Transcript Adaptations : Black Widow Spider

Adaptations (2)
• How do plants and
animals survive?
• How do they adapt
to survive in their
chosen habitats?
Adaptations : Black Widow Spider
• Venom is about 15 times as
toxic as the venom of a
diamondback rattlesnake
• Prey includes a variety of
insects and other arthropods.
• It makes small punctures in the
victim's body and sucks out the
liquids.
The female eats the male after mating!
• Resistant to many insecticides
Adaptations : Collared Peccary
• Tough snout to overturn dead
vegetation to look for roots
and shoots.
• Can eat prickly pear cactus,
including the spines.
• Can go for days without
drinking water
• Powerful musk can aid
communication between
individuals
Adaptations : Coati
• Strong curved front claws to
move rocks and dig for food
• Powerful smell to detect prey
• Long bushy tail used for
balance
• Can easily climb trees to
forage for fruit, berries and
birds eggs.
Adaptations : Roadrunner
• Can adapt the surface area
of wings and plumage to
absorb or emit heat.
• Usually nests twice in a
year, during the seasonal
rains.
• Vibrates its throat lining
to move air past moist
respiratory tissues during
very high temperatures.
This increases evaporation
from within the bird.
Adaptations : Roadrunner
• Able to run at up to 15
miles an hour, to outrun
predators.
• Its speed also helps it to
catch prey, such as
scorpions, lizards, and
other small animals.
• Can also kill and eat
rattlesnakes. It uses its
wide rings to deflect any
striking fangs.
Adaptations : Diamondback Snake
• Has a pair of pits between
eyed to detect heat from
mammals, even at night.
• Brown/grey colour to blend
in with its surroundings.
• Uses a rattle in its tail for a
warning when alarmed.
Adaptations : Gila Monster
• Very toxic venom, used
against predators.
• Its pink or orange colour
provides perfect camouflage
in its natural habitat.
• Lives in cool burrows during
hot days.
• Thick tails provide food and
water reservoirs.
Adaptations : Round-tailed Ground Squirrel
• Its tawny coat blends well
with its surroundings
• Lives in its cool burrow
during the hottest times of
the day.
• Stands on its hind legs to
look out for predators
• Makes its home near
creosote bushes, where the
roots bind the soil together.
Adaptations : The Jojoba Plant
• A waxy coating reduces water
loss by evaporation.
• Seeds are toxic to many animals if
eaten…except Bailey’s pocket
mouse!
• Leaves face the early and late sun,
but not the midday sun. This
helps to conserve water.
• Bailey’s pocket mouse collects
and stores the seeds : so many
seeds can germinate.
Adaptations : The Ocotillo
• Loses its small leaves during dry spells.
• New leaves can grow within five days
after receiving water.
• Wide and shallow root system to collect
ground water.
• Stems are capable of photosynthesis
during dry spells
Adaptations : Teddy Bear Cholla
• Covered with sharp spines to stop
animals from eating the tissue.
• The spines cool the cholla’s
tissue in hot weather
• Stem consist of segments . The
segments provide water storage,
and allow photosynthesis to
happen.
