Ophiothrix spiculata (a.k.a. spiny brittle stars) are the most diverse organisms in phylum Echinodermata that can be found in the ocean all over the world. They are spotted in many different colors such as orange, yellow, red, blue, black, or even tanned with reddish and white bands on their arms. Most spiny brittle stars have either round or star-shape body that are usually not larger than three centimeters. The body is called the central disk which consists of the dorsal shield (aboral side) and oral shield (oral side.)…
The Utah Lake Sculpin was a pinkish transparent color. The fishes main food source was invertebrates. This fish was a freshwater species. The Utah Lake Sculpin was a bottom dwelling fish, which means it lived on the bottom of the lake (Cottus echinatus)). The environment this fish lived in was rocky, shallow areas in the Utah Lake.…
The steelhead trout used to be a native species to the Arroyo Del Valle in Pleasanton, California. Some are anadromous fish (i.e. they spend most of their time in freshwater developing after they hatch and then spend part of their later life in the sea or ocean) but others will remain in a freshwater stream or creek their entire lives. Typically, anadromous populations swim up the creek in winter to lay their eggs and then swim back, leaving the eggs to develop on their own. In order to lay their eggs, female steelhead trout need a stream riffle with a gravel bottom. The eggs then hatch, and the newborn steelhead (alevin) soon develop into fry that consume zooplankton for subsistence.…
In the viewfind of my camera, I had at last framed the one thing that I most longed to photograph, a live, in captivity lemon shark. Tangerine looked at me with suspicious, yet curious eyes, no doubt wondering why I smelled of fish, as the water was tinted a slight red. Tangerine was a stunning, powerful creature, of 11 years old, about halfway through his lifespan. Since he was a lemon shark, he had a pale, yet vibrant shade of a soft mustard that had been mixed with a softer, sandy color, which is what it felt like to roll my hand on the left side as he circled me for the fish I had in my pocket, his flesh was squishy like slime, but also had a sandy feeling to it. Lemon sharks in captivity have a lesser brightness to the shade of yellow…
In our study, we had two controls that we placed the Lumbriculus variegatus into. First, we used spring water to get the normal heart rate of the worms. The other control was a caffeine solution that served as our positive control. Our other solutions that we exposed the worms to consisted of increasing concentrations of two different NSAIDs (ibuprofen and aspirin). For each NSAID, we had a solution equivalent to the recommended dosage for a person based on body weight (the proportional dosage solution), ten times the concentration of this initial solution based on the body weight of the worm, and one-hundred times the concentration of the solution based on the average weight of Lumbriculus variegatus.…

Most animals exhibit some type of aggressive behavior when confronted with one another, and this behavior is also shown in freshwater crayfish. Aggressive behavior in crayfish can be seen by anybody, but it becomes more prominent in a restricted laboratory setting. Groups of crayfish of about the same length and the same sex, plainly exhibit a pattern of dominance. When observed, it is noted that the crayfish perform different degrees of combative behavior. Researchers beg the question, how does the sex and the of size crayfish influence the different levels of aggression?…

The three-spined stickleback fish is a well known fish to Alaskans it has two pointy spikes on its back and it is a yellowish brown color. It is located in the Pacific Ocean and some salt water lakes near Alaska. The first recorded spotting of the stickleback was in 1964. The rates of fish being caught near Alaska have been recorded for many years and the rate of stickleback caught in the 1990's is double what is being caught now. Mating occurs in early spring and summer for these fish and it starts with the male building a hollow nest with seaweeds or aquatic plants.…
Catfish and largemouth bass are extremely different species of aquatic fish, but their ultimate natural instinct is the same. They strive to survive and produce offspring to carry on the essence of life, as all species do. Catfish are a very docile creature by nature, and their habitat ranges from lakes and rivers to creeks and little streams. They do not always need a fresh and constant supply of flowing water, but it makes for a more productive lifestyle.…
Native species are species that have evolved to in a particular region over a long period of time, and have adapted to live in that region’s climate and habitat. These species live in this region with all the other species to form an ecosystem. Non native species on the other hand, are species that are introduced to an area they're not used to by humans, either by accident, or intentionally (getthegreen). Invasive species are a type of non native species, that are very likely to cause harm to the ecosystem (NOAA). They destroy the habitat of other species, and eventually kill plants, and/or other species.…

Heraclides Ponticus and Aristarchus of Samos: “We know that the Earth is (or is not) at rest because...” The two philosophers Heraclides Ponticus and Aristarchus of Samos lived back to back as Ponticus lived from 390 BC – 310 BC and Samos lived 310 BC – 230 BC. Samos was a radical believer in the heliocentric theory of the universe, while Ponticus believed in the geocentric model; however, he believed that the Earth rotated on its axis, but it is at rest otherwise. Should these men have ever met and spoke proper English, then they would have a very stimulating debate over their views of planetary motion.…
