26. Solenodon (Solenodon paradoxus)

The solenodon is a rare, shrew-like mammal with a long, flexible snout, coarse reddish-brown fur, and a poisonous bite. It scurries through the forests of Haiti and the Dominican Republic, active mostly at night.
Its venom makes it one of the strangest mammals alive. Unlike snakes, the solenodon delivers toxic saliva through grooved teeth in its lower jaw—strong enough to kill prey quickly. It is one of only a few venomous mammals on Earth. Adults over 40 who thought venom was reserved for reptiles or insects are stunned to learn this “living fossil” (unchanged for 76 million years) still roams the Caribbean, quietly packing a deadly punch in its tiny jaws.
