Earthworms lack appendages to prevent getting stuck in burrows, as they move by elongating and contracting their bodies. This streamlined form allows them to navigate through soil easily. Additionally, not having appendages reduces surface area, helping them move efficiently through their burrowing activities.
lala that's what I think
An earthworm's lack of appendages helps reduce drag as it moves through the soil, making burrowing more efficient. The worm's cylindrical shape also allows it to move easily through tight spaces underground. Additionally, the lack of appendages minimizes the risk of getting stuck in narrow tunnels.
Dead plants and animals would pile up if it were not for the earthworms.
If it is a rainy day some might show up. You can buy earthworms too.

Due to the rigidity of the arthropod exoskeleton, the safest answer might be "jointed' ones - hence the phylum's name Arthropoda, from the Greek, meaning, jointed appendages. They do evidence a variety of appendages: legs, pincers, wings, swimmerets, antennae, tails, etc., depending on what environment and food source they are adapted to.

Adaptation
One example of a daily adaptation is adjusting your clothing to match the weather outside. If it's cold, you might wear a jacket; if it's hot, you might wear shorts. This adaptation helps regulate your body temperature and keep you comfortable throughout the day.
