Explanations: answer key for all 10 questions

Q1: How do reptiles control their body temperature?
Answer: Using outside heat sources
They are ectotherms.
Q2: What adaptation let reptiles breed away from water?
Answer: Shelled amniotic eggs
The egg keeps the embryo moist.
Q3: Why can reptiles go long periods without food?
Answer: They use far less energy than mammals
Some snakes eat only a few times a year.
Q4: Which reptiles detect warm prey with heat-sensing pits?
Answer: Pit vipers, pythons and boas
They can strike in total darkness.
Q5: What is brumation?
Answer: A winter dormancy in reptiles
It is similar to hibernation.
Q6: How do marine iguanas get rid of salt?
Answer: By sneezing it out
Special glands collect it.
Q7: Which reptile uses camouflage and color signals?
Answer: Chameleon
Color also shows mood.
Q8: What is autotomy in lizards?
Answer: Dropping the tail to escape
The tail keeps wriggling to distract.
Q9: What does the parietal eye of some reptiles sense?
Answer: Light and shadows
It helps regulate daily rhythms.
Q10: How do sea turtles stay underwater for hours when resting?
Answer: Slowing their metabolism
Cold water slows them further.

The Reptile Adaptations Quiz – Built to Survive

Reptiles have lived on Earth for over 300 million years and survive in deserts, forests, oceans and mountains. Their scaly skin limits water loss and their shelled eggs let them breed on land, freeing them from the need for ponds.

As ectotherms, reptiles use the Sun and warm surfaces to heat their bodies. This means they need much less food than mammals and can survive long periods without eating. Many brumate in winter and become active again when temperatures rise.

Reptiles have evolved many special tools: heat-sensing pits, venom, camouflage, tail-dropping and salt glands. These adaptations help them hunt, hide and survive, though rapid climate change and habitat loss now challenge many species.
