Annelids breathe through their body wall and parapodia expands the surface area of the animal. Annelids, or earthworms, do not have lungs to breathe with. These creatures actually breathe through ...


clams and earthworms are very different because an earthworm does not breathe through gills or by absorbing oxygen through their skin but all these things clams can do but clams can not live on ...


Leeches do not have any definite respiratory organs. Therefore, they do not have a specific respiratory system, but they recieve oxygen and expel carbon dioxide in a very similar way to earthworms. It is a gas exchange through the epidermis. The capillary beds exchange gases directly through the epidermis and into the blood.


Breathe through gills, land dwellers respire through moist skin. How do aquatic annelids respire differently than land dwelling annelids? secreting mucus. How do annelids keep their skin moist? longitudinal and circular. What are the two major groups of annelid body muscles called?


Annelida (ənĕl´Ĭdə) [Lat., anellus=a ring], phylum of soft-bodied, bilaterally symmetrical (see symmetry, biological), segmented animals, known as the segmented, or annelid, worms.Over 12,000 known species are grouped in three classes: the earthworms and freshwater worms (oligochaetes), the leeches (hirudineans), and the marine worms (polychaetes).

Diffusion: Allowing Earthworms to Breathe The segmented, wriggly worms we know as earthworms are part of the phylum Annelida. More than 5,500 named species can be found all over the world, with the exception of polar and arid climates. While earthworms vary greatly from other living


Annelids(Earthworms) STUDY. PLAY. what is an annelid? a segmented worm of the phylum Annelida, such as an earthworm or leech. ... What do aquatic annelids breathe through? gills. What do terrestrial annelids breathe through? skin. How can an annelid die? if it is not moist and dries up.


The internal organs of annelids include a close, segmentally-arranged circulatory system. The internal organs are also well developed. The digestive system includes the mouth and anus, which is a complete tube. The nervous system includes cephalic ganglia that run the length of the animal. ... Leeches breathe through their body wall, whereby ...


The Polychaeta / ˌ p ɒ l ɪ ˈ k iː t ə /, also known as the bristle worms or polychaetes, are a paraphyletic class of annelid worms, generally marine. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin.As such, polychaetes are sometimes referred to as bristle worms.More than 10,000 species are described in ...


They have a special skin that allows them to “breathe” oxygen right through it. How does this work? It has to do with a science concept called diffusion. Diffusion is the movement of molecules from an area of higher concentration (think crowded) to an area of lower co ncentration (less crowded). Diffusion allows an earthworm to get the ...
