A group of scientists from UC Riverside confirmed the presence of Heterobilharzia americana — a flatworm known as liver fluke — along the banks of the Colorado River in Southern California.
A parasite that sickened 10 dogs and killed another in Southern California was found in the Colorado River in Blythe, its first known presence in the state. ... a flatworm commonly referred to as ...
The parasites, which can cause intestinal and eye problems, are now widespread in a nonnative snail in area lakes and reservoirs. The snails are also spreading across the U.S.
Sandcastle worms should not be confused with the similar, but more northern Sabellaria cementarium which are found from Alaska to southern California and have an amber-colored operculum. [4] Unlike P. californica, S. cementarium rarely forms colonies, does not settle gregariously, and its larvae do not respond to free fatty acids. [7]
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]
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.
The Polycladida [1] represents a highly diverse clade of free-living marine flatworms. They are known from the littoral to the sublittoral zone (extending to the deep hot vents), and many species are common from coral reefs. Only a few species are found in freshwater habitats.
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 ]
