What is the complex invertebrate flatworm sponge coral or crab?
I had asked the same thing before but then I figured it out. Out of a flatworm, sponge, coral, or crab, the complex invertebrate is a crab.
What eats flatworms in the ocean?
Flatworms have many predators, including aquatic insects, such as dragonfly naiads and diving beetles. Tadpoles, small fish, and crustaceans also eat them.
Parts grow back through the process of fragmentation.
What is sporocyst larva of fasciola hepatica?
A sporocyst is an elongated sac that protects immature larva of trematodes until they are ready to 'hatch.' Fasciola hepatica is a common liver fluke. Eggs are released into water where they hatch. The resulting hatching miracidia then find a snail host. Sporocysts are then formed and matured in the snail's digestive gland until the cercariae hatch and leave the snail.
How many holes does a flatworm have?

No, flatworms do not have a placenta. They are simple, aquatic invertebrates that belong to the phylum Platyhelminthes, and they reproduce primarily through asexual means (such as fission) or sexual reproduction without the presence of advanced structures like a placenta. Instead, flatworm embryos develop outside the parent's body, often in egg cases or directly in the environment.
Why are structure for locomotion lacking in parasitic flatworms and roundworms?
Yes, this lego set contains a 1x1 lego stud and it is also for children ages 2+
Why don't tapeworms die out with medication?
Because of environmental contamination. Tapeworms shed eggs into the environment and those eggs then turn into the next generation of tapeworms. Treatment of tapeworms with medication only kill the adult tapeworms currently residing in that animal, but the environment and other animals remain a source of eggs and adult tapeworms.
Is a ragworm in the flatworms groups?
No, ragworms are polychaetes under phylum Annelida (rounded worms). Platyhelminthes are the flat worm phylum.
To catch a flatworm, you can start by searching in damp, shaded areas such as under rocks, leaf litter, or in freshwater habitats like ponds and streams. Use a small net or container to gently scoop them up, being careful not to damage their delicate bodies. Alternatively, you can attract them using a bait like decaying organic matter. Once caught, place them in a suitable container with some water and a lid to prevent escape.
