Endemic Species and Their Unique Adaptations

The video explores various endemic species, highlighting their unique adaptations and ecological roles. It covers the Santa Cruz kangaroo rat, Texas blind salamander, marine iguana, golden jellyfish, Nosy Hara chameleon, tree lobsters, geladas, and the Inaccessible Island rail. The importance of conservation efforts to protect these species and their ecosystems is emphasized.

What is a keystone species, as exemplified by the Santa Cruz kangaroo rat?

• A species that is the largest in its habitat

• A species that is the fastest to reproduce

• A species with a significant impact on its ecosystem

• A species that is found in multiple habitats

How do Texas blind salamanders adapt to their dark cave environment?

• By having bright colors

• By developing large eyes

• By using echolocation

• By relying on movement sensing

What unique adaptation helps marine iguanas survive in the ocean?

• They have gills for breathing underwater

• They have webbed feet for swimming

• They have special glands to expel salt

• They have a diet of fish

What mutualistic relationship do golden jellyfish have in Palau?

• With algae that provide camouflage

• With fish that clean their tentacles

• With bacteria that produce light

• With zooxanthellae that photosynthesize

What is the world's smallest chameleon known for?

• Its bright colors

• Its large size

• Its ability to fly

• Its tiny size

What is the main threat to the tree lobsters of Lord Howe Island?

• Human hunting

• Invasive rats

• Climate change

• Habitat destruction

Where do geladas, the ground-dwelling monkeys, primarily live?

• In the forests of South America

• In the deserts of Africa

• In the jungles of Asia

• In the highlands of Ethiopia

What makes the Inaccessible Island rail unique among birds?

• It is the most colorful bird

• It is the smallest flightless bird

• It is the fastest flying bird

• It is the largest bird in the world

What is a potential consequence of a species being endemic to a single location?

• It may be wiped out by a single disaster

• It can easily adapt to new environments

• It has a larger population size

• It is less vulnerable to extinction

Why are some researchers focused on the welfare of unique endemic animals?

• To make them more adaptable

• To ensure ecosystems remain balanced

• To increase their population size

• To reduce their habitat range
