How do flukes attach to their host?

How do flukes attach to their host?

Flukes usually have an oral sucker on their anterior end, sometimes ringed with hooks, that is used to attach themselves to the host’s tissues. The ciliated larval form, called miracidia, emerge from the eggs and swim until they find the appropriate species of their intermediate host: usually a snail.

Do flukes have eyespots?

Most of these flatworms are carnivorous feeding on small invertebrates and dead organisms. They do have “eyespots” which do not form images but can detect light. Adult flukes live in vertebrates (typically fish), and the secondary hosts are usually invertebrates (typically snails).

Do flukes have a scolex?

Whereas flukes are flattened and generally leaf-shaped, adult tapeworms are flattened, elongated, and consist of segments called proglottids. The scolex contains the cephalic ganglion, or “brain,” of the tapeworm nervous system. Externally, the scolex is characterized by holdfast organs.

What are symptoms of blood flukes?

Schistosomes are water-borne flatworms or blood flukes that enter the human body through the skin. Some symptoms of schistosomiasis include fever, arthralgias, abdominal pain, bloody diarrhea, and hematuria. Ultimately, patients develop heptosplenomegaly, ascites, and lymphadenopathy.

Can you pee worms out?

Why is there a worm in my urine?
