A parasite called Heterobilharzia americana, a flatworm commonly referred to as liver fluke, was behind the illness of the 11 dogs. The parasite normally makes its home in Texas and in the South.
The portion of the body closest to the prey is the portion the flatworm utilizes to grip the prey and ingest into its midventral mouth. [1] If the flatworm has been starved, it will lunge at the prey, grip onto it, and quickly ingest it. [1] However, if the flatworm is fed daily, it attacks normally and ingests at a slower rate. [1]
Lafferty did a study to observe how a population of un-parasitized snails performs in the absence of infected snails. He found that they released more eggs and became densely populated. He proposes that the snail population in the natural environment would be nearly double what it is if it weren't for the parasite Euhaplorchis californiensis.
Pseudocerotidae is a family of flatworms which includes the Bedford's flatworm. Pseudocerotidae are simple organisms categorized by their oval bodies and tentacles [7] and bright colors. They use the cilia to glide along surfaces. [8] Most commonly referred to as marine flatworms, closely related to the orders Macrostomorpha and Lecithoepitheliata.
Like other flatworms in the order Polycladida, aside from the two stout tentacles on its head, this species has a remarkably flat, fragile, ovaloid body. As a cotylean flatworm, Praestheceraeus bellostriatus is brightly colored, though unlike its tropical relatives it inhabits relatively cold water.
There are at least 20,000 different species, but the main three types include flatworms, roundworms and segmented worms, according to Britannica. The earthworm, the worms you commonly see after it ...
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. [ 2 ] These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. [ 3 ]
Catenulida is an order of flatworms in the classical classification, or a class of flatworms in a phylogenetic approach. [2] They are relatively small free-living flatworms, inhabiting freshwater and marine environments. There are about 100 species described worldwide, but the simple anatomy makes species distinction problematic. [2]
