Chris Chapman Dr. Karen Keane-Hines Anatomy &Physiology II MANATEE Long ago manatees were mistaken for mermaids or sirens-luring sailors to their deaths on rocky shores. So the order of these marine mammals has been named, Sirenia. There are five species: Amazonian, West African, and West Indian with two sub-species the Florida and Antillian Manatee. All have front flippers and a solid, flat, paddle shaped tail. Another related species, the Dugong, has a fluked tail.
The IRL serves as both a spawning ground as well as a nursery for many species found in both lagoon and ocean settings. The IRL contains in excess of 4000 animal as well as plant species, including manatees, dolphins, coastal birds, sea turtles, mangroves, and many species of sea grass. Approximately 35% of the country’s population of manatees resides in or regularly migrates through the lagoon. The IRL’s bird populations are among the largest in North America (Dybas, 2002). The IRL is both a unique, and diverse, shallow-water estuary of national significance and makes up approximately 40% of Florida’s east coast.
The plants release dissolved oxygen and harbor fish and shellfish (Franklin, 2001). They swim in large schools close to the water’s surface. Throughout the spring, the schools of younger, smaller fish are found in estuaries, such as the Chesapeake Bay, and the larger, older fish are found further offshore and up north. Menhaden also play an important role to the fisheries, especially along the Atlantic and Gulf coasts. Humans don’t actually
These reptiles have the ability to do incredible things. The Green Sea Turtle is one of seven species and happens to be the largest member of the Cheioniidae family. According to www.turtles.org/hawgrnd.htm , scientists assume that post-hatchlings, pelagic-stage Green Sea Turtles are omnivorous, but there are no data on diet from this age class. Young Green Sea Turtles have a diet of jellyfish and other invertebrates. Adults tend to eat sea grass and algae.
They need to feed their chicks and the colonies are often a long way from the fishing grounds. Each chick needs about 42 kg of food from each parent.The entire breeding population of emperor penguins may consume as much as 1,500,000,000 kg (1,500,000 metric tons) of krill, 115,000,000 (115,000 metric tons) of fishes and 3,500,000 (3,500 metric tons) of squid each year. Method Of Collecting And Eating Food Penguins feed at sea. Most feeding occurs within 15.3 to 18.3 m (50-60 ft.) of the surface.
other crocodiles, the gharials feed on warm-blooded species and can grow to 7 m in length, the gharial has a thick skin. Their found in rapid current and it can swim all thro that to think of that going that fast on such a current is amazing and lagest of all crocodilians. They have a narrow snout so pretty cool and extremely sharp teeth and 54-58 on the top and 54 on the bottom found on the back waters of large rivers and feed almost exclusively on fish and theur eggs take 90 days to emerge and it also on larva and it finds to be one if the they are between 4 and 6 millimeters in length and live about 40 to 60 it's pretty much all places and comes from all the places and it's French Spanish I think I don't remember if I wrote that but it's pretty impressive and i like this animal and it's a reptile and it can grab the fish easy and cool to study and looks out couldn't pick a better animal to study about only thing that can be so hard to talk about it so late at night and morning and it's fun though glad I'm about to pick a animal to talk about it hope I don't have to stand up and talk to the whole class but I just saw a picture it looks like it's got a wart on its nose not judging but it's just ugly sight to see don't look it up I can pull up a picture but it's not worth looking at just save
Olive Ridleys get their name from the coloring of their heart-shaped shell, which starts out gray but becomes olive green once the turtles are adult. Hatchlings are dark gray with a pale yolk scar, but appear all black when wet. Carapace length ranges from 37 to 50 mm. Olive Ridleys are omnivorous, meaning that they consume a varied diet from both plant and animal sources. Distribution Although Olive Ridleys spend time in the open ocean, they also forage in coastal waters and estuaries.Olive Ridley turtles are found only in warmer waters, including the southern Atlantic, Pacific and Indian oceans.
Yao Lin Research Paper The Effects of Human Activity on Marine Wildlife Earth is the only planet in the entire universe that currently has the capability to house living creatures. Considering that 70% of this planet is covered in water, one would think the creatures inhabiting the planet would treat the water with the upmost care. However, this is incorrect. Homo sapiens, the most intelligent species on the planet, tend to treat the oceans as a place to retrieve free raw materials and a personal waste disposal. During human’s 200,000 year existence on earth, this species has managed to completely undermine the ecosystem of the marine world by introducing alien species to a certain habitat, destroying marine habitats, over-harvesting fish, and polluting the waters.
Elevated pH can in turn ‘blind' organisms that rely on perception of dissolved chemical cues for their survival by impairing their chemosensory abilities (Figure 3) (Turner & Chislock 2010). When these dense algal blooms eventually die, microbial decomposition severely depletes dissolved oxygen, creating a hypoxic or anoxic ‘dead zone' lacking sufficient oxygen to support most organisms. Dead zones are found in many freshwater lakes including the Laurentian Great Lakes (e.g., central basin of Lake Erie; Arend et al. 2011) during the summer. Furthermore, such hypoxic events are particularly common in marine coastal environments surrounding large, nutrient-rich rivers (e.g., Mississippi River and the Gulf of Mexico; Susquehanna River and the Chesapeake Bay) and have been shown to affect more than 245,000 square kilometers in over 400 near-shore systems (Diaz & Rosenberg 2008).
Many different kinds of fish live in the reefs as their haven for feeding, reproduction, and safety from predators. Without an ecosystem to live in, these fish species will become extinct. Ten percent of the world's reefs have been completely destroyed. Coral reef destruction is the worst, over 70% have been destroyed and only 5% can be said to be in good condition. What has happened to destroy so many reefs?
