1. What are harmful animals?
Harmful animals do harm to humans by spreading disease, causing injury, destroying crops and goods, or otherwise causing unpleasant effects. An animal can be harmful in certain circumstances but not in others. For example bees produce tasty honey and pollinate plants but if they attack a human it hurts.
2. What is the difference between harmful animals and poisonous animals?
Some harmful animals are poisonous but not all poisonous animals are harmful.
An epidemic (from Greek ἐπί epi "upon or above" and δῆμος demos "people") is the rapid spread of infectious disease to a large number of persons in a given population within a short period of time, usually two weeks or less. An epidemic may be restricted to one location; however, if it spreads to other countries or continents and affects a substantial number of people, it may be termed a pandemic.
Zoonosis describes the process whereby an infectious disease is transmitted between species,usually to diseases that can travel from animals to humans. They include all diseases. Many serious epidemic diseases are zoonoses which originated in animals. These include rabies, Ebola virus disease and influenza. In a systematic review of 1,415 pathogens known to infect humans, 61% were zoonotic. The emergence of a pathogen into a new host species is called disease invasion or "disease emergence". The emerging interdisciplinary field of conservation medicine integrates human and veterinary medicine.
Zoonoses can be classified by infectious agent type:
- protozoa, helminths (nematodes, cestodes and trematodes)
4. Know at least 4 kinds of diseases transmitted by harmful animals.
- Rabies obtained from being bitten by an infected animal like a dog or bat
- Malaria (mosquito bite spread)
- Herpes B is commonly found in macaque monkeys, including rhesus, cynomolgus, pig-tailed, stump-tailed, and Japanese macaques. The B virus can be shed lifelong in their saliva and all adult macaques should be assumed to be carriers. The B virus can be transmitted to people through bites and scratches, and can cause acute neurological disease and fatal encephalitis.
- Cat scratch disease is a mild to severe bacterial disease caused by Bartonella henselae. Young cats and kittens are the most likely source of human infection. The infection is transmitted between cats by fleas. Infected flea droppings on the cat's fur are the source of human infections, which are spread from the cat to a person by a cat bite, scratch, or lick. Cats rarely show signs of illness but people can develop skin lesions, fever, or in severe cases, systemic (whole body) infection.
- E. coli infection from animal or human fecal matter
- Leptospirosis is a bacterial disease that infects both humans and a wide range of animals. It occurs worldwide but is more common in temperate and tropical areas of the world. Some people infected with leptospirosis will have no symptoms at all, and some people will become severely ill. Some wild and domestic animals, such as cattle, pigs, dogs, raccoons, and rodents, carry the bacteria and pass them in their urine. People become ill following direct contact with urine or tissues from infected animals, or exposure to contaminated soil, food, or water, including from swimming in contaminated water.
- Lyme disease, a bacterial disease, caused by Borrelia burgdorferi, is transmitted by the bites of infected ticks. Ticks become infected by feeding on infected rodents.
- Plague is a serious infection of humans caused by bacteria the bacteria, Yersinia pestis. The bacteria are present in wild rodents and their fleas.
- Rat Bite Fever is a bacterial disease that is spread to people through bites or scratches from rats. Symptoms include abrupt fever, vomiting, headache, muscle, back, and joint pain, and then a rash on the hands and feet and swollen joints.
- West Nile virus is spread by mosquitoes that pick up the virus after feeding on infected wild birds. People, horses, and certain types of birds are most often affected by this virus. Most people infected with the virus don't get sick, but some may have an illness ranging from mild to severe. In the severe forms, West Nile virus affects the nervous system and may result in meningitis, encephalitis, paralysis, or death.
5. How can animals harm plants and the lives of other animals?
Invasive species of dangerous animals can create problems for established species. The harmful animal may kill off other species directly by eating them, or indirectly by using up resources the established species needs to survive.
6. Choose and present the following characteristics of two harmful animals:
See examples in Requirement 7.
b. Type of sexual reproduction
c. Eating habits
d. Diseases and harm to humans
7. Name at least three harmful animals in the following classes:
|Rattus rattus (Black rat)|
Description: common long-tailed rodent of the genus Rattus (rats) in the subfamily Murinae (murine rodents). The species originated in tropical Asia and spread through the Near East in Roman times before reaching Europe by the 1st century and spreading with Europeans across the world. Black rats are generalist omnivores. They are serious pests in nature as they eat birds and insects, and to farmers as they eat a wide range of agricultural crops. They are vectors of many diseases including the bacterium Yersinia pestis, an agent of bubonic plague.
