Activity

In your groups, you have three signs sitting in front of you: SAFE ENDANGERED EXTINCT

I’ll put up a picture of a living organism, and in your group, you’ll have 10 seconds to discuss if you think its safe, endangered, or extinct. When you hear the buzzer, hold up your team decision.

Whoever gets the most right, gets +100 points on the Jeopardy review tomorrow!

Pescado Stubfot Toad

Endangered!

This toad, which lives in Southwestern Ecuador has been threatened by habitat destruction due to logging and agricultural expansion.

We don’t know how many are left!

Aardvark

Sheath Tailed Bat

Endangered!

There are only 100 of these bats left! They only live in caves in Seychelles.

Habitat destruction and predation by invasive species have decreased its numbers.

How to help? Remove the invasive vegetation and control the

introduced predators, along with legal action.

West African Black Rhino

Extinct!

These rhinos were declared extinct in 2006 and their last remaining habitat was in Cameroon.

Poachers hunted the rhino for its horn!

Tarzan’s Chamelon

Endangered!

We don’t know how many of these cool chameleons are left!

Only live in eastern Madagascar, and are threatened by habitat loss from growing agriculture.

Action needed? Support for community conservation and

protection of its habitat!

Harris’s Hawk

Golden Toad

Extinct!

These beautiful toads was a fluorescent amphibian found in Costa Rica, but due to pollution and global

warming, they became extinct in 1989.

Pale Throated Sloth

Araipe Manakin

Endangered!

779 individuals remaining!

Live in Brazil, and have dwindling numbers because of increased agriculture and water diversion.

How we can help? Need legal protection of their environments,

and protection of the springs and streams!

Geometric Tortoise

Western Spotted Skunk

Endangered!

We don’t know how many are left, but they live in South Africa

The main threats are habitat destruction and degradation. They’ve also been hunted.

We need to create reserves and manage fires in these regions!

Spix’s Macaw

Extinct!

These beautiful blue bird doesn’t exist in the wild anymore. Habitat destruction and illegal trapping

has decreased the numbers of this bird dramatically.

Dark Sided Thrush

Rosa Arabica

Endangered!

Yes, flowers can be endangered too guys!

There are only 10 sub populations of these remaining, and they lie primarily in Egypt.

These pretty flowers have many medicinal values, but because of animal grazing, climate change, and drought, many have been lost!

We need to protect against human exploitation!

Fat Tailed Dwarf Lemur

Passenger Pigeon

EXTINCT!

These pigeons were hunted as crop. These birds used to

be all over the skies less than 100 years ago, but humans have gotten rid of them. Last one died in 1914.

American Crocodile

Almost went Extinct…but now SAFE!

In 1975, these crocodiles were listed as endangered, but because hunting stopped for their skin and zoos

started collecting them, their population sizes went up!

You CAN help!

Just like the American Crocodile…we CAN help save animals that currently endangered.

Tomorrow: We will be thinking of creative ways we can help the earth and certain

animals!
