Aquatic Biome of the Caribbean
Transcript of Aquatic Biome of the Caribbean
of the Caribbean By Karly Swezey Overview of the Caribbean The Caribbean islands are located between
the Americas right on the Atlantic ocean just southeast to the gulf of Mexico. Because the islands are located between the two tropics they experience no dramatic change in seasons because the sun is constantly high in the sky throughout the year. the islands are mainly mountainous excluding Aruba which is generally flat large amounts of
volcanic activity Natural Disasters Hurricanes Volcanic eruptions When a hurricane hits, it mixes everything up, resulting in a muddled, more homogeneous upper ocean are left cooler and saltier than before due to amount of fresh cold rain water from the hurricane. The deeper water is left warmer and less salty than it previously was. when volcanic eruptions occur ash and sediment are ejected into the air which then settle in the water. this causes the coral reefs to get buried and sedimentation to occur. corral bleaching and increased disease were also observed along with disintegration of large sponges. coral reefs 8% of the world coral reefs are located in the Caribbean there are about 70 different species of hard coral which attract between 500 and 700 reef associated fish species. coral reefs have more biodiversity than the rainforest. coral reefs are typically found in warmer waters. issues concerning coral reefs in the Caribbean area bleaching and mass mortality of corals can cause total collapse of ecosystem and wide ranging extinction of associated species. coastal zones rapid decline of coral due to global warming and ocean acidification sedimentation occurring because reefs are getting buried by ash and sediment to to volcanic activity increases in surface temperature is destabilizing the coral biome and effecting species populations coastal zones are amongst the most threatened ecosystems because of climate related consequences. sea level rise threatens the stability of coastal areas, its ecosystems, and built environments. coastal zones are constantly changing because to rock erosion and transport of sediment both due to waves. coastal zones are the difference between land and water, these areas are important because the majority of the worlds population inhabits them tides, currents, and waves bring energy to the coast Tides Tides occur due to the gravitational attraction to the moon and the sun on earth the earth bulges towards the moon because it is closer than the sun the rhythmic rise and fall of the oceans surface is due to the tidal bulge moon earth tidal bulge due to inertial forces tidal bulge due to attraction of moon Currents the earths currents are driven by wind, upwelling and down welling near coasts, differences in density, temperature, and salinity between the surface waters and the deep ocean waters. Waves waves have a major influence on the marine environment and ultimately on the planets climate waves are formed when wind blows over the waters surface changing the surface into ripples and waves. as the waves grow in height the wind pushes them along faster causing them to grow in height. waves can become unexpectedly large and destructive. organisms that inhabit the reef the coral reefs provide food, protection, and shelter to hundreds of species of aquatic organisms in the Caribbean. organisms have to adapt with the environment of the coral reef in order to coexist. coexistence between two organisms wrasse fish eats tiny parasites, dead skin, and bacteria attached to the moray eels skin, mouth, and gills. both are benefited from this in that the moray gets rid of unwanted materials and the wrasse gets a free meal. Mutualism symbiosis is a close relationship between two species that benefits at least one of the species. It is an example of coexistence between organisms, but in some cases organisms coexist without interacting and in others organisms must adapt in order to coexist. ALL ORGANISMS ARE PART OF A PREDATOR/PREY RELATIONSHIP organisms are able to coexist and benefit from the reef. commensalism commensalism is a relationship in which one species is benefited and the other is neither helped nor harmed. The sucker fish swim along with the shark for protection and residue from their food. Parasitism parasitism involves one organism living on or inside of another organism and harming it. snails live on and eat away at the coral in the reef. Erosion Erosion is the process by which the surface of the Earth gets worn down. anyone who has ever seen a picture of the Grand Canyon knows that nothing beats the slow steady movement of water when it comes to changing the Earth. coral reefs are destroyed by hurricanes. some organisms evolve with the coral like clown fish and anemone. this is called co evolution. Spotted Scorpion fish The spotted scorpion fish has adapted to it environment in order to capture its prey. Organisms of the Caribbean aquatic biome the hogfish is a commonly targeted species for many spear and reef fisherman and is regarded highly by many for its taste and food value. Hogfish Spiny lobster also known as the rock lobster, spiny lobsters produce rasping sounds to repel predators. striped burrfish smooth trunkfish striped drum white-spotted filefish blue tang dory(: honeycomb cowfish squirrel fish slippery dick coral crab coral crabs hide during the day and come out at night to feed on plankton. cushion sea star sea stars are omnivorous and eat by raking together heaps of sediment and then turns its cardiac stomach inside out and engulfs the mass. seahorse seahorses mat by the female seahorse depositing up to 1,500 eggs in the male's pouch. The male carries the eggs for 9 to 45 days until the seahorses emerge fully developed, then releases them into the water. black tip reef shark barracuda nassau grouper black grouper red hind coney fish barred hamlet palometa orange-spotted filefish filefish are often observed drifting downwards because they are bad swimmers Erosion erosion wears away at rock and forms the land.
