening their skin, while some can glow or even change their colors to mimic other fish. Bright colors are also used by fish who aren\u2019t excellent swimmers to tell other fish to stay away. These fish use color as a warning sign to predators.<\/p>\n

For instance, groupers are known to alter their colors to communicate that that they\u2019re willing to spawn.<\/p>\n

\"Red<\/div>\n

Motion<\/h2>\n

Not all fish can produce sound to communicate, so under these circumstances, body language or movement is used instead. For instance, fish can create sound by\u00a0vibrating their swim bladders.<\/p>\n

Bioluminescence<\/h2>\n

Some fish that live in deep waters generate light from their organs through a chemical reaction. As it is difficult to see in the deep parts of the world\u2019s oceans, bioluminescence<\/a> helps in fish recognition and communication with other creatures who are similarly hard to see!<\/p>\n

Many fish use organs known as photophores to emit light that appears as luminous spots on their bodies. For instance, photophores are present along the belly of lantern fish. Some fish have photophores on the sides of their body, which can be used to help identify different individuals and for interspecific communication.<\/p>\n

Electrical Impulses<\/h2>\n

Finally, some fish have electrical organs that enable them to transmit electrical impulses. These impulses are usually directed at predators, warning them to stay away.<\/p>\n","protected":false},"excerpt":{"rendered":"
