  • Thick coat insulates from heat
  • Leathery mouth to eat thorny plants
  • Long eyelashes keep out dust
  • Can close nostrils to keep out dust
  • Wide feet prevent sinking in sand
• Camel functional adaptations


  • Produce concentrated urine and dry feces to reduce water loss
  • Tolerate large changes in body temperature
• Kangaroo rat adaptations


  • Nocturnal to avoid daytime heat
  • Live in underground burrows to stay cool and avoid predators
• Arctic fox adaptations


  • Thick fur for insulation
  • Fur on soles of feet to reduce heat loss
  • Small ears to reduce surface area and heat loss
  • Camouflage coat for hunting
• Cactus adaptations


  • Small leaves or no leaves to reduce water loss
  • Spines to protect from animals
  • Extensive shallow roots to catch rainwater
  • Ability to store water in stem
