adaptations - are features organisms have to enable them to survive (and reproduce). behavioral adaptations - how they act in response to things (what does a cat do when threatened) structural adaptions - how their body parts function (what body parts can a cat use to fend off an enemy?) Some protective adaptations are locomotion - ability to move from place to place. mimicry - is the ability to appear to be or to imitate something other than what you really are warning coloration - color and patterns that make organisms more noticable or stand out to warn off others. camouflage - colors and/or patterns that blend in with its surroundings in order to become less noticeable or hide.
skunkSpray foul smelling scent. Sharp claws. Warning coloration (black with contrasting white stripes).Hisses, stamps feet, raises tail to threaten. mooseStay quiet and still. Males can fight with antlers?(Drop off in winter). Strong legs and sharp hooves to kick. Run fast. Keen sense of smell. Good hearing (ears swivel). Color may be camoflauge in woods. May charge and kick/trample enemy. opossumPlays dead. Grimaces. Clings to things. rabbitSeasonal color change for camoflage. rosebushThorns. catHisses, spits. Arches back, puffs up fur, sticks tail up to look bigger (more threatening). Sharp claws, teeth.
turtleMost can withdraw into shell. Sharp beak. Scales on legs. Hissing. Some squirt water, body wastes, emit foul smells. Snapping turtles lunge and bite. Some Bury eggs on beach. Hatchlings head immediately for sea. birch treeDrops leaves in winter to avoid snow loading and damage. Strong flexable wood/roots avoid wind damage. fir treeNeedle leaves are sharp. Cone shape of tree and needle leaves don't hold snow or catch much wind. seahorseLooks (color and shape) like seagrass beds on reefs. (camouflauge and mimicry?) vice-roy butterflyColor and wing pattern makes it look like toxic monarch butterfly (mimicry) so birds won't try to eat it.
fox Quiet and quick to catch prey. Sharp teeth (canines) are used for piercing and holding onto prey. Strong legs fast/quick for catching food. Camouflage coloration (arctic fox is white) for hiding from enemies or hunting prey. Arctic fox decreased basal metabolic adaptation to food scarcity in winter. moose Long legs which are suited for ploughing through deep snow, walking over bushes and logs, and wading through muskeg. Close off nostrils to feed underwater. Big muscular lips to pull up plants. Tilts head back to put antlers along back to aid in running through brush, trees. robinFinds worms by keen eyesight (not by hearing!), quick movemens to pounce on them and a beak to pull them up. Beak to crush seeds, small insects. Some store food for later. Some break food against ground, rocks. Parent regurgitates or bring food to young in nest. eagleKeen eyesight. High flight. Sharp claws (talons) and sharp hooked beak.
birch treeRoot system. Broad large leaves on high up branches to catch sunlight for photosynthesis. Vascular system to bring sap from root to leaf. pitcher plantLeaves form pitchers (water holding jugs) to drown and dissolve/digest insects for nutrients. Down pointing hairs inside to prevent insect escape. Color, smell to attract insects. (Grows in poor soils - simple roots!) spiderSpin sticky web catch insects. Venom (bites) to paralize. Venom preserves/digests inside of prey, spider drink it out. Wrap and store insect. Move quickly. bread moldFloats in air (as a spore) until it lands on food. Secrete digestive enzymes (fluids) to dissolve food then absorbs the nutrient products. Grows through the food.(Can't make their own food- not plants so don't need light!)
Create your own creature Design-a-Saurus Students create a drawing of a real or imagined prehistoric creature and name the creature after a place of discovery, an honored person, or an adaptation. 1. Review. Think of the different adaptations we have discussed or seen in the films. The three ways scientists name something that is living or was once alive—after a person, a place, or an adaptation. Paleontologists often draw animals that they study.
2. Start Activity. You are going to create a profile of a real or imagined prehistoric creature (land or marine). To complete the assignment, you should: Draw the real or imagined animal. Label three adaptations, noting how it helped the animal survive in its environment. Explain where it was found and who first discovered it. Name the prehistoric creature. If it is an imagined animal, create a name after an adaptation, a place, or a person. If it is a real animal, explain the origins of its name. Write paragraph about the animal, where it lived, how it survived, what adaptations allowed it to be successful or unsuccessful (physical and behavioral), when it became extinct.
Student Presentations: Share your work with the class. Introduce your animal by name, describe the animal (including its body parts – adaptations and behavioral adaptations) and how those adaptations helped it survive in its environment, and determine if the animal is named after a person, a place, or an adaptation.
Bird Feet Adaptations coot - lives in marshy areas foot padding serves to keep it from sinking into the soft ground. Claws for digging for food (roots, etc..) Can paddle in water. Long strong legs digging, wading in shallow water. heron - long foot for balance, long legs for wading along rocky, sandy or muddy shorelines. duck - webbed feet for propelling along water surface. Short legs, muscular for swimming. ptarmigan - fur covered for winter warmth, helps widen foot for snowshoe effect. Clawed for digging. eagle - strong leg foot for grasping prey. Talon (sharp claws) killing and grasping prey.Rough feet bottom to hold slippery fish prey. sparrow - foot shaped to perch (grasp and hold a branch), talons to dig for insects. pheasant - strong foot with extra talons for digging. bird lives on surface, foot is good for running.
