What is Commensalism : Biology Blog

                                        Commensalism 



Commensalism is the interaction between two species where one species is benefitted and the other is neither harmed nor benefitted. Mostly this type of phenomenon happened in one larger community and one smaller one. We can understand this by taking some examples like -


  • an orchid growing as an epiphyte on a mango tree. Orchids get shelter and nutrition from the mango tree, while the mango tree is neither benefitted nor harmed.
                                                   
  • Sea- anemone has stinging tentacles and the clownfish live among them. The fish get protection from predators, which stay away from the stinging tentacles. The anemone does not appear to derive any benefits by hosting the clownfish.
                            
  • The Monarch butterfly stores poison chemicals from the milkweed plant in its body. the chemicals make other animals who might eat the monarch butterfly sick. So the butterfly uses the milkweed for protection.

                                     Canal system in Sycon  A sea creature called a sycon, or scypha , is usually found clinging to rocks or other surfaces. These creatures have tube-shaped bodies that open outward with the help of a hole called an Osculum . They have tiny openings called Spiracles and Ostia all over their bodies to let water in. This water flows through canals inside their bodies and comes out through the Osculum, which is a larger opening used for breathing. We'll observe the shape of this canal system, why it is essential for those animals, type of canal system , and  its significance. The Sycon Type Canal system is the unique feature of the phylum Porifera . This system is also known as the  aquiferous canal system . This system supports the significant function of the body like nutrition, respiration, excretion, etc. History Overview -  Gran...

                                             Types of Egg Hello guys! We'll examine a crucial area of zoology in this blog: different varieties of eggs. So let's define reproduction first before moving on to the subject. Reproduction is the biological process in which a parent is responsible to produce their offsprings which may be of their own kind. Reproduction is a must process for every individual for the continuing existence of the species. As we all know, there are many different species on the planet, and each of them has a unique method of egg production and inside the egg they contain yolk . The yolk is composed of proteins, fats, vitamins, and minerals, which are vital for the growth and development of the embryo.  Eggs can be classified into different types based on the amount of yolk they contain. l.  On the basis of the amount of Yolk - Dep...

They're usually between 2 to 15 inches wide. Even though they prefer being alone, they get carried together in groups called Blooms by wind and water currents. At night, they look like they're moving through the water like jellyfish, which is why they're sometimes called " jellyfish ".  They have four reproductive organs surrounded by tentacles in their top part. Their body color changes based on what they eat, so they can be blue, pink, or other colors. Let's learn more about Aurelia in detail. Details Of Aurelia Diagram -  Body : The center of the diagram would display the jellyfish's bell-shaped body, often called the " umbrella. " Tentacles : Below the bell, you'd see lon...
