Coral reefs are undeniably important for numerous reasons. They are ecologically important by supporting and providing habitat for marine community, act as wave-breakers to protect the shores from strong currents, generate income for humans and provide many other ecosystem services (Sutton 1985, Demirbilek and Nwogu 2007, Moberg and Folke 1999). Yet, corals reefs around the world are increasingly being destroyed at an unprecedented rate through overfishing, fish-bombing, increasing coastal development
Sirenia is a small order consisting of two major families namely Dugongidae and Trichechidea. The family Trichechidea has three species namely : West Indian Manatees (Trichechus Manatees) , African Manatees ( Trichecus senegalensis ) , Amazonian manatees (Trichechus inunguis). There is stand out surviving part of family Dugongidae, dugongs (Dugong dugon). They are large aquatic mammals with tapering to paddle like dorsoventrally flattened bilobed tails .The order Sirenia is based on sirens i.e
Chitons are a class of mollusc called Polyplacophora, when examined, share the same anatomical features as those of the first molluscs on earth. This means that they are t closely related to the beginning of the mollusc group. These molluscs vary in size but have the same features as a long, oval flat body with a segmented mantle to protect the ventral of the chiton. These organism have learned to create a “suction” affect using their ventral to hold on to rocks so that they do not get washed away
There are seven characteristics which make organisms different from non living things. These characteristics include growth, reproduction, irritability, movement, nutrition, excretion and respiration. The starfish is considered to be alive because it portrays the seven characteristics of a living organism. A starfish is considered to be undefined. It is continuously growing and all cells preserve the aptitude to develop into whatever section is considered necessary. several variety of starfish encompass
The deep green pool of the Salinas River was still in the late afternoon. Already the sun had left the valley to go climbing up the slopes of the Gabilan Mountains, and the hilltops were rosy in the sun. But by the pool among the mottled sycamores, a pleasant shade had fallen. A water snake glided smoothly up the pool, twisting its periscope head from side to side; and it swam the length of the pool and came to the legs of a motionless heron that stood in the shallows. A silent head and beak lanced
Why should endangered species be protected by humans? People should know that animals and plants are creature that have the right to live in peace. Endangered species are animals and plants that will be extinct because of human activities such as hunting. Some people would use many kind of animals to take their leather and use to it as clothes, bags, and shoes. Also, humans are cutting plants in a suspicious way without thinking about this act and how it may affect nature. Due to this horrible action
Puerto Rico where I became involved in marine conservation projects. I periodically volunteered in fieldwork with Alex Mercado (PhD Candidate) on the current population status of the sea urchin Diadema antillarum and its role in the recruitment of coral. My collaboration in this research consisted of monitoring and counting Diadema antillarum on specific reefs. During my second semester as an undergrad student, I took General Biology II with Dr. Anabella Zuluaga (Marine scientist). Dr. Zuluaga introduced
Introduction: Daphina are planktonic crustaceans that belong to the class Phyllopoda(Branchiopoda) to which flattened leaf-legs used in producing a water vcurrent for their filtering apparatus. In the brachiopods, Daphnia belong to the order Cladocera whose bodies are encloosed by carapace, which is made up of chitin and polysaccharide. The carpace forms double wall separates hemolymph anda part of body cavity.Animals which belong to the order Cladocera, have up to 10 pairs of appendages, which
saltwater clam or mollusk with a shell. Some oysters are also sometimes referred to as scallops. They have a single muscle called the adductor muscle which can also simply be referred to as scallop when sold as a meat, however, the ovary known as roe or coral can also be eaten. Scallops
Anemone fish, also called clown fish, live nestled among the tentacles of stinging anemones. Scientists have found that these fish have a special layer of saliva that keeps the anemones from stinging them. Clown fish need the security they find in their anemones: the anemones' stings keep fish predators away, and a clown fish never lives without its host anemone. The partnership may benefit the anemones, as well they get scraps of food dropped by the Clown fish as they eat. And the aggressive and
