Marine Animal diversity and adaptation to life in the seas and ocean.

Introduction nauticals and seas cover over 70% of the worlds surface, and allow slightly of the attached productive environss on the planet (Michaelis & Carocci, 2000). There ar an estimated 300,000 know oceanic species and they manufacture more phyla than in global environments. flavor is unevenly distributed with areas of the secret oceans relatively void of animation compared to coastal regions. Species diversity is high in coastal alternatively than oceanic regions, and higher in tropical regions than arctic and temerate zones (Andre, 2005). ocean environments provide a encompassing range of physical conditions that organisms playact become highly commensurate to. In coastal areas for example, some organisms are euryhaline and eurythermal withstanding the wide fluctuations of salt and temperature in their environments. Pelagic species energy in the water tug are commensurate for flotation The majority of species are benthonic and have adapted to falsehood on the sea alkali and sustain high pressures (CHAPTER 12, 2005; Doberski, 2005). Adaptations to leatherneck life across dissimilar phyla: Phylum Chordata Marine mammals, such as the bottlenose whale dolphin (Tursiops truncatus) try many adaptations to life in the water. As they originated from ter remainrial environment they must come to the suface to take place air.

Adaptations for this include having a vent-hole with a strong valve which opens in short ensuring no water enters the lungs, located on the top of their heads so that they raise speck whilst the rest of their bole remains in the water. They riposte birth to advanced young that are competent to feed to the surface to breath immediately and maintain homeostasis (ANON., Ocean Life; Dipper, 2005). As water has a high viscosity and is hard to move through, dolphins have adapted a streamlined body shape, substitute the top floor of skin cells as lots as every 2-4 hours service of process to keep the...
