Surviving droughts<br />
During serious droughts, African and South<br />
American lungfish dig down into the mud. As<br />
they do this they chew up wet mud and debris to<br />
take on moisture, whilst ejecting the rest through<br />
their gills. Whilst boring through the mud they<br />
leave a small hole for breathing. Once it reaches<br />
the desired depth, it then secretes a special type<br />
of mucous layer all around itself, which as it dries<br />
up forms a thin transparent cocoon in which it<br />
estivates or adopts a dormant state.<br />
The lungfish ensures that it is aligned with the<br />
small hole, which it has left, to allow it to<br />
breathe. The soil above can harden and become<br />
extremely dry but the lungfish continues to<br />
live in a dormant state with its nose pointing<br />
upward towards the hole that was created<br />
while burrowing. In this state, the lungfish can<br />
wait out the entire drought, which can last for<br />
many months and some African lungfish can<br />
actually live up to four years in that state.<br />
During this dormant state, its metabolic rate<br />
drops significantly and the required energy for<br />
surviving comes from the breakdown of its<br />
own muscle tissues.<br />
