Twelve Incredibly Odd Endangered Creatures1. Solenodon
The solenodon is a mammal found primarily in Cuba and Hispanola. The species was thought to be extinct until scientists found a few still alive in 2003. Solenodons only prefer to come out at night. They eat primarily insects and they are one of the few mammal species that are venomous, delivering a very powerful toxin. Symptoms of a solenodon bite are very similar to a snake bite, including swelling and severe pain, lasting several days.