Red tides Red tide is a generic term for harmful algal bloom or HAB. Red tides occur as a result of explosion of algae population such as dinoflagellates. The expansive population concentrates along the water column and cluster in one area of the ocean, this results in the change of color of the surface water. Red tides occur along coastal areas. Color: Red tides are not necessarily always red. The color may vary from deep shades of red to pink, orange, brown or even yellow. http://www.livescience
Angler fish is a bony fish from order of Lophiiformes. There are 18 families, 5 suborders and more than 200 species of anglerfish. Most angler fish around the world live in the bathypelagic zone of the Atlantic and Antarctic oceans. They can survive up from 1000m to 4000m below the surface, although some live in shallow waters too. (National Geographic) Most of the angler fish are generally dark grey to dark brown in colour, they have huge heads and enormous crescent-shaped mouths filled with sharp
I. INTRODUCTION The ocean is undoubtedly one of the most valuable resources known to humans. It is sometimes called as The Big Blue or The Great Provider. Ever since, people have taken advantage of the many benefits our ocean presents us with. It’s been used as a source of food and as a source of many minerals. However, unfortunately, what seemed to be impossible a hundred years ago is happening. Sadly, the existence of this great body of water is being threatened. Unfortunately, people
II. FACTORS CAUSING THE DECREASING OF OYSTER REEFS. Nowadays in many literature are represented the most important threats for oyster beds, as overharvest, development and pollution, changes in freshwater inflows, erosion from boats, diseases, invasive species, global change… (Coen et al. 2000; Seavey et al. 2011; Gregalis et al. 2008; Piazza et al. 2005). 1. Overharvest. Overharvest is one of the major threats to oysters worldwide (Beck et al 2011; Seavey et al. 2011). At the beginning of oyster
Often called the rainforests of the ocean, coral reefs are a vital source for this planet. They provide a buffer, protecting our precious coasts from catastrophic storms, horrendous waves, and damaging floods. Coral reefs provide and form an amazing barrier to protect our sandy or rocky shorelines from everything bad in the questionable ocean. Not only do they protect us humans from flooding, erosion, and everything else that is bad from the ocean. These coral reefs that you see in pictures and on television
2 .Habitat 2.1 Population Information The Black-browed Albatross is a marine species that inhabits Antarctic, subantarctic and temperate waters and occasionally enters the tropics . It can tolerate a broad range of sea-surface temperatures from 0–24º C or probably more based on occasional records from the tropics. It forages around the breaks of continental and island shelves and across nearby underwater banks, but also frequents other marine habitats, such as oceanic waters and the iceberg belt
Flinders Island Tasmania Next up in Tasmania we head for Flinders Island which is the main island of the Furneaux group, a collection of 52 islands stretching across Bass Strait between Tasmania and mainland Australia. There is much to do and explore on this island. Visit Wybalenna one of the most historic sites in relation to Tasmanian Aboriginals and the Furneaux group. The graveyard has unmarked aboriginal graves as well as graves of some of the first European settlers. In the cemetery the Young
Green Sea turtles are also called Pacific Green turtles and Black Sea Turtles. Its scientific name is Chelonia mydas. It belongs to the family ‘Cheloniidae’ and genus ‘Chelonia’. This species is found in the seas of tropical and subtropical areas. It has two diverse populations in Atlantic Ocean and Pacific Ocean. Green sea turtles have flattened bodies which are covered by big carapace. They have two large flippers. Their colors are light but the species that are living in the eastern Pacific
AP Environmental Science: Chapter 5 1. Explain how southern sea otters act as a keystone species in kelp beds. The otters help to keep sea urchins and other kelp-eating species from depleting highly productive and rapidly growing kelp forests, which provide habitats for a number of species in offshore coastal waters. Without southern sea otters, sea urchins would probably destroy the kelp forests and much of the rich biodiversity associated with them. Explain why we should care about protecting
Adaptations allow deep-sea creatures to survive in extreme environments. There are many different adaptations that allow an animal to survive. The three common adaptations consist of habitat, appearance, and diet. The Giant Squid, Zombie Worm, and the Yeti Crab utilized these adaptations to survive, and without them it would be difficult to nearly impossible to keep their species alive and flourishing. Each one of theses species is suited for its environment and survival tasks through its adaptations
