Gene, 1992
A search for homeobox-containing genes was done in the genome of a primitive metazoan, the parasitic tapeworm Echinococcus granulosus. Five different homeoboxes were isolated, none of them belonging to the classical Antennapedia-type. Three of the homeodomains are similar to those from the Drosophila melanogaster NK-type genes.

Nature, 1963
ALTHOUGH the presence of haemoglobin in free-living flatworms (Turbellaria) has been recorded by several authors1–4, the pigment has not yet been investigated in detail. A large sample of the rhabdoccel. Phaenocora unipunctata (Orsted 1843), was obtained from mud from Coe Fen, Cambridge.

Muscling in on Parasitic Flatworms
Parasitology Today, 1998The musculature of parasitic platyhelminths (monogeneans, digeneans and cestodes) presents an attractive target for chemotherapeutic intervention in that it is central to locomotory movement and attachment and serves an essential role in alimentation (feeding, translocation of food and digestive waste) and reproduction (insemination, egg formation and ...

Tetrodotoxins in the flatworm Planocera multitentaculata
Toxicon, 2022The marine polyclad flatworm Planocera multitentaculata is known to possess high levels of tetrodotoxin (TTX), but the presence of TTX analogues in the species has been unexplored. In this study, TTX and several analogues such as 5,6,11-trideoxyTTX, monodeoxyTTXs, dideoxyTTXs, and 11-norTTX-6(S)-ol were identified in three adults and egg plates of P ...

Immunocytochemical localization of histamine in flatworms
Cell and Tissue Research, 1990Specific antibodies against histamine were used to demonstrate the occurrence and cellular distribution of histamine-like immunoreactivity in three species of flatworms (phylum Platyhelminthes). In the parasitic cestode Diphyllobothrium dendriticum, histamine-reactivity was found in neurons of the main nerve cords, and in cells lining the central and ...

Urceolarian Epizoites of Flatworms
Nature, 1947Peritrichs (Urceolaridae) living on the surface of flatworms seem to afford suitable material for a study of the population dynamics of the epizoic habit. The host is widespread, occurs in large numbers, and the smooth surface enables rapid estimation of the numbers of the epizoite.

Journal of Biological Education, 1980
A school project to investigate aggregations in flatworms is described. It was found by a series of simple experiments that the formation of aggregations in the flatworm, Polycelis nigra, was influenced by light intensity, temperature, and some form of chemical stimulus released by already aggregating flatworms.

Monogenean parasitic flatworms
Current BiologyVanhove and colleagues introduce monogenean parasitic flatworms, a species-rich group of ectoparasitic flatworms that are mostly found on the skin, gills, or fins of fish and have a life cycle involving a single host.
