Biology Trivia Questions, From Cells to Strange but True: how it works
Which sea animal has three hearts, and which base is the fixed partner of adenine? These 177 biology trivia questions and answers run in six rounds, from cells to strange but true. Tap a choice, press Check answer, and read why.
Pick a round, then a level
Set Topic to one of six rounds: Cells and genetics, Plants, Animals, Ecology and habitats, Evolution and classification or Strange but true. Show only narrows the run to General, the 97 a pub table can answer, or High school, the 80 that use classroom words such as codon, trophic level and homologous structures.
Host it for a class or a table
Host a round shows each question large, holds the answer until you press Show the answer, and tallies two to six teams. For paper, Print question sheet lays out the next 20 questions of the chosen round, and Print answer key adds the reasons.
Tips
- For funny biology questions and answers, start with Strange but true: the hagfish that knots itself, the hippo that makes its own sunscreen.
- Revising alone? Exam mode draws 20 questions and marks them together at the end, and Missed keeps the ones to go over.
- Read the reason aloud. The giraffe answer lands better once the table hears that each neck bone is over 28 cm long.
Questions and answers
Are these trivia questions biology teachers can use in class?
Yes. The High school tag marks 80 questions in the language of a classroom course: meiosis, xylem and phloem, carrying capacity, the three domains of life. The host view puts one question on the projector at a time and keeps the team scores.
Why is there no round on the human body?
Human anatomy is kept out on purpose so that it can have a pack of its own. Nothing here asks about bones, organs or blood groups. The six rounds stay with cells, plants, animals, habitats, evolution and oddities of nature.
What is in the strange but true round?
Forty oddities that are real: the jellyfish that can return to its young stage, the fungus that steers ants, the beetle that finds its way by the Milky Way, the clam that lived 507 years. Each reason gives the detail that makes it believable.
How were the answers checked?
Each answer was read in the Wikipedia article linked under its question on September 19, 2026, along with every fact in the reason. Disputed records are left out or given as a range, such as 272 to 510 years for the Greenland shark.
