Alaria is a genus of flatworms, or trematodes, in the family Diplostomidae. Alaria is a genus of small parasitic worm about 2–6 mm long and approximately 2 mm wide. It is usually found in the small intestine of dogs, cats, or wild carnivores. It is most commonly found in Europe, Asia, and the Americas.
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.
Platyhelminthes (from the Greek πλατύ, platy, meaning "flat" and ἕλμινς (root: ἑλμινθ-), helminth-, meaning "worm") [4] is a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates commonly called flatworms or flat worms.
A pair of Taenia proglottids, dried and resembling sesame seeds, each containing hundreds of eggs Life cycle of T. saginata inside and outside of the human body. The life cycle begins with either the gravid proglottids or free eggs (embryophores) with oncospheres (also known as hexacanth embryos) being passed in the feces, which can last for days to months in the environment.
Dipylidium life cycle. Dipylidium caninum, also called the flea tapeworm, double-pored tapeworm, or cucumber tapeworm (in reference to the shape of its cucumber-seed-like proglottids, though these also resemble grains of rice or sesame seeds) is a cyclophyllid cestode that infects organisms afflicted with fleas and canine chewing lice, including dogs, cats, and sometimes human pet-owners ...
The Turbellaria are one of the traditional sub-divisions of the phylum Platyhelminthes (flatworms), and include all the sub-groups that are not exclusively parasitic.There are about 4,500 species, which range from 1 mm (0.039 in) to large freshwater forms more than 500 mm (20 in) long [3] or terrestrial species like Bipalium kewense which can reach 600 mm (24 in) in length.
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]
The "Platyzoa" / ˌ p l æ t ɪ ˈ z oʊ. ə / are a group of protostome unsegmented animals proposed by Thomas Cavalier-Smith in 1998.Cavalier-Smith included in Platyzoa the phylum Platyhelminthes (or flatworms), and a new phylum, the Acanthognatha, into which he gathered several previously described phyla of microscopic animals.
