Good day ladies and gentlemen. My name is Crystal. I would like to inform you about some of the threats to our beautiful coral reefs. Imagine that you were doing some deep sea diving and you happen to swim along this beautiful, interesting and colorful wave of wonder made of stony corals and consist of plants, fish, clear waters, and many other creatures. Coral reefs have often been referred to as the rainforests of the ocean and they are one of the greatest wonders of the ocean. Coral reefs…

Beach Nourishment (or also known as beach replenishment) is the process of dumping or pumping sand from another place onto an eroding shoreline or a shoreline in the process of erosion to create, or expand the length and width of the existing beach. However, Beach nourishment does not stop erosion, it just repairs the destruction caused by the tidal waves for awhile. The waves will erode the nourished sand as an alternative instead of damaging houses, roads, recreational spots, or parking lots.…

Geographical processes: Oceans should have a pH level of around 8.2, However has fallen 0.1 pH. If it continues to drop it will be around 7.8 by 2100. Monitoring the pH levels in oceans is extremely important as it affects the marine eco-system (Kolbert, 2016). The Great Barrier Reef is one example of the destruction that ocean acidification can make. Acidification along with ocean warming poses greater threats in coral bleaching. Corals need to sustain calcification so that they can use it…

Jellyfish There are numerous of different species that live in the oceans, from microbes to gigantic whales. Each category of animals has their unique abilities, for example some fishes swim using their fins, while other aquatic animals don’t swim but walk. Of all the variety of marine animals I would like to address jellyfish and their lifestyle since they are very intriguing animals. Jellyfish are a type of zooplankton part of the phylum cnidaria, greek word for “stinging nettle” and the…

The cuttlefish is a very unique animal in its own ways. Its habitat is the ocean but the ocean is home to many other organisms. The Cuttlefish is not a very vicious animal, and it is also not a fighter. There are predators that can eat the cuttlefish, like every organism but like many other organisms it has its very own defense mechanisms. The main defense mechanism of a cuttlefish is its camouflaged skin. It is very amazing because if you put a cuttlefish in bowl with stripes that…

Coral reefs provide shelter and food for more than 1 million plant and animal species, which is nearly one quarter of all known marine species. This number includes over 4,000 species of fish, 700 species of coral, and thousands of other plant and animal forms of life (Cesar, et al.). A single coral reef at its prime contains tens of thousands of species, housing some of the most dense and diverse communities of vertebrate animals in the world. Unfortunately, with the destruction that they face,…

Scales are the exoskeleton covering of the fishes found in most of the cartilaginous and bony fishes which provide protection to the body. Scales are small, thin, cornified, calcareous or bony plates which fit closely together or overlap. Scales are complex derivatives of the integument and are derived from the mesenchymal cells of the dermis. They vary greatly in size, shape, structure, and extent, ranging from rigid armour plates in fishes such as shrimp fishes and box fishes, to microscopic…

Coelenterata - Characteristics of coelenterata are as follows: Coelenterata are creatures that live in the sea although there are some who live in fresh water.Coelenterata included in the class of diploblastik. Exterior body composition has epidermal cells and in the inner layer of gastrodermis. Coelenterata have a difference compared to the porifera where although equally hollow but coelenterata has only one hole for all activities such as eating and as a disposal. Another feature is on the…

A one-of-a-kind place, the Great Barrier Reef located off the coast of Queensland in northeastern Australia, is the largest living thing on Earth. Stretching over 2300km, this largest marine park reserve covers 348,700 square kilometers. Many breathtaking marine creatures call the Great Barrier Reef home including 600 types of soft and hard corals, more than 100 species of jellyfish, 3000 varieties of mollusks, 500 species of worms, 1625 types of fish, 133 varieties of sharks and rays, and more…

Almost all the organisms have adapted their behaviours and biological functions to diurnal and seasonal change in environmental cues such as light-dark cycle, temperature, food availability, etc. (Falcon et al. 2010b). Melatonin is the only chronobiotic molecule which transduces the environmental cues into the chemical signal by rhythmic variation in its release and level. Thus the diurnal and seasonal changes in the circulating levels of melatonin provide the information about the time of day…
