What is Monogenea in biology?

Monogeneans are a group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish. They have a direct lifecycle and do not require an intermediate host. Adults are hermaphrodites, meaning they have both male and female reproductive structures. Monogenea.

What is Monogenea example?

Monogenea/Lower classifications

What are Monogenea and Digenea?

The name “digenea” refers to the alternation of generations between sexually-reproducing adult and asexually reproducing larval stages. This contrasts with the Monogenea, which reproduce sexually only. Adults produce an egg. Subsequent development follows myriad routes, depending on the species involved.

How many species are in Monogenea?

There are approximately 5000 species of monogeneans described worldwide, with 318 species in 125 genera and 28 families listed in the most recent checklist of species found in Australia.

What phylum is Monogenea in?

FlatwormMonogenea / Phylum

What do you mean by Digenea?

[ dī-jē′nē-ə, dī′jə-nē′ə ] n. A subclass of parasitic flatworms characterized by a complex life cycle involving developmental stages in a mollusk intermediate host and an adult stage in a vertebrate and including all of the common flukes of humans and other mammals.

What is Digenea life cycle?

The digenean (two-host) life cycle of a parasitic trematode typically consists of a vertebrate primary host, in which sexual reproduction of the parasite occurs, and an intermediate host, typically an aquatic snail, in which the parasite reproduces asexually.

What is Turbellaria in biology?

Definition. A taxonomic class belonging to the phylum Platyhelminthes (flatworms) characterized by having a body covered externally with vibrating cilia. Supplement. The phylum Platyhelminthes (flatworms) is comprised of parasitic worms characterized mainly by their flattened, bilaterally symmetrical body.

What is the life cycle of Monogenea?

Monogeneans are usually strictly host specific, and have a single host lifecycle. Adult monogeneans are hermaphroditic and lay their eggs directly into the water, from which a free-swimming larva will hatch. The larva must infect a host to complete the lifecycle.

Are leeches Monogenea?

However, this resemblance is superficial and leeches and monogeneans are unrelated and structurally very different. The body of a leech consists of a series of segments (metameres), each of which contains the same basic components (gut, muscles, nerves, excretory organs).
