Sea Lion‚ spends a great majority of its day in the water hunting for prey‚ however it does not venture out very far from its territory due to the fact that their main predators tend to be there. Their prey is primarily fish‚ squid‚ octopus‚ and crustaceans‚ and predators are sharks and killer whales‚ but humans are not a threat now. Pursuing this further‚ humans were a prodigious threat previously when sea lions of all kinds were hunted for meat‚ skin‚ and oil. Luckily‚ though hunting of this species

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

penguins are heavy so they can swim and dive for food. A penguins wings are paddle like flippers. Their legs and webbed feet are used as rudders‚ for steering. What do penguins eat?

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

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
