Answers and explanations

  1. Question: Which reptile group is defined by having a single opening (temporal fenestra) behind each eye?
    Answer: Synapsids
    Explanation: Synapsids are defined by a single temporal fenestra (opening) behind each eye; they include early mammal-like reptiles and eventually gave rise to mammals. This group is important because it marks a key step in skull evolution that allowed stronger jaw muscles and more efficient feeding, paving the
  2. Question: Which reptile famously uses limb reduction and elongated body to burrow but is not a snake?
    Answer: Glass lizard
    Explanation: Glass lizards (also called glass snakes) are legless lizards with elongated bodies that use limb reduction to burrow and move through grass and soil; they’re important because they show how lizard evolution can converge on snake-like forms. Fun fact: despite their snake-like appearance, glass lizard
  3. Question: Which venom-delivery system evolved independently in some lizards and snakes, enabling active injection?
    Answer: Hollow fangs
    Explanation: Some snakes and a few lizard species evolved hollow or grooved fangs that actively inject venom into prey — an example of convergent evolution. This adaptation allows more efficient envenomation and is key to predator success and medical importance in venomous species.
  4. Question: Which large extinct reptile order includes soaring, winged species from the Mesozoic?
    Answer: Pterosaurs
    Explanation: Pterosaurs were a diverse order of flying reptiles from the Mesozoic (about 228–66 million years ago) that included species ranging from sparrow-sized to wingspans over 10 meters; they were the first vertebrates to achieve powered flight. Their wings were formed by a skin-and-muscle membrane mainly伸
  5. Question: Which modern reptile has a four-chambered heart only partially separated by a septum?
    Answer: Crocodilians
    Explanation: Crocodilians (crocodiles, alligators, caimans, and gharials) have a four-chambered heart with an incomplete separation called the foramen of Panizza and a muscular valve that allows shunting between ventricles—useful for diving and regulating blood flow. This cardiac arrangement helps them control O
  6. Question: Which metabolic term describes reptiles' body temperature dependence on external sources?
    Answer: Ectothermy
    Explanation: Ectothermy describes animals that rely on external heat sources to regulate body temperature—common in reptiles, amphibians, and many fish. Fun fact: ectotherms often bask in the sun to raise body temperature and their activity levels strongly depend on environmental conditions.
  7. Question: Which reptile species became a cultural icon after the movie 'Jurassic Park'?
    Answer: Velociraptor
    Explanation: Velociraptor became a pop-culture icon after Jurassic Park, portrayed as intelligent, fast pack hunters (though the real animal was smaller and likely feathered). Its depiction reshaped public images of dinosaurs and sparked interest in paleontology and dinosaur science.
  8. Question: Which reptile clutch behavior—burying eggs and abandoning them—affects hatchling survival?
    Answer: Sea turtles
    Explanation: Many sea turtle species bury their eggs in sandy beaches and then leave, relying on nest placement and temperature to determine hatchling survival; temperature even influences sex ratios, so nest conditions have big impacts on populations.
