Water quality is a term used to describe the chemical, physical, and biological characteristics of water, usually in respect to its suitability for a particular purpose. The Jordan River has other rivers flowing into it so it has multiple different sources of water. The physical predictors such as habitat type, channel type, temperature, and flow rate can assess the quality. Chemical predictors such as pH, dissolved oxygen, and turbidity can also assess the quality of a stream. Thirdly, the…

how they relate to their environment or ecosystem. What is a mealworm? A mealworm is a dark beetle larva. Mealworms have a head, thorax, and an abdomen. The mealworm has a spine but not the kind that we have. The mealworm is part of the invertebrate. The invertebrate family is a group of species that don’t exactly have a spine. The mealworm start off as an egg, then once they hatch, they turn into a larva. This is the stage that they look like worms. After living like a larva, they turn into a…

shark. The sharks are the only ones that are on top of the food chain; they are the main predator. They mostly feed on fish, eels, and crabs, and can survive six weeks without food. Echinoderms are invertebrates (animals without a backbone), usually with five appendages (a projecting part of an invertebrate), that come out of their bodies. Echinoderms are very common in coral reefs and there are more than 1200 species of sea…

All organisms, vertebrates and invertebrates, must have necessary nutrients to maintain life. In invertebrates, either a transport system or diffusion provides nutrients to the body. For vertebrates, a closed transport is used to transport blood away from the heart. Both of these scenarios are key to an organism 's health. Some invertebrates do not require a circulatory system. While these organisms do not require a circulatory system, they require certain nutrients to be readily available.…

creatures are amazing and delightful. Some spotted jellyfish that are large have small fishes living with them. Narwhals have a tusk that is actually a tooth that can grow to 10 feet long, but not all narwhals have tusks. Octopi are the smartest invertebrates. Octopi are able to open a container with prey in it. My favorite underwater creatures are narwhals, spotted jellyfish, and octopi. One of my favorite underwater creatures are narwhals. Narwhals live in the Arctic waters of Greenland,…

Kingdom: Animalia Phylum: Porifera Classification information for Poriferans: Poriferans, better known as sponges, consist of 5000 known species, all located primarily in marine and fresh waters (Myers, 2001a). They are multicellular, heterotrophic, invertebrates with an irregular shape and no distinct pattern of symmetry (Myers, 2001a). Overall, they are the simplest of animals; thus, lacking any true tissue and/or germ layers (Myers, 2001a). Furthermore, they are known to be highly sessile,…

slow, are a step in the right direction toward ethical treatment of all creatures. Dr. John Cooper, of the European College of Veterinary Pathologists, has been making advancements in anesthesia, analgesia, and euthanasia of invertebrates. He believes that the care of invertebrates and the care of vertebrates should be equal and that the care shown should be reflected in the research conducted. Dr. Cooper along with countless others are finding new and innovative methods to lessen and reduce…

The Eurasian curlew and the Peregrine falcon are two different bird’s species with noticeable anatomical and behavioral differences between them. While the curlew feeds from invertebrates, at the same time it becomes the prey for the falcon, which is conditioned by another feature of their anatomy, their beaks. A decurved bill such as the one present in Numenius arquata has numerous advantages over a straight bill for such foraging on mudflats. Foraging Curlews use probing as a way to take…

Discussion: The techniques used in this experiment are very useful for an efficient assessment of the quality of the habitat with regards to scavenging. This experiment is not costly with experimental apparatus and design. The high cost of achieving these consistent results is effort and time. The experimental set up required many participants to carry out the procedure however since each area was only studied for 40 min this is a relatively rapid assessment. The most dominant ant scavenger…

(Kuroda, 2012). It affects mammals just like it affected bees. The nicotine found in the neonicotinoid have these negative effects. The nicotine effects the function of the brain and nervous system in humans like it does with the bees and aquatic invertebrates (Kuroda,…
