Chapter 732: Dim Specimen

The two leisurely strolled down the butterfly exhibit's path, admiring the various beautiful butterflies.

By reading the informative display boards along the route, they also learned a lot about butterflies.

For instance, butterflies do not have a heating system in their bodies and must bask in the sun to regulate their body temperature, using their wings to adjust heat.

When the sun shines directly, the scales automatically open up to reduce the angle of the sun's rays, absorbing less heat from the sunlight; when the outside temperature drops, the scales automatically close, sticking closely to the body, allowing the sun to shine directly on them to absorb more warmth.

In this way, they keep their body temperature within a normal range.

The temperature control system on artificial satellites was designed after the butterfly's scales.
