These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011). Sharks have been apex predators in the ocean for millions of years, however, the populations of sharks have been at risk for years as a result of many different factors. The impact of overfishing on shark populations has risen into the public eye over the recent years due to several documentaries and movies that have been released recently. Sharks are particularly vulnerable to over-exploitation due to their K-selected life strategy, having slow growth rates, long life spans and due to them reaching sexual maturity at relatively late age compared to that of other marine organisms (Stevens et al., 2000). Fisherman fish for sharks in order to get their fins, which is used to make shark fin soup (a delicacy in South-East Asia).
Every species had to adapt, evolve, and change to survive the world. Throughout history you can see evolution and how similar every animal is to each other. Some believe that there is no such thing as evolution or adaptation. However, there is so much proof that shows this is not true. Evolution can be seen in the anatomy of animals today.
Swift, strong, stealthy, and fascinating, sharks are marvelous fish. They are well known for their incredible sharp teeth, and vicious behavior. Sharks are extremely unique and an essential part of the ocean and sea ecosystem. There are over five hundred different types of sharks living in the world. Sharks can be divided into two main groups, large and small.
Sometimes the male does too much and it is harassment to the female and then the situation becomes violent. The young bull sharks that are born are free from predators because they stay in the rivers and lakes before they actually go out to the sea and actually try and find a mate. This had made bull sharks one of the most interesting sharks because other sharks can’t harm the young ones and they can grow and become adults without fear of predators such as large sharks. So in a way it’s a protective thing and an evolution
Besides, Islam world had its Golden Age, as history books tell. Dark Age was between 6th and 14th centuries. Islam was not caught in Dark Age at all. In this period, there were numerous inventions that created today’s world technology and knowledge by Islam Golden Age. Ibn Al Haytham had research on finding the light, and he built very first pinhole cameras that has been used many centuries later.
Did you know that the possibly oldest shark may never be completely known? There are shark-like scales dated from 455 million years ago, but there is a debate on whether they are truly shark scales. From the Silurian period, found in Siberia and Mongolia, scales were discovered and there is no debate that they come from sharks. Dated about 400 million years ago, the oldest shark teeth were discovered in Europe. The first “complete”
The time period could be called Golden since older knowledge was preserved and influenced the future. This is true, but medieval culture was restricted to the church, such as the pope and clergy (Doc 11). What came out of the medieval period was good but the period itself was more dark than golden. In conclusion, the three best labels are the Golden Age, the Age of Faith, and the Dark Ages. However, the best label out of the three is the Dark Ages because of the death, corruption, failure, and the invasions.The age of Faith couldn't be the best because the church manipulated their followers.
But this is not the only difference. Marine Biologist gets new information about ocean life every year! In 384-322 BC is when much known marine life today was just found out about. These animals include crustaceans, echinoderms, mollusk, and just fish all together. This information was found out due to the findings of Aristotle’s writings.
The Iron Age is not part of prehistory for all cultures who had introduced written records during the Bronze Age. Most remaining society did so during the Iron Age. In archaeology, the Iron Age refers to the advent of ferrous metallurgy. Ferrous metallurgy involves processes and alloys based on iron. This period coincides with the “Axial Age” in Philosophy.
