Why the Oldest Fish in the World Lives in a Desert

The video discusses the Buffalo fish, a freshwater species known for its longevity, with some living over 100 years. Originally from the Great Lakes and Mississippi River, they were introduced to Arizona's Apache Lake in 1918. Despite being in a non-native environment, they thrive and exhibit remarkable aging characteristics, such as improved immune function. Research, aided by citizen scientists, highlights their longevity and the challenges they face in their native habitats due to overfishing. The study underscores the importance of citizen science in understanding and conserving these unique fish.

What makes the Buffalo fish in Apache Lake particularly special?

• They are the only fish species in the lake.

• They have a unique diet compared to other fish.

• They are known for their exceptional longevity.

• They are native to the Arizona desert.

Which other animal genus is known to have species with a maximum age over 100 years?

• Parrots

• Turtles

• Elephants

• Rock fishes

What did the 2021 study reveal about older big mouth Buffalo fish?

• They have a shorter lifespan than younger fish.

• They tend to have improved immune function and lower stress levels.

• They are more susceptible to diseases.

• They stop growing after a certain age.

Why is Apache Lake a better place for studying Buffalo fish longevity?

• It is easier to access than their native range.

• The fish are at risk of extinction in their native range due to overfishing.

• The lake has a higher population of Buffalo fish.

• The water temperature is ideal for their growth.

How did researchers determine the age of Buffalo fish in the study?

• By analyzing their diet.

• By examining the otolith in their inner ear.

• By observing their swimming patterns.

• By measuring their size.
