Adaptation Help living organisms to survive and reproduce in the ecosystem. Types of adaptations: 1. Structural adaptation. 2. Behavioral adaptation. 1. Structural adaptation: It is a change in the structure of the animal's body to adapt. 2. Behavioral adaptation: It is a change in the behaviors or acts of animals to adapt. Notes: 1. Camouflage: It is when animals hide from their predators or, their preys by blending in with the environments. 2. Migration: Is a behavioral adaptation. Is travelling of animals to long distances at certain time of the year.  Animal Habitat Structural adaptation 1- Polar bear Arctic 1- Thick fur to stay warm. region 2- White fur to camouflage for hunting. 2- Brown & Forest Dark fur to camouflage Black bear for hunting. 3- Caracal Desert Tan - Sandy fur to camouflage in desert. 4- Penguin Antarctica 1. Its body has a thick layer of fat and feathers to stay warm. (Except feet toes) 2. Feet toes are warm by the movement of blood vessels How do penguins’ feet get warm? 1- Blood vessels bring cold blood from the feet up. 2- Other blood vessels bring warm blood from the body down. 3- The warm blood vessels meet the cold blood vessels. 4- When they meet, the warm blood vessels heat the cold blood vessels. 5- So, the heat transfers to penguin’s feet. Warm blood from the body Cold blood from the feet  1- Fennec fox Habitat Hot deserts Structural adaptation 1. Tan - Sandy fur to camouflage. 2. It has large ears to cool its body. 3. It has a special shape of ears for excellent hearing to hunt. Behavioral adaptation 1. It pants like dogs to cool its body. 2. It lives in burrows to stay cool. 3. It eats different kinds of food, like insects, fruit, plant roots and leftovers of other animals.  2- Arctic fox Habitat Tundra Structural adaptation 1. It has thick fur to stay warm. 2. Its fur is white during winter, but brown in summer to camouflage. 3. It has short ears and legs to stay warm. 4. It has a special shape of ears for excellent hearing to hunt. Behavioral adaptation 1. It lives in burrows to stay cool. 2. It eats different kinds of food, like insects, fruit, plant roots and leftovers of other animals.  3- Panther Chameleon Habitat Tropical rainforest Structural adaptation 1.It has colored scales to camouflage. 2. Its eyes move in opposite directions, independently, so One eye search for food while the other eye is looking out for danger. 3. It has a long sticky tongue to hunt. 4. It has V-shaped feet and a tail like a hand to hold on tree branches. Behavioral adaptation Scare its attacker, where it appears as fierce, as the following: 1- It puffs up its body with air. 2- It opens its mouth wide. 3- It changes the colors of its scales.  4- Bull Shark Habitat Fresh and Salt water. Structural adaptation 1. It has a dark back and white belly to hunt. 2. It has sharp teeth to tear the prey flesh. Behavioral adaptation 1. It can hunt in both salt water or fresh water, and feed on different types of food. 2. It hunts in the day and the night, so its prey cannot predict when this shark will hunt next time. How can sharks hunt? By "Countershading". 1. When an animal swims above the bull shark and looks down into the ocean, it can’t see the shark due to its dark back. 2. When an animal swims under the bull shark and looks up, it can’t see the shark due to bright light of sun due to its white belly. Notes: 1. Bull sharks are the only sharks that live in fresh water. 2. Lizards are reptiles.
