Answers Explained
Q: Why does the cheetah run so fast?
A: Specialized anatomy — flexible spine, semi-retractable claws, large nostrils and liver.
The cheetah's flexible spine acts like a spring, allowing strides of up to 7 metres. Its semi-retractable claws provide grip like running spikes. Despite this speed, cheetahs tire quickly and need 15–30 minutes to recover after a sprint.
Q: What makes octopus blood blue?
A: Haemocyanin — a copper-based oxygen carrier instead of iron-based haemoglobin.
Haemocyanin is found in many molluscs and arthropods. It is less efficient than haemoglobin at carrying oxygen, but works better in cold, low-oxygen environments like the deep sea. When oxygenated, haemocyanin turns blue; when deoxygenated, it becomes colourless.
Q: How do insects breathe?
A: Through a network of tiny tubes called tracheae that carry oxygen directly to cells.
Insects do not have lungs. They breathe through openings called spiracles along their bodies, which connect to a network of tracheal tubes. This system limits insect size — larger insects can't get enough oxygen through tracheae, which is why giant insects no longer exist.
Q: Why can axolotls regrow limbs but humans can’t?
A: Axolotls keep a pool of flexible stem-like cells at the wound site that rebuild the exact missing tissue.
When an axolotl loses a limb, cells near the wound partially reprogram into a mass called a blastema, which regrows bone, muscle, skin and nerves in the right shape. Human wounds instead form scar tissue, which is faster to close but permanently blocks regeneration.
Frequently Asked Questions
What is the fastest land animal?
The cheetah (Acinonyx jubatus) is the fastest land animal, capable of reaching speeds up to 112 km/h (70 mph) in short bursts over distances up to 500 metres.
How long can a blue whale live?
Blue whales can live up to 80–90 years. They are the largest animals ever known to have existed on Earth, reaching lengths of up to 30 metres and weighing up to 173 tonnes.
What is the only mammal capable of true flight?
Bats are the only mammals capable of sustained, powered flight. Bats belong to the order Chiroptera and represent about 20% of all classified mammal species worldwide.
How many hearts does an octopus have?
An octopus has three hearts. Two branchial hearts pump blood through each of the two gills, while the third (systemic heart) pumps blood through the body.
Which animal has the strongest bite force?
The saltwater crocodile has the strongest bite force of any living animal, up to 3,700 psi (16,460 newtons) — more than twice that of a great white shark.
How many bones does a giraffe have in its neck?
Only seven cervical vertebrae — the same number as a human neck. Each vertebra can be over 25 cm long, which is why the neck can be up to 2 metres in total.
