What is it?

The Hispaniolan solenodon is one of the rarest and most ancient small mammals on Earth. It looks a bit like a large shrew with a very long, flexible nose and big claws for digging. Its family has lived on the island since before the dinosaurs disappeared โ€” roughly 76 million years ago โ€” making it a true living treasure.

Tell me more

The solenodon is one of the very few mammals in the world that produces venom. Its saliva contains a toxic liquid that it delivers through grooves in its lower teeth when it bites insects or small prey. This makes it special among small furry animals.

It comes out mostly at night to snuffle through the leaf litter on the forest floor with that extraordinary long nose. The nose is so flexible it can bend in any direction, helping the solenodon feel vibrations in the soil to find grubs, worms and beetles hiding underground.

Solenodons move in a wobbly, clumsy-looking way that actually helps them change direction very quickly if something surprises them. Despite looking slow, they can sprint surprisingly fast over short distances.

Because Hispaniola is an island, the solenodon evolved in isolation for millions of years with almost no predators. That is why it survived so long with such an unusual body plan. Scientists are still learning new things about this remarkable creature.

Discussion prompts

  1. 01The solenodon survived for 76 million years by living on an island with few predators. What might happen if new animals arrived on the island?
  2. 02Very few mammals are venomous. Can you name another mammal that uses venom? (Hint: think of a small burrowing animal.)
  3. 03Why is it exciting for scientists to find an animal alive that they thought might have disappeared?

Create a 'creature fact file' for the solenodon. Draw it in the middle of the page, then draw arrows pointing to six features (nose, claws, teeth, eyes, tail, fur) and write one fascinating fact next to each arrow.
