The narwhal looks like a cross between a whale and a unicorn with its long, spiraled tusk jutting from its head.
Narwhals spend their lives in the Arctic waters of Canada, Greenland, Norway and Russia.
Males most commonly have tusks, and some may even have two. The tusk, which can grow as long as 10 feet, is actually an enlarged tooth.
Whales, like the narwhal, are at the top of the food chain and have an important role in the overall health of the marine environment.

There multiple ways you can help narwals. Most importantly, visit Defenders.org for more info
The red panda is slightly larger than a domestic cat with a bear-like body and thick russet fur.
Almost 50 percent of the red panda's habitat is in the Eastern Himalayas. The loss of nesting trees and bamboo is causing a decline in red panda populations across much of their range because their forest home is being cleared.
We can help the Red Panda by donating money to numerous organizations, and helping deforestation come to a stop.
Penguins are a family of 17 to 19 species of birds that live primarily in the Southern Hemisphere.
The Antarctic Peninsula, where half of the world's emperor penguins and 70% of the Adelie penguins can be found, is heating up faster than the global average and melting the sea ice that the penguins depend on for places to breed and access to food.
To help Penguins, we should first and formost, try to prevent climate change. On top of this, if there's ever oil spills near you; get invloved!

Tigers are the largest members of the cat family and are renowned for their power and strength.
Tigers live alone and aggressively scent-mark large territories (up to 100sq km in size) to keep their rivals away.
We need to end the use of tiger parts in cloathing, and help stoaping poachers! One of the best things you can do to help tigers is to donate to a foundation and buy non-tiger leather items.
