- Adaptations
- Desert Animals
- Large Surface Area Compared to Volume
- Lets Desert Animals
lose more body heat
- helps stop
overheating
- Efficient With Water
- producing small amounts
of concentrated urine
- produce very little sweat -
camels tolerate changes in heat,
kangaroo rats live in burrows
underground
- Good in Hot Conditions
- Very thin layers of body fat and a thin coat
to help them lose body heat - camels keep
nearly all of their fat in their humps
- Camouflage
- A sandy colour gives good
camouflage - to help them avoid
predators or sneak up on prey
- Arctic Animals
- Small surface area
compared to volume
- Compact rounded shape -
keeping SA to a minimum
(reduces heat loss)
- Well insulated
- Thick layer of blubber - for
insulation (also an energy
store for when food is scarce
- Thick hairy coats to keep body
heat in and greasy fur sheds water
(this prvent cooling due to
evaporation
- Camouflage
- Arctic animals have
white fur to blend in
with the snow - to
help avoid predators
or sneak up on prey
