50 free Whale Shark trivia questions with answers — nature quiz, new questions added Aug 2026.
This whale shark trivia quiz covers the largest fish alive: how long it really gets and why the record is so hard to pin down, how its 20 filter pads strain 6,000 litres of water an hour, why its blue-tuned rhodopsin lets it see at both the surface and 2,000 m down, the 300-pup pregnant female of 1996, and the 80-130 year lifespan measured against Cold War bomb-test carbon. It also covers whale sharks and people: Andrew Smith's 1828 Table Bay specimen, the giant tales of Wright and Hugh M. Smith, the 400-shark gathering off Yucatan, 'Rio Lady' and her 7,772 km trip, the Philippine 100-peso note, the names marokintana and jinbei-zame, Okinawa Churaumi's 26-year resident, Georgia Aquarium's imports and the fishing bans that followed. Every question was verified against a primary reference (the Wikipedia article on the whale shark) and carries a citation. Play it with our great white, hammerhead and ocean quizzes.

Q 01What distinction does the whale shark hold?
Largest living fish
It is by far the largest living non-cetacean animal; only the whales beat it.
Q 02What is the whale shark's scientific name?
Rhincodon typus
Cetorhinus is the basking shark and Megachasma the megamouth, the only other filter-feeding sharks.
Q 03How long was the individual considered the largest reliably recorded whale shark?
18.8 metres
A female from the Arabian Sea in 2001, with a standard length of 15 m; a 2015 megafauna review rated it the most reliable measurement.
Q 04Despite its name, what kind of animal is the whale shark?
A cartilaginous fish
The name refers only to its size and look; like all sharks it is not closely related to whales.
Q 05Where was the specimen harpooned in April 1828 that led to the species being described?
Table Bay, South Africa
Military doctor Andrew Smith described the 4.6 m animal the following year.
Q 06How much water can a whale shark process per hour through its gill pads?
Over 6,000 litres
The 20 sieve-like pads are presumed to be modified gill rakers.
Q 07Where is the whale shark's mouth positioned, unlike most sharks?
At the front of the head
One 12.1 m animal had a mouth 1.55 m across.
Q 08How many rows of tiny teeth can a whale shark's mouth contain?
Over 300
They are vestigial and play no role in feeding.
Q 09How thick can a whale shark's skin be?
Up to 15 cm
It is very hard and rough, with a spot-and-stripe pattern unique to each individual.
Q 10What unusual protective feature do whale shark eyeballs have?
Dermal denticles on their surface
They can also retract the eyes deep into their sockets.
Q 11Two mutations tune the whale shark's rhodopsin to which colour of light, dominant in the deep sea?
Blue
The pigment is unstable in warm shallow water, so the shark switches it off there and back on at 2,000 m.
Q 12Which sex of whale shark grows larger, according to a 2020 Western Australian study?
Females
Males average 8-9 m; the study estimated females at around 14.5 m.
Q 13Below what water temperature are whale sharks rarely found?
21 °C
They roam mostly between 30°N and 35°S but have turned up in the Bay of Fundy and the Sea of Okhotsk.
What is the deepest recorded whale shark dive?
Q 21How do female whale sharks appear to space out their births?
They store sperm and produce pups over a prolonged period
Pupping has never been observed; mating has been seen only twice, at St Helena.
Q 22The smallest living whale shark ever found, in 2009, measured how long?
38 cm
It was tied to a stake on a Philippine beach and released, suggesting the area is a birthing ground.
Q 23What share of whale sharks observed around Darwin Island in the Galápagos were mature cows in one study?
91.5%
Many were pregnant, suggesting the site matters for reproduction.
1,928 metres
About 95% of their oscillating time is spent above 200 m.
Q 15What share of the world's whale sharks belong to the Indo-Pacific subpopulation?
75%
The Atlantic subpopulation ranges from Maine and the Azores to Cape Agulhas.
Q 16In 2009 over 400 whale sharks gathered off which coast, one of the largest gatherings ever?
The Yucatan, Mexico
They stay 24-33 days on average, and ecotourism there has grown to unsustainable levels.
Q 17Which Western Australian site hosts a famous seasonal whale shark aggregation?
Ningaloo
Mating was filmed there from an aircraft for the first time in 2019.
Q 18A 2020 study confirmed whale shark vertebral growth bands are annual by comparing them to what?
Carbon-14 from 1950s-60s nuclear tests
It aged a 10 m female at 50 and a 9.9 m male at 35.
Q 19What is the estimated lifespan of a whale shark?
80 to 130 years
Males may not mature until about 25.
Q 20A female whale shark caught in 1996 was carrying roughly how many pups?
About 300
That proved the species is ovoviviparous; pups are 40-60 cm at birth.
Q 24How far did the whale shark 'Rio Lady' swim in 150 days from the Yucatan toward the Mid-Atlantic Ridge?
7,772 km
She dived to 1,600 m throughout, possibly heading for an open-Atlantic pupping ground.
Q 25Which are the only other two filter-feeding species in the whale shark's group?
The basking and megamouth
The basking shark feeds passively by swimming; the whale shark can also suck water in while stationary.
Q 26Whale sharks are technically omnivores because they ingest and partly digest what?
Sargassum seaweed
They also eat clouds of fish and coral eggs during mass spawnings, and Christmas Island red crab larvae.
Q 27What method separates food from water on a whale shark's filter pads?
Cross-flow filtration
Water runs nearly parallel to the pad surface, so it barely clogs; the shark 'coughs' to clear the rest.
Q 28How much plankton is a juvenile whale shark estimated to eat per day?
21 kg
That mode of feeding also makes them prone to swallowing microplastics.
Q 29How does the IUCN classify the whale shark?
Endangered
The population has fallen by more than 50% in 75 years, chiefly from fishing, bycatch and ship strikes.
Q 30What is the current estimate of the global whale shark population?
130,000 to 200,000
Declines are about 63% in the Indian and Pacific Oceans and over 30% in the Atlantic.
