These would most likely be the first fish to occupy Earth, having diversified from the primitive crustaceans that occupied the sea beforehand. These primitive and relatively unspecialized organisms would have adapted over a long period of time (millions of years) to take into account the factors above.</p><p>Also, as competition increased and available habitats decreased, fish would have had to be more aggressive or more co-operative in their nature to survive in the long term. This has led to species like the shark, which is of phenomenal size and represents danger.</p><p>Other species have taken a different approach, adopting chemical defenses as a means of survival. Others have adapted to occupy very low altitudes, thus avoiding some of the more competitive habitats closer to the water surface.</p><p>All in all, fish, alongside the later developing mammals, would successfully dominate the seas. In the future, mammals would occupy the sea from land, but fish did the opposite; they evolved from the sea on to land just like the <a href=https://www.biologyonline.com/dictionary/arthropod/ data-wpel-link=internal rel=follow>arthropods</a> intended.</p><p>&nbsp;</p><p>&nbsp;</p><div style="text-align: center; vertical-align: top; padding: 10px; border: 1px solid #e2e2e2;"><iframe src=https://www.youtube.com/embed/E1h4kgt2520 width=560 height=315 frameborder=0 allowfullscreen=allowfullscreen></iframe></div><div style="vertical-align: top; padding: 10px; border: 1px solid #e2e2e2;">Credit: <a href=https://www.youtube.com/channel/UCzR-rom72PHN9Zg7RML9EbA data-wpel-link=external target=_blank rel="nofollow external noopener noreferrer">PBS Eons</a></div> <script>if(window.qmn_quiz_data===undefined){window.qmn_quiz_data=new Object();}</script><script>window.qmn_quiz_data["66"]={"quiz_id":"66","quiz_name":"Fish - Quiz","disable_answer":"0","ajax_show_correct":"0","progress_bar":"1","contact_info_location":"1","qpages":{"2":{"id":"2","quizID":"66","pagekey":"Ikl3Ohpn","hide_prevbtn":"0"}},"skip_validation_time_expire":"1","timer_limit_val":0,"disable_scroll_next_previous_click":"0","disable_first_page":0,"enable_result_after_timer_end":"0","enable_quick_result_mc":"0","end_quiz_if_wrong":0,"form_disable_autofill":0,"disable_mathjax":0,"enable_quick_correct_answer_info":0,"quick_result_correct_answer_text":"Correct!
