The earthworm has as its digestive system:
# a very primitive mouth. # a crop, a chamber where food can be ground up using the services of grains of sand and the like. It needs this as it doesn't have a mouth to do the job. # A stomach to digest food. # A REALLY long intestine. A straight hollow tube that is in-folded at the top - to give it a greater surface area to do its work on. (In cross-section think of it as a Capital letter 'O" with its top cut off and a lower-case 'u' inserted into the hole to block it) That as far as I got in the dissection. I assume that there is also an anus.
closed circulatory system
sorry that might not be the right answer but they do have a closed circulatory system
The hydrostatic skeleton facilitates movement in the earthworm.
Earthworms do not have a skeleton.
Hydrostatic skeleton
An earthworm and all insects are invertebrates because they lack an internal skeleton, especially because they don't have a backbone.Well to tell you an earthworm is an invertebrate.An earthworm is an invertebrate.
Oligochaeta.
Earthworms are scavengers/detritivores.
The ecological niche for an earthworm is decomposing the soil.
Earthworms are generally some type of a brown tone.
earthworm moves by the hair like projections called setae .
Well, an earthworm is one.
No it is not supported by an internal Skeleton of bone
Nope, They are a tubular organism with no skeletal structure
An earthworm is an invertebrate as it doesn't have an internal skeleton or a spine.
many fishes do have
Snakes have a skeleton - worms don't.
earthworms have a hydrostatic skeleton. An Earthworm is able to move with the help of a fluid-filled chambers functioning like a hydro-skeleton. The earthworm movement in the soil helps in converting large pieces of organic to matter. Earthworms keep the soil structure open through its burrowing actions.
An earthworm and all insects are invertebrates because they lack an internal skeleton, especially because they don't have a backbone.Well to tell you an earthworm is an invertebrate.An earthworm is an invertebrate.
No,it has a hydrostatic skeleton.It emerges due to pressure caused by fluids in the coelom.
Almost all animals have a skeleton, whether its an internal skeleton or an exoskeleton. Some animals like the Jellyfish are of without a skeleton, and they are very much ... jelly-like. Examples include earthworms, slugs, etc.
A hydrostatic skeleton is a type of skeleton many animals in the animal kingdom have.
