Instant Fish: Just Add Water | Salamanderfish

Salamanderfish are unique fish found in ephemeral pools in southwest WA. They survive dry seasons by burrowing into sand and entering estivation, a dormant state. Their adaptations include wedge-shaped skulls and the ability to breathe through their skin. Despite living in acidic, temperature-fluctuating water, they have thrived for millions of years. However, climate change threatens their habitat, necessitating conservation efforts.

What unique feature allows salamanderfish to survive when their pools dry up?

• They burrow into the sand.

• They migrate to the ocean.

• They develop lungs to breathe air.

• They can fly to another location.

How do salamanderfish manage to breathe while buried in the sand?

• They have a special breathing organ.

• They absorb oxygen through their skin.

• They don't need oxygen while buried.

• They use their gills to extract oxygen from the sand.