Habitat: everywhere they can get a foothold
|canis latrans (Coyote)|
Description: the coyote is a canid native to North America. It is a smaller, more basal animal than its close relative, the gray wolf, being roughly the North American equivalent to the old world golden jackal, though it is larger and more predatory in nature.
Habitat: widespread in North and Central America including rural and urban environments
|Pagophilus groenlandicus (harp seal)|
Description: The harp seal or saddleback seal is a species of earless seal native to the northernmost Atlantic Ocean and parts of the Arctic Ocean. The latin name means "ice-lover from Greenland"
Habitat: northernmost Atlantic Ocean and parts of the Arctic Ocean, often on ice flows
|Heloderma suspectum (Gila monster)|
Description: A heavy, slow-moving lizard, up to 60 cm (2.0 ft) long, the Gila monster is the only venomous lizard native to the United States and one of only two known species of venomous lizards in North America, the other being its close relative, the Mexican beaded lizard (H. horridum).
Habitat: Southwestern United States and northwestern Mexican state of Sonora.
|Crocodylus niloticus (Nile Crocodile)|
Description: An apex predator, the Nile crocodile is the second largest reptile in the world. On average the Nile crocodile is between 4.1 metres (13 ft) to 5 metres (16 ft), weighing around 410 kg (900 lb). However, specimens measuring 6.1 metres (20 ft) in length and weighing 907 kg (2,000 lb) have been recorded. They have thick scaly skin that is heavily armored.
Habitat: The Nile crocodile is quite widespread throughout Sub-Saharan Africa, occurring mostly in the central, eastern, and southern regions of the continent and lives in different types of aquatic environments such as lakes, rivers and marshlands.
|Oxyuranus scutellatus (Coastal taipan)|
Description: Coastal taipans are the largest venomous snake in Australia. Adult specimens of this species typically attains sexual maturity around 1.2 m (3.9 ft) in total length (body + tail). More mature specimens can grow to between 1.5 and 2.0 m (4.9 and 6.6 ft).
Habitat: Coastal taipans can be found in a variety of different habitats. They can be found in warm, wetter temperate to tropical coastal regions, in monsoon forests, wet and dry sclerophyll forests and woodlands, and in natural and artificial grassy areas, including grazing paddocks, and disused rubbish tips. The coastal taipan snake, despite its name, does live in habitats hundreds of kilometres away from the nearest beach. The can be found in northern and eastern Australia and the southern portion of the island of New Guinea.
|Rhinella marina (Cane toad or Marine toad)|
Description: A large, terrestrial true toad which is native to Central and South America, but has been introduced to various islands throughout Oceania and the Caribbean as well as northern Australia. Adults average 10–15 cm (3.9–5.9 in) in length; the largest recorded specimen weighed 2.65 kg (5.8 lb) with a length of 38 cm (15 in) from snout to vent. The species derives its common name from its use against the cane beetle (Dermolepida albohirtum).
Habitat: The cane toad inhabits open grassland and woodland, and has displayed a "distinct preference" for areas that have been modified by humans, such as gardens and drainage ditches. In their native habitats, the toads can be found in subtropical forests.
|Amietophrynus regularis (Egyptian toad or African common toad)|
Description: The most common frog or toad in Egypt, and across much of Africa. The African common toad is a large sturdy toad with a warty skin. Males grow to a snout-to-vent length of 62 to 91 mm (2.4 to 3.6 in) and females reach 70 to 130 mm (2.8 to 5.1 in). The paratoid glands are large and either parallel or kidney-shaped and the male has a single vocal sac under the chin. The dorsal surface is dark olive-brown with dark patches on the back, often arranged fairly symmetrically, and in younger animals, there is a paler band along the spine. There are smaller dark blotches on the upper lip and the eyelids, and the warts on the flanks are often separated by dark markings. The throats of males are black and the underparts of both sexes are white to beige. The call is a rattling sound made up of two pulses and lasting for about 0.9 second.
Habitat: both moist and dry savanna, montane grassland, forest margins, and agricultural habitats. It is often found near rivers, where it also breeds. It is not a forest species but in the forest zone it can still be found in degraded habitats and towns (including gardens).
