There are unusual creatures that have inhabited our planet for at least 500 million years who spend a portion of their lives as plant-like polyps before transforming into some of the greatest ocean predators‚ all without having any brain‚ heart‚ backbone‚ eyes‚ ears or teeth. Cnidaria‚ otherwise known as jellyfish‚ are gelatinous animals found at all depths within all oceans around the world‚ and are some of the oldest animals evolutionarily speaking. Jellyfish are rather simplistic‚ anatomically

Global Warming Global warming occurs when the levels of greenhouse gasses rise and less infrared light‚ or heat‚ escapes the earth’s atmosphere. Thus‚ the temperature experienced on Earth begins to rise. Climate change is a part of the Earth’s history. There have been dramatic fluctuations in overall average temperature for the past 150‚000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with carbon dioxide level

Sex: Testes function only in a narrow range of temperature. (Those of mammals hang externally in a scrotal sac because internal body temperatures are too high for their proper function.) A worldwide rise in temperature at the close of the Cretaceous period caused the testes of dinosaurs to stop functioning and led to their extinction by sterilization

The biology of the sea turtle and facors affecting its population Upon first sight of the great sea turtle it might just think that it is like any other turtle. The truth is that marine turtles are beautiful creatures spending a majority of their lives wandering endlessly through our massive ocean. These reptiles have the ability to do amazing things. Some of these things include evolving to a range of purely innate responses to the demands of a changing suite of environments and having remarkable

over 3‚000 sea lion pups‚ at a point teetering towards death‚ washed ashore on Southern Californian beaches‚ fifteen times more than in past years‚ due to toxic algal blooms. Merriam Webster calls algal blooms‚ “rapid and excessive growths of a plankton population.” Since 1998‚ scientists have been aware of sea lions and their pups being intoxicated by domoic acids from toxic algal blooms. Agricultural and suburban areas are the main culprits as excess fertilizer and pesticides from fields and lawns

phytoplankton because zooplankton and phytoplankton produce 80% of our oxygen it is important to keep them alive. If we did not have sharks the other fish populations which will be overcrowded because sharks have been overfished‚ they will eat all the plankton‚ and we would lose a large source of oxygen. Overfishing also has large impacts on the economy which can be seen in our home state of Maryland where oysters have been overfished and because of this has significantly hurt the local economy because

Sea anemones are members of the Phylum Cnidarian. The cnidarians include the anemones‚ jellyfish‚ coral‚ Portuguese man-of-war and hydroids. Their characteristics include a soft body with two tissue layers arranged around a central gut cavity. A ring of tentacles surrounds a central mouth‚ and the tentacles endure stinging cells which contain nematocysts used to capture food and for defense. ("Marine Life Profile: Sea Anemones”) The two basic body forms among the cnidarians are the polyp‚ which looks
