Still, the sponge does not have a nervous system, but it can react to the environment by changing the size of the tube of the filter feeding system by an action called "expansion / contraction reaction". It's basically similar to what we do when we sneeze. 12th. 2014г. A sponge is a strong animal with a dense skeleton that adapts well to its environment. They can adapt to the areas and surfaces in which they grow, as they can live almost everywhere. Certain sponge species adapt to freshwater environments. Their skeletal type allows them to live in either hard or soft deposits. It is the normal sponge cells that detect these stimuli, not the special sensory cells, and the sponge response is probably regulated by simple mechanical coordination between normal somatic cells.
Why does the sponge never sleep?
As Hirsch and Kelly said, the sponge does not sleep because it lacks the central nervous system and brain. Sponges are still classified as animals rather than plants, but they do not have a brain or central nervous system.
Does the sponge have a nervous system?
The sponge has no nervous system. Animals need to have a large central nervous system to need sleep. Animals like fish sleep, and fish like us are more evolved than sleep.
Why does sponge release toxins?
The toxins released by the sponge (as mentioned above) can also provide good protection against symbiotic organisms. The sponge is numb and cannot be tasted, seen, heard, smelled, felt (touched). Nervous, they cannot react positively to the surrounding environment.
How does the sponge adapt to the environment?
The sponge skeleton type adapts well to specific habitats and can inhabit hard rock surfaces and soft deposits such as sand and mud. Some sponges can even stick to floating debris! It is rarely completely floating.
How does the sponge respond to stimuli?
Sponges do not have the nervous system or organs like most animals. .. Adult sponges are immobile, but can respond to specific physical stimuli despite the lack of traditional organs and sensory systems. Since the sponge has no nerves or brain, it does not have the ability to cognitively control movement.
Does the sponge communicate?
Sponge cells perform all the functions of organs in higher animals and communicate with each other, a shared ability of all animal cells. .. The sponge also breeds using its pumping. Pump sperm and eggs into the water.
Does the sponge have a nervous system?
It was very surprising that Onur Sakarya of the University of California, Santa Barbara discovered that the sponge carries the beginning of the nervous system. Since there are no speaking neurons, these animals still have a genetic component of synapses, which is one of the most important parts of our nervous system. 2009
Is the sponge sensitive?
Sponges are dynamic and sensitive animals, and it is intuitive to associate these genes with behavior. 2017
