Question 1

True or false: Weddell seals can survive entirely without ever coming onto land, living their whole lives on ice or in water.

Accepted Answer

True. They are true ice seals, rarely hauling out on land. They breed, molt, and rest on sea ice, never needing solid ground.

Question 2

True or false: Weddell seals use echolocation to navigate and find prey in dark, icy waters.

Accepted Answer

False. They rely on vision and whiskers sensitive to water movements, not echolocation like dolphins or bats. Sound is used for communication.

Question 3

True or false: Weddell seals have special teeth that let them carve breathing holes in sea ice up to several feet thick.

Accepted Answer

True. Their canine and incisor teeth are adapted for sawing through ice, allowing them to maintain access to air in frozen environments.

Question 4

True or false: Weddell seal pups gain weight so fast that they can triple their birth weight in just two weeks.

Accepted Answer

True. Mother’s milk is extremely rich in fat, allowing pups to gain about 2-3 kg per day, tripling weight rapidly before weaning.

Question 5

True or false: Weddell seals migrate thousands of miles each year to escape the harsh Antarctic winter.

Accepted Answer

False. They are non-migratory and stay near Antarctica year-round, even in winter, maintaining breathing holes in the ice.

Question 6

True or false: Weddell seals can hold their breath for up to 90 minutes while diving under Antarctic ice.

Accepted Answer

True. They are exceptional divers, capable of staying submerged for over an hour, thanks to high blood oxygen stores and a slow heart rate.

Question 7

True or false: Female Weddell seals are larger and heavier than males, a trait uncommon among seals.

Accepted Answer

False. Actually, males are slightly larger. This surprises many because in some seal species females are bigger, but not in Weddell seals.

Question 8

True or false: A Weddell seal’s vocalizations can be heard underwater by other seals from over 30 miles away.

Accepted Answer

False. While they are very vocal, their sounds typically travel only a few miles. The claim of 30 miles is an exaggeration.
