The most primitive set detects only light levels, but one set of eyes is more sophisticated and can detect the color and size of objects. ... Whilethe jellyfish could avoid objects of different colors and shapes, transparent objects proved more difficult. “They can't respond to the see-th...
It is only a small jellyfish as its bell can only be measured about four inches (10 cm) in diameter.Scientists were astounded by the discovery of this species, as it can survive under harsh environments such as low oxygen levels and high acid content. It acquired its name from its shape...
Winds can also influence how high the tides come in. Then there are the climate patterns like El Nino (厄尔尼诺现象), which lead to higher-than-normal sea levels along both the U. S. East and West coasts. And, of course, the most powerful driver is sea level rise itself. Because of...
Another popular Jelly fish is the Upside Down Jelly fish, Cassiopea, which comes from the western Pacific Ocean around the Philippines and has been introduced to Hawaii (probably by ships around World War II). Cassiopea grows to about 8 inches / 20 cm in diameter. They are interesting because...

caused by excessive nutrients from sewage and fertilizer runoff, and jellyfish eruptions. One example is the waters off the southern United States coast. Nutrient-enriched waters from the Mississippi River have created in the Gulf of Mexico a massive dead zone (ocean area with low oxygen levels)...
In addition, scientists predict that the reduction of marinephytoplanktonpopulations due to rising pH levels in the oceans will produce a positive feedback that intensifiesglobal warming. Marine phytoplankton produce dimethyl sulfide (DMS), a gas that serves as the most significant source ofsulfurin ...
Perhaps the most damaging type of jellyfish increase in recent decades has been caused by populations of new, nonindigenous species gradually building-up to 'bloom' levels in some regions. Lest one conclude that the next millennium will feature only increases in jellyfish numbers worldwide, ...

The shape of the ocean also is altered assea levelschange. During ice ages a higher proportion of the waters of theEarthis bound in the polarice caps, resulting in a relatively low sea level. When the polar ice caps melt during interglacial periods, the sea level rises. These changes in...
