hydroskeleton
The segments elongate when the circular muscles contract.
When an earthworm dies, its muscles relax, causing the body to lose its cylindrical shape. Normally, the worm's body is maintained in a specific form by the tension in its muscles and the presence of coelomic fluid. Upon death, the loss of muscle tone and the inability to maintain internal pressure result in the worm's body becoming limp and flattened. This change is a natural consequence of the cessation of biological functions.
An earthworm increases its surface area to volume ratio through its long and slender body shape. This allows for more surface area relative to its volume compared to a more compact shape. Additionally, the earthworm's body is covered in moist, permeable skin, which further increases its surface area for gas exchange and nutrient absorption.
