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…

The overall objective of the experiment was to find the concentration of phosphate by using spectroscopy. Dilutions of a phosphate working solution with a known concentration were made and their absorption lengths were found using the spectrometer in order to find the concentration of the unknown phosphate sample. INTRODUCTION The goal of the experiment was to find the concentration of an unknown water sample using several standard phosphate solutions’ absorbencies and Beer’s Law. Knowing the…

Comb Jellies are a type of jellyfish that have eight “comb rows” of cilia that are fused together and arranged along their sides. In Figure 1, the fused cilia can be seen easily along the length of the red lines. The cilia are used to propel the animal through the water. Some of them move through the water by doing a flapping motion with their lobes or undulations of the body. They usually have two tentacles, but lack stinging cells. To capture their prey by using sticky cells, called…

Hairy Chested Yeti Crab The hairy chested yeti crab and sometimes known as the Hoff crab after David Hasselhoff, Kiwa tyleri, (Bittel) belong to a group called squat crabs are extraordinary creatures for different reasons. Some including their outer appearance and the way they live in the climates where most other crabs or lobsters couldn’t survive. The white hair body and the spikes on its legs have been due to it adapting to its habitat and climate. (Palermo) Its living conditions are very…

Crabs are a type of crustacean that occur within mangrove ecosystems and can be found from high tide through to low tide levels. Crabs shelter underneath logs and in cool places to avoid drying out and many create burrows for refuge from larger prey, it can also be the site of mating and incubation. Other crabs use burrows to store their food as the water tide rises or lowers. Red fingered marsh crabs and fiddler crabs are commonly active at low tides where they are often out looking for food,…

These polyps get 90% of their energy from small algae called zooxanthellae which also produces their colour. Bleaching occurs when the polyps get rid of the zooxanthellae which leaves the clear polyps on top of a coral skeleton (a calcium carbonate skeleton which is built underneath most corals). Without…

Not only is water one of the key parts of life but it is the home to many animals such as fish and crabs of course the ocean is home to alot more animals but the lakes and rivers are just as in portinten they are home to a lot of animals such as bluegill and catfish the lakes and rivers are 0.0081%of the earth's waters which is a really really really small small amount the oceans make 96.8%of the world's water which is really really big amounts of water the only bad thing about that is that it…

effects on the world, but it especially has an impact on the ocean. Global temperature rise can affect many ecosystems, and the species within them. Coral Reefs Coral reefs are valuable resources for ocean life. Coral and algae have a symbiotic relationship, with the algae living in the coral and being the primary food source for the coral. As a consequence, this symbiotic relationship provides habitats for small fish and plants due to the abundance of food found in the coral. Many species…

Emperor Angelfish (Pomacanthus imperator) Introduction: The Emperor Angelfish (Pomacanthus imperator), is a reef-associated marine angelfish and is also called the Imperator Angelfish or Imperial Angelfish. Because of their beautiful color and attractive shape, the species is among the most amazing underwater fish in the Red Sea or in the aquariums. It is possibly the most easily recognized fish in the Red Sea. The display which the species make is marvelous whether done in the wild or in…
