These creatures live in coral reefs for many reasons as I said before, for housing, for finding food and even for hiding from their predators. There are all types of different creatures with shining colors and surprising shapes. As I said before, millions of species live in and around coral reefs, for example sponges have been part of this ecosystem from early on. They provide shelter for many other creatures such as fishes, crabs, and many more small animals. They have also a very big variety of shapes sizes, and colors.
The largemouth bass have the ability to hide from their prey and provide protection against their predators through the process of abundant vegetation. Their surroundings is usually made up of clears waters so that they can use their vision to identify their prey. The range size in most environments is usually no greater than three meters. (Hannon, 1996; Iguchi and Matsuura, 2004) The largemouth bass is dioeciously, meaning they have separate sexes in reproduction, male and female. The largemouth bass reproduces in the spring.
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.
A well known example of this is the infamous anglerfish (Lophiiformes). Anglerfish posess a modified dorsal fin, the illiceum, at the tip of which is a bulb, the esca, which contains symbiotic luminescent bacteria. This esca is used both as a light to guide the fish, but also to lure prey to the anglerfish’s mouth. (Munk, 1998). The Cookiecutter shark’s bioluminescent cells imitate the faint light of the surface above, camouflaging it when viewed from below and so allowing it to approach its prey without being seen.
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.
However, female will need some hiding places where they can hide as they cannot get way from the male in an aquarium. A sandy substrate can be used to mimic the natural conditions of the lake. Cichlids from this environment include: Cyprichromis leptosoma, C. microlepidotus, C. pavo, C. sp. leptosoma jumbo and C. sp. “Zebra”.
Even consumers are now more aware, the use of nudge theory along with consumers has made them far more interested in local products than imports from blockading countries. This can be shown positively in the current account in the future and insures food security in the long-term. • Second point As the economic blockade was imposed, it caused short-term worries and tensions to arise in the economy. It has resulted into the expats sending their savings abroad. transfer of large amounts of money that wealthy individulas into their overseas banks.
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.
Have you ever thought what would we be like without fish. How important is our marine life? Over fishing is a huge problem that needs to be brought to an end very quickly. Overfishing is an urgent matter that should not be pushed aside as if it was not as important as the rest. As a result of overfishing, we could lose 90% of ocean fish.
Overfishing, by definition, is fishing until fish stocks are at unacceptable levels in any body of water, particularly the ocean. Overfishing creates a complex, interconnected web of problems which is difficult to untangle. For starters, it depletes fish populations ruthlessly. As a
Starting with the food chain in Chesapeake bay, the plants and algae play the basis role in food chain. They make their own food by sunlight. These plants and algae are bay grass and free floating algae. The plants and algae not only feeds all other organisms in the water but also gives homes and shelter for other organisms. Frogs lay their eggs on the bay grass, giving the tadpoles a home.
When nests are found, the biologists enter information on field cards about the number of eggs, species, whether eggs are broken, temperature of the nest and whether the eggs are polarized. If the eggs have progressed to where a shell forms, the yolk has polarized and begun developing into a baby turtle. These eggs are left in the nest, which the team monitors, patrols and tries to protect. The biologists also mark the nests from which the eggs have been removed so that other researchers from the sea turtle protection program know that the nest has already been
Lionfish were most likely introduced through the pet trade like the python. Although there is another theory that they were introduced by floating lionfish nest, it is rather unlikely considering that the nearest native range for them is the South pacific and the Indian Ocean around Australia and India. Lionfish were first reported off of Florida 's Atlantic Coast near Dania Beach in 1985. The lionfish 's habitat ranges greatly from 1 foot of water to 300 feet. It usually thrives in reefs but it is also easily found in hard bottom areas, mangroves, seagrass flats, and shipwrecks.
These banks contain coral rubble, seagrass and macroalgae with other invertebrate taxa, which play a key part in the ecosystem. The bank systems contain essential fish habitats, which provide sheltering and foraging grounds. Past studies have indicated these fish assemblages showed a high diversity and biomass of coral reefs. Most of the biomass in the Florida Keys ecosystem is made up of species that stay in channels for most of the day. These signs show that the bank systems are important for the FKNMS for providing a structural support and high productivity for the biodiversity.
If the abundance of the kelp forest changes it will also affect the amount of fish. Overfishing has led to an increase in sea urchins, which led to a deterioration of kelp forests. Other aspects that affect the kelp forest are diseases, harvesting for kelp, and pollution. When the top of the food chain is removed such as a starfish, barnacles and snails begin to rise. A lot of these animals are herbivores, which also eat kelp.
