Adaptation of Animal

1. Adaptation of Animal WILD ANIMAL DOMESTIC ANIMAL

2. 0 Introduction: Clown, Fool, or Simply Well Adapted? Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. • What is an adaptation? • Behavioral adaptations • Structural adaptations • Biochemical adaptations • Physiological adaptations Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Biochemical Adaptation is an encouraging demonstration that we are on track to bridge the gap between genotype and phenotype A metabolic or physiologic adjustment within the cell, or tissues, of an organism in response to an environmental stimulus resulting in the improved ability of that organism to cope with its changing environment.

3. Wild animal vs Domestic animal The wild animals is an animal that lives in a basically natural undomesticated state. Wild animals provide for their own essential needs such as food, water, shelter and they find and select their own mates. Therefore, wild animals are usually well adapted for the habitat(s) in which they are living. Domesticated animals, frequently do not find or choose their own mates instead they are bred for specific uses by humans. Consequently, they frequently are not adapted for the environment in which they live but are trained or adapted to live in a human environment and provide products or services to humans.

4. WILD ANIMAL CANDIRU FISH

5. Description Name : Candirú or caneroVandelliscirrhosa Appearance : They can reach lengths of 1-2.5 in (2.5-6 cm) with a width of 3.5 mm ,shaped like an eel and transparent so hard to see in the water. Candiru is a tiny parasitic catfish that inhabits the waters of South America The candiru has sharp bones with a series of spines located around the head used while feeding.

6. HABITAT The candiru is found only in the Amazon and Oranoco Rivers of South America. They do not like the sun and tend to burry themselves in the mud and sand of the river bottom underneath logs and rocks.

7. The parasites can live on the gills of other fish and even in humans. They can live in the human intestine, stomach, and even crawl up the urethra, vagina, and/or anus Image Ray Fish Candiru enter the human body through the penis hole Fish candiru entry into the eye. These fish are able to enter through any small crack.

8. To find fish Taste The water trying to locate a water stream that is coming from the gills of a fish Once such a stream is detected, the candiru follows the stream to its new host and inserts itself inside the gill flap Spines around its head then pierce the scales of the fish and draws blood while anchoring the candiru in place The candiru then feeds on the blood by using its mouth as a slurping apparatus and while rasping the long teeth on its top jaw.
