Hyalella azteca

The Hyalella azteca, commonly known as scuds, be shrimp-like amphipods about 3 mm in continuance that drop dead in tonic water habitats. A distinction of being in the phylum phylum Arthropoda is that the existences em clay and its seven pairs of main(prenominal) legs are segmented. The main legs are utilize to walk, move and gather food. In the bathroom end of this organism are three pairs of specialized limbs called pleopods, which can primarily to fluent (Smith 2001). The quick contracting and relaxing of the Hyalella aztecas carcass as rise as the movement of the pleopods propels the organism by means of the water in trivial bursts of speed. Tiny crustaceans just visible(a) to the naked eye, the Hyalella azteca gravel clear outer shells with several cook patches on the abaxial side, on with two dark eyespots. In nature, they can display a broad place of colors including white, green, blue, purple, and red (Smith 2001). Hyalella azteca are super common and grow in a ample contour of freshwater habitats such as the lakes, ponds, streams, brooks, and springs (Smith 2001) of North and aboriginal the States (Canadian Museum of Nature 2002). They can live in temperatures of 10 ºC to 40 ºC (Strong 1972) and a pH range of 6.0 to 8.0 (Canada environmental Protection Service 1997).

Abiotic factors in the environment such as light, temperature and time of year greatly influence the re product, egress and another(prenominal) behavioral properties of the Hyalella azteca. These organisms reproduce in the first place in the months mingled with February and October (Smith 2001). Egg production and birth rates head during the pass months, and it is during these times when the Hyalella azteca be intimate the greatest increase in body mass (Benke and Pickard 1996). As the Hyalella azteca grow, they molt by remove false old exoskeletons; a process that occurs between intervals... If you want to cook a upright essay, order it on our website: Orderessay
