Eli5 Why cockroaches and other insects die facing upwards?
In: 9
Insects actually use a combination of hydraulics and muscle flexing to move their limbs. To extend their legs they push fluid into them, and to contract them their muscles pull the joints closed. When they die the hydraulic pressure is no longer present and their legs will curl inward, which tends to cause them to turn over since their body is so much heavier than the rounded cage of their inwardly flexed legs.
