What does flatworms do to dogs. whats there sympthons

They live in flat water. nah just jokes i dont know. i think salty

Ganglia are nerve clusters. I don't know if flatworms have them or not; if they do, they probably function more or less like a rudimentary brain.

1)Bilaterally symmetrical.
2)Body having 3 layers of tissues with organs and organelles.
3)Body contains no internal cavity.
4)Possesses a blind gut (i.e. it has a mouth but no anus)
5)Has Protonephridial excretory organs instead of an anus.
6)Has normally a nervous system of longitudinal fibres rather than a net.
7)Generally dorsoventrally flattened.
8)Reproduction mostly sexual as hermaphrodites.
9)Mostly they feed on animals and other smaller life forms.
10)Some species occur in all major habitats, including many as parasites of other animals.

Flatworms belong to the phylum platyhelminthes.

Yes, asexual reproduction is advantageous to free-living flatworms as it allows for rapid population growth in stable environments without the need for a mate. This method, often through fragmentation or regeneration, enables flatworms to quickly exploit available resources and adapt to favorable conditions. Additionally, asexual reproduction ensures the survival of successful genetic traits within a population, which can be beneficial in consistent habitats. However, it may limit genetic diversity compared to sexual reproduction.

Tapeworms obtain nutrients by directly absorbing them through their skin, or tegument, which is lined with microvilli that increase surface area for absorption. They inhabit the intestines of their hosts, where they can efficiently uptake digested food, such as glucose and amino acids, as it passes by. This adaptation allows them to thrive without a mouth or digestive system, relying instead on the host's digestive processes.

Yes, Schistosoma haematobium, the causative agent of urinary schistosomiasis, requires a secondary host, specifically freshwater snails of the genus Bulinus, to complete its life cycle. The adult worms reside in the human host's blood vessels, where they produce eggs that are excreted in urine. When these eggs reach freshwater, they hatch and infect the snails, where they develop into cercariae, which can then infect humans. Thus, both human and snail hosts are essential for the parasite's lifecycle.

Flatworms have a simple body structure characterized by a lack of specialized respiratory and circulatory systems, relying instead on diffusion for gas exchange and nutrient distribution. This limits their size because as organisms grow larger, the surface area-to-volume ratio decreases, making it inefficient for diffusion to meet their metabolic needs. Additionally, their flattened shape aids in maximizing surface area but restricts them from developing into larger, more complex forms. Consequently, flatworms are generally small and rely on moist environments to facilitate their physiological processes.
