Brown Shrimp Essay

Sharks can be divided into two main groups, large and small. The large sharks hunt for food so they are fast and agile. The small sharks usually hide in the ocean floor to catch prey and hide from predators. The gray and white, brown or blue-gray are mostly the fast and large sharks. The patterned sharks are the small slow sharks.

Especially for evasion or retreat, cephalopods use a particular type of locomotion through jet propulsion done through filling animal’s mantle cavity with water before pressing the water out of the cavity's opening with high speed. In general, cephalopods are the most active of the molluscs in their swimming speed. Self-defense: Cephalopods possess effective mechanisms which they might use for self-defense. For example, the ink similar substance produced from a gland in squids is used to confuse the attacker and even hampers its olfactory organs, so it cannot smell the squid. Some octopuses also use ink to confuse a prey (especially big ones, like lobsters) before attacking it from behind.

Body shape Description and the body shape of fish larvae are very useful for identification (Leis and Ewart, 2000). The general shape of body that contains the body depth (BD) to body length (BL) is classified as follows: Very elongated BD < 10% BL Elongated BD 10-20% BL Moderate BD 20-40% BL Deep BD 40-70% BL Very deep BD > 70% BL The data to body shape are relative to the size which during the development body size may become smaller. Some structures become smaller during in the process growing to another stage. 2.2.3.

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.

They have well-developed and symmetrical gills over which drawn water flows. The flow of water carries the waste and reproductive products. Movement: Although abalones occur in the same place, they may use their muscular foot with its suction power to move, cling and stay tight with the substrate surfaces. Feeding habits: In nature, abalone eats marine algae with a particular preference to large brown algae such as giant kelp and other kelp species. While juvenile abalone grazes for algae, diatoms and bacterial films, adults rely on drift algae, and if food becomes scares, they move after their food.

Common goldfish can grow up to approximately 12 inches in length which is larger than some of the containers the juveniles are kept in. They also produce a good deal of waste as they grow. Fancy varieties usually stay smaller than common goldfish, but their fancy fins are inclined to develop finrot in dirty water. This makes the lack of a filter problematic.

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.

Manoeuvering between them are fish of different sizes. Some look big enough to feast on the rest. Each speci has it 's own unique body designs that distinguishes them from each other. I see every colour on the colour spectrum but the most dominant being aqua, ultramarine, turquoise, indigo and emerald. A few highlights of magenta and scarlet left me marvelling for longer than anticipated.

The frog breathes through its skin and also has small lungs so the frog can breathe in water and on land. This helps the frog catch prey easier to survive. Based on the evidence collected during the dissection the worms food enters the mouth and goes through the pharynx where mucus is

The way that the medusa swims depends on the amount of prey around its environment which is why experts define them as a cruising predator. Its swimming patter is directional and at times the C. quinquecirrha may swim against the current making the C. quinquecirrha form into colonies. Additionally, a unique behavior of the C. quinquecirrha is that its swimming bells pulsates which helps provide the C. quinquecirrha with a supply of oxygen and it is a behavior that is inhibited by the
