Adaptations for Movement 1 What is Adaptation? “...the way in which a species becomes better suited to living in its environment.” 2 Movement • There are many different methods of movement • Different habitats present different problems to movement that need to be overcome • Specialists vs. Generalists Leopard seal – aquatic specialist Good in water... ...cumbersome on land 3 Why move? American pika collecting food Common warthog fleeing from cheetah Grass snake hatchlings dispersing Radiated tortoises mating 4 Bornean orangutan Snow leopard Rainforest River Polar Desert Which habitat? Ocean Woodland Mountains Open grassland Red squirrel Nile crocodile 5 Bornean orangutan Snow leopard How are they adapted to move in their habitat? Red squirrel Nile crocodile 6 Movement on Land Adaptations to moving on land • Things to think about: • Speed vs. agility – Move to catch prey or to escape predators – Land may be open or have obstacles such as trees • Moving over different substrates e.g. sand, snow, mud 7 Cheetah • Open plains specialist • Adapted for speed Spanish ibex • Rocky habitat specialist • Adapted for agility 9 Polar bear • Habitat generalist – can move over land and in water • Adapted to polar habitat 10 Legless movement • Movement without limbs • Adapted to overcome friction Sidewinder Leopard slug 11 Arboreal Movement Adaptations to arboreal movement Things to think about: • Forested areas may not be continuous • Moving from one tree to another • Balance and grip • Fossa • Habitat generalist – can move quickly through trees as well as on the ground • Adapted to jump between branches 13 White-handed gibbon • Master of agility • Adapted to swing between branches14 Sugar glider • Arboreal specialist • Adapted to glide between trees 15 Aquatic Movement Adaptations to aquatic movement • Things to think about: • Friction – causing drag • Buoyancy – saline vs. freshwater • Currents and tides 16 Great white shark • Aquatic specialist • Adapted for speed 17 Spotted handfish • Aquatic specialist • Two different methods of moving through water 18 Aerial Movement Adaptations to aerial movement • Things to think about: • Overcoming friction • Use of air currents • Hot air vs. cold air 19 • Common swift Peregrine falcon • Aerodynamic body shape • Adapted for speed 20 California condor • Aerial movement using thermals • Adapted for gliding 21 Wild Journey - You will be given an ‘Adaptations for Movement’ worksheet. - Write in the adaptations that each species has for moving through its natural habitat. Once you have finished the worksheet, you can begin your ‘Wild Journey’ • Get into groups of 5 or less • Each group will need: • 1x Wild Journey board game • 5x Species characters - use as your playing pieces on the board • 5x Species fact files - explains how your particular species is adapted to moving through its natural habitat • 1x Rules sheet - read before beginning the game • If you land on your natural habitat square: roll the dice again. • If you land on your least suitable habitat square: miss a go!
