Being able to raise and observe different species of marine life in a tank is good to protect a variety of marine species. One can observe how they act toward each other and many other interesting behaviors. This paper will be describing three topics, Beginning with Saltwater fish, The Arc - eye Hawkfish (parachirrhites arcatus) and Filefish. Eye Hawkfish and Filefish are two types of marine fish. There are certain things to consider when keeping fish in salt water tanks, to understand and start with the basics, here is what needs to be done first to have a saltwater aquarium. The basics are actually quite basic!
If a lake is cut from the ocean and has no large fish as predators (only dragonflies), then the sticklebacks will have a better chance at surviving and reproducing because the sticklebacks will be better adapted to the environment (presence/absence of a pelvic bone) and have little to no predators. The hypothesis was supported. Before the experiment started, background knowledge was collected to better the knowledge of the lakes. Bear Paw Lake is an enclosed lake, meaning no predators could get into the lake.
Introduction: Daphina are planktonic crustaceans that belong to the class Phyllopoda(Branchiopoda) to which flattened leaf-legs used in producing a water vcurrent for their filtering apparatus. In the brachiopods, Daphnia belong to the order Cladocera whose bodies are encloosed by carapace, which is made up of chitin and polysaccharide. The carpace forms double wall separates hemolymph anda part of body cavity. Animals which belong to the order Cladocera, have up to 10 pairs of appendages, which include antennules, antennae maxillae, madibles, five or six limbs, which also form an apparatus for both feeding and respiration(this apparatus is used to filter food particles even bacteria. So, they are filter feeders) and a pair of claws.
Daphnia are very abundant organisms in freshwater lakes. They tend to live in the upper algae rich portion of the water, feeding on phytoplankton, bacteria and decaying organic matter. Daphnia and bosmina both serve an essential role in he food chain in most lakes, serving as a resource for numerous predators. Trout tend to feed on small crustaceans like daphnia and dosmina. Trout are visual predators and therefore feed on the larger daphnia thus providing bosmina a competitive
We took a large net and set it vertically in the water, and then somebody got in the creek and kicked up sediment into the net. After doing this a few times, we collected all of the creatures off of the net and into an ice cube tray. We then examined the creatures and noted the variety (or lack thereof) of the creatures. The larger the variety in the species of the creek, the healthier the creek is. We noticed several species of fly larvae such as stone fly larvae and caddis fly larvae. We also noted a few worms.
For example, in southwestern Arizona, T. o. luteola is commonly active during the summer monsoon (July through September) when humidity levels are relatively high as compared with other times of the year (Ornate box turtle, n.d.; Ernst & Lovich, 2009). While the eyes of the female desert box turtle have a yellowish to brown iris, the iris of the male is red, and the male’s tail is longer and thicker than that of the
In addition to birds, plenty of fish can be found in the basin and fishermen frequent the basin in search of Tilapia (3). Tilapia can be found by the hundreds in the basin along with corvina and an occasional striped bass, mullet, croaker, or sargo (3). The endangered pupfish, though rare, also rely on the basin for survival (10). Pupfish are also the only native species in the Salton Sea, thriving in shallow bodies of water with a high salt and heat
Biotic components of ecosystems include plants, animals, and fungi living in that ecosystem that interact with the environment and other abiotic and biotic components. 8. Create a chart of the major characteristics of and differences between the following terrestrial biomes: Tundra, taiga, grasslands, temperate deciduous forest, desert, monsoon rainforest, tropical rainforest. 9. Create a chart of the major characteristics of and differences between the following aquatic biomes: freshwater ecosystems such as lakes, wetlands, and streams, marine biomes such as estuaries, intertidal zone, neritic zone, open sea zone, and deep sea zone.
In this research paper we will explore more about coral reefs and their importance. Coral reefs are communities of living organisms. They are made up of fishes, plants, and many other creatures. They have been around for millions of years: less than the 0.1% of the world’s ocean floor Is covered by coral reefs, however they grow very slowly, from 0.3 cm to 10 cm per year.
Coral reefs are the most diverse communities in the marine environment. Hermatypic-corals help form the structure of coral reefs and a shelter for a variety of organisms. Living coral reefs form land, provide the sand that lines tropical beaches, and the structures which prevent the waves from causing extensive coastal erosion. However, pollution from sewage and agricultural practices damages corals as well as the wide variety of organisms living within them.
