Rene Ismail McKenna - C 9th Grade Biology PBA American Lobster - Homarus americanus Ecosystem/Ecology of Homarus americanus Adult American lobsters tend to dwell in depths of below 50 meters. However, some can live at depths of about 750 meters. They can weigh up to 44 pounds and reach a length of about 25 inches, however they are typically around 2 feet long and weigh 3 pounds. The American lobster’s preferable habitat is on rocky surfaces covered with algae, because algae attract animals that the lobsters prey on. This habitat allows the lobster to hide within the cracks, where it can hide from predators in its environment such as flounder, cod, crabs and eels.
Leather Back Turtle and its correlation with Human’s Food and Water Resourcing Activities. Species Description Weight: Adult: up to 2,000 pounds (900 kg) Hatchling: 1.5-2 ounces (40-50 g) Length: Adult: 6.5 feet (2 m) Hatchling: 2-3 inches (50-75 cm) Appearance: primarily black shell with pinkish-white coloring on their belly Lifespan: unknown Diet: soft-bodied animals, such as jellyfish and scalps, and pyro0somes Behavior: females lay clutches of approximately 100 eggs several times during a nesting season, typically at 8-12 day intervals. Life Cycle Juvenile leatherbacks may remain in tropical waters warmer than 26°C, near the coast, until they exceed 100cm in curved carapace length. Adults are pelagic and live in the open ocean, sometimes
Fleas and Ticks Cat Flea - Centocephalides felis Appearance Cat fleas are reddish-brown in color, and are about 1/6 inch in length or a little smaller than a sunflower seed. In the larval stage they are only 1/16 inch long worm-like and white. Behavior Fleas are ectoparasites and feed on the blood of birds, mammals, and reptiles. They have a relatively short life cycle and can rapidly reproduce. Once they have attached to a host they will begin feeding.
We went in to grab what we had thought to be any ordinary shell but had found it moving. After further inspection, we saw the green squishy flesh desperately trying to break out of its crusty encasing, no rupture in the shell indicated that the unfortunate cicada had much more pushing to go to escape its personal prison. My brother lifted the creature and attached its claws onto his brown dinosaur shirt and let the cicada hang, after playing with the bug for 5 or so minutes on his shirt he had become uninterested, which seemed to be happening increasing. He then placed the cicada back on the maple and
Besides these, when living in swamps or rivers, they will be also co-existing with shrimps and fishes. They are rarely alone, as they move in large groups, especially when laying eggs. They are also used as food for indigenous people, so at certain times, the conch will be in abundance but then gradually drop as they are caught and eaten. The average life span for Pomacea urceus is 2-4 years, with some living longer (Holswade 2013). Behavior: Pomacea urcues is an amphibious.
“Everyone knows what a lobster is. As usual though there’s much more to know than most of us care about – it’s all a matter of what your interests are” (Wallace 460). Novelist and essayist David Foster Wallace was the Roy E. Disney Professor of Creative Writing at Pomona College until he died in 2008. Wallace is best known for writing dazzling journalistic pieces, short stories and novels. In his 2005 article “Consider the Lobster and Other Essays”, Wallace brings it to the attention of people that lobsters are the one creature that are usually cooked while still alive.
Brine Shrimps tend to hatch in specific environmental conditions, such as high and low salt concentrations in water, weather and temperature. As one of the environmental conditions in which Brine Shrimp eggs hatch is water salinity and so, in this assignment, we were given 4 different salinity levels of water, which were 0%, 3%, 6% and 9%. As a result of the experiment, we noted that after 24 hours only one egg hatched at 3% salinity level and none at 0%, 6% and 9% levels. The second day, which was after 48 hours, there were 0 shrimps that hatched in 0% and 9% salinity levels, whereas at 3%, 7 out of 46(15.3%) eggs hatched and 6 out of 49(11%) at 6% levels. Based on this data our group concluded that the best level for hatching shrimps is 3%
They are in close linkage with trilobites and arachnids which are spiders and scorpions. Amazingly, they are not closely related to the "real" crabs which are crustaceans. Four extant species of horseshoe crabs are found and have survived over the geological period. They are classified to three genera in two families under the Superfamily Limulacea. They have nearly not been changed or evolved in millions years.
Also, they must be supplied with fresh water twice, which the guinea pigs may refuse to drink because of the taste. They should be fed commercial pellets daily because Vitamin C has been added to these pellets. Young guinea pigs can be given alfalfa-based pellets and adults can be given Timothy hay-based pellets. Refrain from giving pellets that have nuts, seeds, dried fruits, corn and animal by-products, beet pulp or other fillers. The same is true for pellets with high sugar content or with preservatives or other chemicals
