[Accumulation of tetrodotoxin from diet in two species of scavenging marine snails].

A feeding experiment of TTX-containing diet was conducted using the small scavenging marine snails Pliarcularia globosa and Reticunassa festiva. Seventy-five specimens of each species were divided into 15 groups of 5 individuals, of which 3 groups were directly submitted, without feeding, to toxin quantification as described below. TTX was not detected.

[Toxicity and toxin profile of scavenging and carnivorous gastropods from the coastal waters of Okinawa Prefecture, Japan].

From January to June 2009, a total of 64 gastropod specimens of 15 species were collected from the coastal waters of Okinawa Prefecture, Japan, and examined for toxicity by means of mouse bioassay. Among the specimens tested, 5 species, Nassarius glans, Nassariuscoronatus, Olivaannulata, Oliva concavospira and Zeuxis sp., were toxic.
