Highly Toxic Ribbon Worm Cephalothrix simula Containing Tetrodotoxin in Hiroshima Bay, Hiroshima Prefecture, Japan [PDF]
In 1998, during a toxicological surveillance of various marine fouling organisms in Hiroshima Bay, Japan, specimens of the ribbon worm, Cephalothrix simula (Nemertea: Palaeonemertea) were found.

A hundred species, mostly new—first assessment of ribbon worm diversity and distribution in Oman [PDF]
Background Biodiversity is a key characteristic of any ecosystem but remains largely undescribed for most marine animals. Ribbon worms (phylum Nemertea), a diverse but poorly sampled phylum ubiquitous in the world’s oceans, are a case in point.

Comparative development of the serotonin- and FMRFamide-immunoreactive components of the nervous system in two distantly related ribbon worm species (Nemertea, Spiralia) [PDF]
IntroductionNeurodevelopment in larval stages of non-model organisms, with a focus on the serotonin- and FMRFamide-immunoreactive components, has been in the focus of research in the recent past.

Tetrodotoxins Secretion and Voltage-Gated Sodium Channel Adaptation in the Ribbon Worm Kulikovia alborostrata (Takakura, 1898) (Nemertea) [PDF]
Nemertea is a phylum of marine worms whose members bear various toxins, including tetrodotoxin (TTX) and its analogues. Despite the more than 30 years of studying TTXs in nemerteans, many questions regarding their functions and the mechanisms ensuring ...

Proteo-Transcriptomic Analysis Identifies Potential Novel Toxins Secreted by the Predatory, Prey-Piercing Ribbon Worm Amphiporus lactifloreus [PDF]
Nemerteans (ribbon worms) employ toxins to subdue their prey, but research thus far has focused on the small-molecule components of mucus secretions and few protein toxins have been characterized.

Proteinaceous Toxins in the Mucus and Proboscis of the Ribbon Worm Cephalothrix cf. simula (Palaeonemertea: Nemertea) [PDF]
Cephalothrix cf. simula is a highly toxic ribbon worm of the class Palaeonemertea, known for its high concentrations of tetrodotoxin. Recent transcriptomic and proteomic studies across Nemertea have revealed that species from all classes possess a ...

Gut Epithelium of the Highly Toxic Ribbon Worm Cephalothrix cf. simula (Palaeonemertea, Nemertea) Contains Tetrodotoxin-Positive Bacterial Endosymbionts [PDF]
Tetrodotoxin (TTX), widely known as pufferfish venom, is a low-molecular-weight guanidinium neurotoxin. It can accumulate to extremely high concentrations in certain animals, including pufferfish, blue-ringed octopuses, flatworms, and nemerteans. However,
