Tetrodotoxins Secretion and Voltage-Gated Sodium Channel Adaptation in the Ribbon Worm Kulikovia alborostrata (Takakura, 1898) (Nemertea) [PDF]

open access: yesToxins, 2021
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]

open access: yesMarine Drugs, 2020
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.

Investigating Non-Native Ribbon Worm Cephalothrix simula as a Potential Source of Tetrodotoxin in British Bivalve Shellfish [PDF]

open access: yesMarine Drugs
Tetrodotoxin (TTX) is a potent marine neurotoxin found in several phylogenetically diverse organisms, some of which are sought as seafood. Since 2015, TTX has been reported in bivalve shellfish from several estuarine locations along the Mediterranean and

Proteinaceous Toxins in the Mucus and Proboscis of the Ribbon Worm Cephalothrix cf. simula (Palaeonemertea: Nemertea) [PDF]

open access: yesToxins
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 ...

The accordion worm: a new genus and species of heteronemertean (Nemertea, Pilidiophora) from Galicia (Spain) [PDF]

open access: yesRoyal Society Open Science
Ribbon worms (Nemertea) are a less-known group of invertebrates, specially challenging for taxonomic studies due to the scarcity of external morphological features.

A hundred species, mostly new—first assessment of ribbon worm diversity and distribution in Oman [PDF]

open access: yesPeerJ
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]

open access: yesFrontiers in Neuroscience
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.
