The lizard is well-adapted to live in human dwellings. Which function of its adaptations is incorrectly described?


  Adaptation Function
A Long, sticky tongue To catch fastmoving prey
B Long, narrow and flat body To crawl between narrow crevices and spaces easily
C Sticky pads on the underside of the feet To walk on walls and ceilings without falling
D Tail that can drop off and wriggles for a while. To attract mates for reproduction


Lizards, if get captured by the tail, shed (drop off) the tail and are able to flee. The detached tail continues to wriggle for some time creating a deceptive sense of continued struggle and distracting the predator’s attention from the fleeing prey animal. The lizard can partially regenerate its tail over a period of weeks. Thus, it is a self-defense mechanism to elude a predator’s grasp and not to attract mates for reproduction.
