How long can fleas hold their breath?

Fleas can't hold their breath! They need to breathe just like any other living creature.

Here's why:

* They need oxygen: Fleas, like all insects, breathe through tiny holes called spiracles located along their bodies. They need oxygen to survive.

* They don't have lungs: They don't have lungs like humans. Instead, they have a system of tubes called tracheae that deliver oxygen directly to their tissues.

So, the next time you see a flea, don't worry about it holding its breath! It's definitely breathing, and that's how it survives.
