Effect of temperature Results In this experiment, results from two Procambarus propinquus (crayfish) were collected to observe the difference in oxygen consumption at different acclimated temperatures. These cray fish were collected from Medway Creek in London, and acclimated to their new environment and temperatures. The crayfish were exposed to the cold environment having an average temperature of 7° or warm having an average of 22°. An unpaired, two-tailed t test was performed to determine if there would be a change in O2 consumption between 2 individual crayfish.…
This species was introduced into the UK in the 1970s as food source. It spread quickly up and downstream and human introduction, although illegal, is still continuing. It may travel over land to colonise near freshwater. Its negative impact is mainly due to the loss of the native crayfish species, the white-clawed crayfish (Austropotamobius pallipes) through spread of disease and direct competition. Furthermore, the Signal crayfish is also impacting the river banks as it uses to burrow into them, creating instability of the vegetation and the ground.…
In 1969 two brothers were fishing on the Altamaha River at Clark’s Bluff, they reported seeing an animal that they first thought was a sturgeon. They changed their minds after looking at it for awhile and said it was 10-12 feet long, with a gator snout, and a horizontal tail. They also said the creature had a horizontal ridge on it’s back and it’s skin was grayish in…
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 invasive effects of Dreissena polymorpha on native mussels within the Great Lakes region The Great Lakes area once supported an abundant number of freshwater mussels (Mollusca: Unionacea). The invasion of Zebra mussels (Dreissena polymorpha) has decimated these populations, by outcompeting native mussels in dispersal rates, and reproduction, due to enhanced survival mechanisms. Understanding the mechanisms that have allowed Zebra mussels to out complete native fresh water mussels, will provide insight into possible mechanisms that can stop the spread of Zebra mussels, and help with the survival of native mussels. Griffiths et al. conducted length-frequency analysis of the Zebra mussel population, before 1988 (prediscovery) and between…
Using observationational skills, the organisms were located and collected using a dip net. All of the specimens live in salt water habitats, with crab being found both on land and in the water. Starfish are bottom dewellers and found ether on top of, or slightly buried under the sand. They can be located by shuffling feet through the sand. Sea sponges adhere to the coral reefs, other rocky areas and the soft mud of shallower areas.…
It is originally from india and has variations of the snakehead. The fish has no natural predator…
Experiments were set up using the species Procambarus alleni Faxon. The crayfish were taken from their native ponds and swamps in Florida to a laboratory setting. In groups…
Their bright red caudal fin (tail) completes their visual appearance and name. As with any member of the carp family they are primarily bottom dwelling scavenger fish. Scavenger fish can be identified by their downward pointed mouths with varying sets of barbels on either side. Barbels are whisker-like sensory organs that contain taste buds much like your tongue.…
Manatees are marine mammals that need warm water in the colder months of the year to survive; which makes Florida a prime location. (Blitz, 2016). In the past, manatees depended exclusively on warm water springs as well as other sanctuary areas previously during the winter months, but with the discovering of power plants a large number of manatees started utilizing these release basins as sources of warm water for refuge. These power plants use bay water as coolant. Once released back into the bay, the water is unchanged except for a slightly higher temperature.…
The Red Tide Kyle X. Singleton 10/11/2015 GEOS101 Jennifer Lundberg From being a small child in Chicago, to now being an adult, I have traveled to quite a few different places and now even live on a different coast. During these travels, I’ve seen a number of different waters in the places I’ve lived and even more with me being in the Navy. I honestly thought that Lake Michigan was pretty clean growing up with the exception of the seaweed and litter floating around. While at summer camp one year, I traveled to Green Lake WI, and was so amazed that the water was actually green. On a side note, I remember that WI water always smelled like eggs.…
The mantis shrimp is one of the deadliest crustations on the planet. the two most common kinds of mantis shrimp are the smashers and the spearers the spearers have claws that hence the name are covered in spiky teeth that they use to impale her future food. the spearers usually feed on soft skinned fish for such as fish, shrimp and…
The African crake (Crex egregia) is a bird in the rail family that breeds in most of sub-Saharan Africa, except for the arid south and southwest. A partial migrant, it moves away from the equator as soon as the rains provide sufficient grassland or crops for breeding areas. It is commonly found in most of its range, depending on the season. A smallish crake, it has brown-streaked blackish upperparts, bluish-grey underparts and black-and-white barring on the flanks and belly, with a red bill, red eyes, and white facial…

At first glance you might think they are from out of this galaxy, you might think they are gross,stenchy ,or even rodent like, but in the end they will smell and taste like a dish from the last supper. Deep in the scorching southern states of America you can find them in every muddy, muggy swamp. I’m not talking about alligators or even turtles, that’s right I’m talking about the little red creature called a crawfish. Or better yet in the backwoods referred to as the “mudbug.” If you ask any fishermen what a mudbug is they’ll tell you “it is a dang good fishing lure.”…
