        According the website Animalia, t he Brown-throated sloth is the most common of the four three-toed sloth species. It is native to the rainforest canopies of Central and South America. The Brown-throated three-toed sloth is a unique mammal that is the slowest in the world. 'Sloth' is the word for slow. They are able to eat leaves that are too high for other animals to reach because they are able to hang onto branches with their long claws. However, these long claws make it difficult for them to walk on the ground. As a result, the Brown-throated three-toed sloths spend the majority of their time in trees.      The body of the Brown-throated sloth is covered in grayish-brown to beige fur, with darker brown fur on the forehead, sides of the face, and throat. The hairs are unique in that they have many tiny fissures all over their surfaces and no central medulla. Several commensal species of algae live in these fissures. In young sloths, the ...

     "The nearer we approach the tropics, the greater the increase in the variety of structure, grace of form, and mixture of colors, as also in perpetual youth and vigor of organic life," German naturalist Alexander von Humboldt wrote in 1807.  In tropical climates, the concentration of plant, animal, and fungal species decreases away from the equator, with more species found in any given area.      Energy is the basis for the first hypothesis that why tropics has more species. In the tropics, there is greater sunshine, which increases plant growth when paired with rainfall and nutrients from the soil. From the standpoint of evolution, more plant diversity results in a wider variety of creatures.       The second hypothesis determines that because the tropics are older habitats that have not seen frequent freezing temperatures, organisms have had more time to evolve there.  Although it has been impacted by several ice ag...

    According National  Ocean Service, climate change had changing the ocean, coral reef ecosystems are significantly impacted by these changes.The biggest threat facing coral reef ecosystems globally is climate change. The warming of the Earth's atmosphere and oceans is now undeniably supported by scientific evidence, which also shows that greenhouse gases produced by human activity are principally to blame for these changes.      Mass coral bleaching episodes and infectious disease epidemics are occurring more frequently as temperatures rise. Additionally, by changing the chemistry of seawater by lowering pH, carbon dioxide absorbed into the ocean from the atmosphere has already started to slow down the rate of calcification in animals that create reefs and are connected with reefs. It is known as ocean acidification.      Climate change may induce an increase in sedimentation for reefs located near land-based sediment sources. Coral may b...
