Worms do not need a skeleton as, unlike many animals of the same build, they interact with the environment differently. Worms have no need for a skeleton as they mostlly live in the earth. Therefore through everlution have lost the chemical, Phyniside, that "orders" the new cells of the organism to "become" part of the skeleton.
Because they live in the earth, so therefore they don't need the skeleton, unlike us.
No, worms do not have any skeleton at all.
Every species has its own particular specialty or adaptation. There are all sorts of organs and systems that worms do not have; they have no skeletons, no wings, no eyes, no claws, no feathers, and so forth. They are simple organisms that are well adapted to their particular ecological niche. They don't need skeletons.
No, worms generally have hydrostatic skeleton, they possess no vertebral column
Worms and snails do not have an inside skeleton- but pigs do.
No it does not. Earth worms do not have bones.
Yeah, Of course they does ... besides shellfish and bugs with exoskeletons, only worms don't have any sort of skeleton.
Snakes have a skeleton - worms don't.
Creatures need a water skeleton, or hydrostatic skeleton, as it provides structural support and maintains shape without the rigidity of a hard skeleton. This type of skeleton relies on fluid pressure within a body cavity, allowing for flexibility and movement, particularly in soft-bodied organisms like jellyfish and worms. It also plays a crucial role in locomotion and helps protect internal organs. Overall, a water skeleton is essential for survival in various aquatic environments.
