The Sneaky Salamander

Problem illustration

The olm is a blind salamander that lives deep in caves in Europe. For a long time, scientists believed these creatures spent their entire lives in the dark, underground water. But a recent study revealed a surprise! Researchers discovered that olms will actually travel to the surface, even during the daytime, to hunt for food like earthworms. This changes what we know about these amazing animals that only lay eggs about once every 12 years! Learn more!

Wee Ones

An olm has 2 feathery gills on its head and 2 tiny front legs. Can you show me that many fingers on your hand without counting them one by one?

Little Kids

An olm is hunting for a snack. It finds a group of 16 earthworms and eats 9 of them. How many earthworms are left?

Big Kids

If a mother olm lays eggs only once every 12 years, how many times will she lay eggs in 36 years?

The Sky's the Limit

An olm is exploring its cave. It swims 8 metres straight down one tunnel, then makes a sharp 90-degree turn and swims another 6 metres. What is the straight-line distance from its starting point to its ending point? (Hint: Imagine the path from above, like a map).
