Triops are very tiny crustaceans known as living fossils (Velazo 1) and are evolved where there was not a lot of water. Also‚ they would randomly eat their own eyes. Triops are good to observe in science because they are fun to watch and students can learn their charm characteristics (Ansberry). They also have are very high structure making them high in genetic drift but low in gene flow (Zierold). Our Biology class studied the triops by observing how long they swam between the colors: black and

as snails‚ shrimp‚ crabs‚ tube worms‚ fish‚ and octopuses form a food chain of predator and prey relationships above the primary consumers. The main families of organisms found around seafloor vents are annelids‚ poginophorans‚ gastropods‚ and crustaceans . Hydrothermal vents in the deep ocean typically form along the Mid- ocean ridges‚ such as the East Pacific Rise and the Mid- Atlantic Ridge. These are locations where two tectonic plates are diverging and new crust is being formed. The hydrothermal

We went to the Conodoguinet Creek to test the pollution levels of the creek. My hypothesis was If we check the pollution levels in the water‚ then we will find out that the water isn’t very polluted. You may be wondering‚ what are some of the causes of pollution? Well‚ the velocity of the water has a lot to do with the health. When the velocity of the water is faster‚ everything will be moving around more and there will more more dissolved oxygens. the mud and sediments won’t just stay there and

The crocodile eats almost anything. The young eats small fish‚ snails‚ crustaceans and insects. The adults eat fish‚ crabs‚ turtles‚ snakes‚ and small mammals. The American alligator young eats small invertebrates‚ insets‚ small fish‚ and frogs. Adults eat fish‚ turtles‚ mall mammals‚ birds‚ reptiles‚ and small alligators. The

they gain structural support for their bodies in different ways. For example‚ sea anemones have a hydrostatic skeleton that produces support via sheets of muscles and an internal cavity filled with fluid. Other invertebrates such as insects and crustaceans have a hard outer shell or exoskeleton. An estimated 97% of all species are alive today are invertebrates. Of all invertebrates‚ the insects are by far the most numerous. There are so many species of insects that scientists have yet to discover

invertebrates (with or without backbone.) Animals with blood were subdivided into ones that gave live birth (mammals)‚ or ones that gave birth via egg (fish and birds). The animals without blood were then subdivided into insects‚ mollusks‚ and crustaceans‚ which were then divided into those with and without shells. The Swedish botanist Carolus Linnaeus is regarded as the father of taxonomy‚ as he developed a system known as Linnaean classification for categorization of organisms and binomial nomenclature
