However, they have a more complicated visual system than many segmented worms. Most species of segmented worms have eyespots. Eyespots are spots on the worm that react to changes in light.
When the light moves, it sends signals to the worm to move as well. Roundworms use some of their nerves to detect changes in light. The segmented worm and roundworm have different body types. The segmented worm is made up of small segments. Most segmented worms can be cut into many pieces, and each piece will be able to support a fully functioning life. Roundworms are not like that. Roundworms are bilaterally symmetric, but they actually appear flatter than segmented worms.
Roundworms typically will not survive if cut into pieces. Reproduction differs in the two types of worms. Roundworms sexually reproduce. There are both female and male roundworms. Roundworms have sperm and eggs like many mammals.
The females lays her eggs in the soil once they are fertilized. Segmented worms have a varied reproduction cycle. Once under a microscope, the veterinarian will be able to determine the exact type of worm contaminating a pet. Treatment for worm parasites is a simple medication prescribed by the veterinarian. Prescriptions vary depending on the level of infection as well as the type of parasite.
Some medications will only kill adult worms, so a combination of dewormers might be prescribed. Alternatively, a medication might be prescribed for a prolonged period of time to ensure that the parasite is fully exterminated. Pet owners should remain cautious because some parasites will be killed off by dewormers, but can remain dormant within the host, reappearing during times of stress or when a mother gets pregnant. Also, while some pet owners may decide to administer a dewormer on their own, some parasites, such as tapeworms, are not curable with generic, over-the-counter dewormers, so a trip to the vetrinarian is necessary.
Keeping kennel areas clean, controlling rodents, and testing females prior to breeding can all help prevent the spread of parasites. Symptoms of a worm parasite in pets can include:.
Additional details about the most common parasitic worms follow. If your pet exhibits any of these symptoms, please contact our office and schedule an appointment today. They are most common in warm, humid geographical areas and most often infect puppies, though they are capable of contaminating older dogs and cats as well.
Humans are capable of contracting hookworms from their pets, though the parasite cannot survive very long in a human environment. Moreover, the appearence o f each creates another difference between Ascaris and earthworm. The ascaris is thin and smooth while earthworm has a brown, tube-like body, and moist skin.
Also, the ascaris grows up to four feet log while earthworm grows up to eight feet long. Furthermore, another difference between Ascaris and earthworm is their coelom. While ascaris has a pseudocoelom, earthworm has a true coelom. The circulatory system is also a difference between Ascaris and earthworm. Ascaris does not have blood, blood vessels or a heart while earthworm has a heart, blood vessels, and blood.
Besides these, Ascaris is parasitic on animals or plants while earthworm consumes dirt and plant matter. Their lifespan is another difference between Ascaris and earthworm. Ascaris lives about for a year while earthworm lives for two to three years. Additionally , ascaris can be either male or female while earthworm is a hermaphrodite.
Ascaris can cause diseases to animals and plants while earthworm changes the physical structure of the soil. Ascaris is a roundworm that belongs to the phylum Nematoda. It has a thin, unsegmented body and it is a parasitic worm. It also has a pseudocoelom. Generally, Ascaris causes diseases in their host.
In contrast, earthworm is a segmented worm that lives freely in the environment.
