They accomplish this by feeding on algae and bacteria. 8 Species of mussels are native to the river. The most prevalent are the eastern elliptio mussel and the eastern lamp-mussel. Mussels are eaten by a variety of birds, turtles, fish, muskrats and other mammals. Zebra Mussels are an invasive species that can cause harm to native species by attaching themselves to their shells preventing free movement and can even cut off their oxygen
Some are unicellular and some are multi cellular. Bacteria is a large group of single celled organisms that are found in every corner of the earth, be it land, air or water. Viruses are parasites which means they can cause harmful diseases such as small pox. (www.sciencedaily.com/articles/m/microorganism.htm) Algae are another diverse group of plants that may be unicellular or multi-cellular but are autotrophic. Diatoms are type of algae , found in toothpaste, they can be classified into two groups called centric and pennate.
It feeds on ectoparasites or dead tissue that it picks from the body and oral cavities/gills of these fish (e.g. ; Tangs or Groupers) in the wild or in the aquarium. This also helps to protect the fish from contracting diseases and infections. Many fish value its services so highly that they will allow it to clean the inside of their mouths, and not harm it. Some fish, though, such as Hawkfish, Lionfish, and some predatory shrimp and crabs may eat the Scarlet Skunk Cleaner Shrimp.
Younger lionfish have a unique tentacle above their eye sockets, which differs in appearance between species, but studies show that this tentacle has evolved over time in each species serving to attract new prey. Juvenile lionfish eat mostly invertebrates, but shift their diet to fish as adults and eat reef fish. Adult lionfish spread their pectoral fins and use them to "herd" prey. This is a very effective predatory style because it is unfamiliar to native Florida fish. However, Lionfish can have negative effects on the overall reef habitat as they can eliminate organisms which serve important ecological roles such as herbivorous fish which keep algae in-check on the reefs.
“Frankenfish” entire diet mostly contains other fish, as well as plants and insects. Every now and then, they also enjoy human flesh. (Urbanlegends.about.com). Parent Snakeheads are known to over protect their young. In one instance, the parent attacked a human who approached their babies.
Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas. Daphnia live in various aquatic environments ranging from acidic swamps to fresh water lakes, ponds, streams and rivers. The heart is at the top of the back, just behind the head, and the average heart rate is approximately 180 bpm under normal conditions. Daphnia, like many animals, are prone to alcohol intoxication, and make excellent subjects for studying the effects of the depressant on the nervous system due to the translucent
Plants, animals, humans, fish, birds and reptiles can all be host to parasites. Head lice, thread and other worms are all parasites; they survive by feeding on the blood of their host. Some bacteria and viruses could be considered parasites. 1:2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Bacterial Infections: Salmonellas/ food poisoning, tuberculosis/TB, MRSA, coccidiosis, food poisoning, dysentery, bronchitis, ear infections, tonsillitis. Viral
Their narrow pointed teeth are ideal for holding prey, most of which is swallowed whole. Tests on the feeding habits of angel sharks have shown that they react to any passing prey, spitting out anything that does not appeal to their appetite. They have complete faith in their camouflage when approached by divers but will inflict a shallow bite if harassed. The various species of Angel sharks range in size up to 6.5 feet (2 m) long and are mostly bottom dwellers that live on ocean floors of depths from 10 to 4,300 feet (3 to 1300 m). They sometimes prefer however, sandy near shore habitats.
How does the adrenaline affect on the heartbeat of daphnia? Adam Stępień IIB Background information: Daphnia- they are small, planktonic crustaceans, between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They live in various aquatic environments ranging from acidic swamps to freshwater lakes, ponds, streams and rivers. Epinephrine (adrenaline) - is a hormone and a neurotransmitter.
Parasites - A parasite is an organism that lives on or within another living organism, it feeds off of the host. It can be very detrimental to the host. 1.2 Identify common illnesses and infections caused by: Bacteria - Clostridium Difficile, (C-Diff) Diarrhoea. Legionella,through water contact, can be water coolers and showers heads Salmonella, is passed human to human through food or water MRSA – usually from urine tract and catheters Viruses - Hepatitus A,B and C. Transmitted through bodily fluids HIV. Transmitted through blood, sexual contact, Influenza.
