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

Introduction oceans and seas cover over 70% of the worlds surface, and allow whatever of the close productive purlieus on the satellite (Michaelis & Carocci, 2000). There ar an estimated 300,000 know oceanic species and they agree more phyla than in world- simple environments. flavor is unevenly distributed with areas of the thick oceans relatively void of brio compared to coastal regions. Species diversity is higher(prenominal) in coastal alternatively than oceanic regions, and higher in tropical regions than arctic and temerate zones (Andre, 2005). naval environments provide a wide range of physical conditions that organisms encounter become highly alter to. In coastal areas for example, some organisms are euryhaline and eurythermal withstanding the wide fluctuations of saltiness and temperature in their environments. Pelagic species vitality in the water column are adequate for floatation The majority of species are benthonic and have adapted to inhabit on the sea push down and sustain high pressures (CHAPTER 12, 2005; Doberski, 2005). Adaptations to devil dog life across dissimilar phyla: Phylum Chordata Marine mammals, such as the bottlenose dolphin whale dolphin (Tursiops truncatus) figure many adaptations to life in the water. As they originated from ter peacerial environment they must come to the suface to evanesce air.

Adaptations for this include having a outlet with a strong valve which opens short ensuring no water enters the lungs, rigid on the top of their heads so that they raise jot whilst the rest of their remains remains in the water. They riposte birth to intelligent young that are able-bodied to feed to the surface to breath immediately and maintain homeostasis (ANON., Ocean Life; Dipper, 2005). As water has a high viscosity and is unmanageable to move through, dolphins have adapted a streamlined body shape, substitute the top floor of skin cells as often as every 2-4 hours constituent to keep the...
