Fishes use the same five major senses that all humans have: hearing, sight, smell, taste, and touch. But for fishes, all of these senses differ somewhat from our normal day-to-day experience.
Quite simply, living in a liquid environment is a very different thing than living in a gas (air) environment. Think about the difference between smell and taste. At some level tasting is like smelling wet things. How different are these senses when you are already wet or underwater? From an evolutionary or anatomical perspective, they do have fundamental, different origins and innervations, but because of their aquatic lifestyle these senses have more overlap in fishes when compared to humans. Given this similarity, one of the most striking differences is that fishes actually cover various parts of their bodies (ranging from their skin to specialized barbels, whiskers, or fin rays) with taste buds rather than just focusing on the tongue like we do. The whiskers of a catfish, like the one shown here, allow these fishes to taste the mud that they are digging around in. Would you want to drag your tongue around in the mud? We wouldn’t either.
Humans actually have more than five senses. For example, we have sensors for balance, temperature, and pain, but the five main senses dominate our daily lives and take up more relative sensory area in our brains. Fishes have two other major senses that are not found among the senses we experience: electroreception and mechanoreception (or distance touch). Electroreception is less common among fishes, but it is comparatively easy to grasp. This electro-sensitive system is much like a beach comber searching a sandy beach for valuable metals. Fishes use this system for a variety of reasons, but many fishes use this sense for hunting or gathering. A hammerhead shark or paddlefish will move the enlarged regions of their heads to search for small electrical signals in the water coming from animals respiring or moving. Specifically, fishes respiring underwater produce a small ionic charge that will stimulate electroreceptors, which allows a predator to find a sand dab or sea robin buried under the sand.
Mechanoreception is the sensory system that allows fishes to school, fishes to measure the surrounding current to hold their position in a moving stream, and fishes in the dark (e.g., deep-sea or caves) to find cave walls or rocky outcroppings. This is carried out by particular hair cells that are housed in a series of tubed scales along the side of a fish, found on the surface “pit organs” that cover the skin of some fishes, and distributed within bony canals in the head of a fish. These specialized hair cells or neuromasts are stimulated (bent/displaced) by the change in motion of water over the structures. This bending of the hairs in particular directions tells the fish that their schooling partners are changing direction or that a shark is quickly approaching, hence its common name of distance touch. If you are like us, you wish that you had these other wonderful vertebrate senses; but alas, they only work when you live underwater…
About the city:In João Pessoa, where the sun rises first in the American continent, everyone desires dawn to start the sooner the better and afternoon to go far beyond its limits. Here, our sea shore has an art master-piece status; a several kilometers far canvas painted to be surprised, lived, immersed end heart felt.
South bound shore is near town but far from its urbanity. A place where you forget yours problems listening to sea water which, by the way, are crystal clear, surrounded by colorful cliffs just beneath an “all-blue-making” sky. João Pessoa enhances the spirit.
At urban beaches, nature is surrounded by options. The sun invites for a bath. The sea urges for a dive. The sidewalk proposes a jog. Night invites a party, but before that, day must end in a stylish way. So when sunset comes, poetry wakes up to the sound of Maurice Ravel’s Bolero every day at Jacaré Beach. Meanwhile, horizon prepares itself for the next dawn.
João Pessoa is a place of open windows, so that the breeze between back yard and greenery jumps to the eyes. Here, nature goes beyond its habitat to be part of the urban scene and of each one’s life, or even better, part of life’s quality.
Breathe deep, you’re about to know a city that still holds a rain forest reservoir where green does not abridges itself to forest; it’s in plazas, at the city gantries , in the among nature. Here, beauty is in the eyes of those who look at the city from any point of view. João Pessoa is beautiful to live in.
