Read carefully, and then decide.
To determine which of the given options is NOT a characteristic of reptiles, we will analyze each option and their association with reptiles.
A) Internal temperature regulation: Reptiles are ectothermic animals, which means they rely on external sources of heat to regulate their body temperature. This is indeed a characteristic of reptiles.
B) Internal fertilization: Reptiles have internal fertilization, where the male deposits sperm inside the female's reproductive tract for fertilization. This is another characteristic of reptiles.
C) Oviparous: Reptiles are known for being oviparous, meaning they lay eggs that hatch outside the body. This is also a characteristic of reptiles.
D) Temporal holes in the skull: Temporal holes in the skull are a characteristic unique to reptiles. These holes, known as temporal fenestrae, are openings in the side of the skull that serve as attachment points for jaw muscles. Therefore, this option does not belong to the characteristics commonly associated with reptiles.
Based on the analysis, the correct answer is D) Temporal holes in the skull, as it is not a characteristic of reptiles.
