Coral reefs come in many different sizes and shapes. They are located all over the world but are very sensitive to the temperature and chemical composition of the water. Majority of all coral reefs are located in the tropics. The largest coral reef is the Great Barrier Reef, which is located in the Coral Sea near Australia. The length of the Great Barrier Reef is 1,553 miles long.
Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
Therefore the Megladon fish is a laterally compressed fish which allows it to live in dense covers or coral reefs. Laterally compressed fish make the fish flattened side-to-side. The coral reefs of Jamaica are vibrant and full of fish. The Megladon's body shape is efficient enough to allow burst of speed, escape from predators as well as fit into small spaces. They have two pectoral fins that are forked in on the sides which enable them to control their direction of movement.
MARINE BIOMES Introduction The marine biomes, which are saltwater environment, are the biggest biome in the world. It covers about 71% of the earth. Marine biomes form a category of aquatic biome uniting estuaries, oceans, seas and coral reefs. Did you know…? The marine biome is located by the ocean or sea in lots of places.
There are also coral reefs off the coast of Florida, USA, to the Caribbean, and down to Brazil. The Great Barrier Reef (off the coast of NE Australia) is the largest coral reef in the world. It is over 1,257 miles (2000 km) long. Types of Reefs: The different types of reefs include: Fringing reefs are reefs that form along a coastline. They grow on the continental shelf in shallow water.
INTRODUCTION Nereis succinea (commonly known as clamworm) are in Class Polychaeta. N. succinea belongs to a free-swimming group of worms. They have bristle like appendages which are used for respiration and allow them to swim or crawl along the sea floor (Campbell, 2008). N. succinea is ubiquitous in number and commonly resides in estuaries. Some species can also be found around mudflats and sand flats which are high in salinity.
They teach the local students about the environmental concerns linked to the marine ecosystem. Field work is common for this job. The study of saltwater organisms and their relationships to their environment is also a job a marine biologist will be doing. Subject areas are almost limitless. They also study the population fluctuation in different fish.
The uplift was surrounded by an epicontinental sea where sediment accumulated in marine margins creating sandstones, siltstones and limestones throughout the Basin. Facies 1 in the carbonate unit consists of 4-34 cm beds of black micrite, matrix supported with less than 5-10% grains making it a mudstone; crystalized shell fragments are present, 2-4 mm bivalve bioclasts and sparse 3-5 cm rugose coral and crinoid fragments; horizontal inclined burrows are
Some species of sea anemone are capable of moving slowly by sliding along the substrate on their pedal discs (Parker, 1916). Certain families of sea anemone even possess the ability to swim by lashing their tentacles in a coordinated fashion, such as sea anemones in the family Boloceroides (Lawn & Ross, 1982). On the other hand, feather stars usually move by extending their arms and pulling themselves along the seabed ("Feather stars (Crinoidea) on the Shores of Singapore"). They can also swim with upward and downward strokes of their arms (Moore & Overhill,
They are a source of protection for small organisms. They also help because their roots filter nutrients that flow from the land into the ocean, and produce the amount of erosion that occurs. This is influential, especially to coral reefs, because it is reducing the amount of nutrients, preventing the production of algae blooms that block the much needed sunlight. Mangroves can significantly slow the wind forces down along the coasts before they reach land, making them a strong defense against hurricane winds, tsunamis, and tornadoes. There are different types of mangroves; red, white, and black.
