A total of 119 specimens of th exanthid crab Zosimus aeneus were collected from Ishigaki Island (102), Hachijo Island (1), the Bonin Islands (5), and Ceby island in th ePhilippines (11) from 1979 through 1982, and asayed for toxicity by mouse asaay.
The results showed that almost all the speciment were toxic, except a single specimen from Ishigaki Island. A remarkable individual variation of toxicity was observed among th especimens collected form a given locality, even mong those from a narrow area. The local variation in toxicity was also large. Ishigaki specmens generally showed higher toxicity scores than those from other localities, the highest score rcorded being 16500 MU/g.
There was a tendency that the toxicity is higher in specimens less than 60g in body weight than in larger ones. No significant differences in toxicity were observed between sexes and between years of collection.
