Fig 1.
Clearance rate of Mytilus edulis exposed to Karlodinium armiger and Rhodomonas salina.
The mussels were exposed to a low and high bio-volume equivalent concentration of each algal species. Data presented as mean values with SE bars.
Fig 2.
Mortality of Mytilus edulis exposed to six Karlodinium armiger concentrations for 24 and 48 h.
LC50 values of 9.4·103 ± 2.7·103 cells ml-1 and 6.1·103 ± 0.3 ·103 cells ml-1 were found after 24 and 48 h, respectively. Data presented as mean values with SE bars.

Karlodinium armiger tube feeding on Mytilus edulis embryos and trochophore larvae.
Initial tube feeding by K. armiger on a mussel embryo (A). Karlodinium armiger cells attached to a mussel embryo causing the vitelline coat to disrupt and release of egg content (B). Karlodinium armiger attracted to egg content released from a disrupted embryos (C). Karlodinium armiger tube feeding on a mussel trochophore larva (D).

Mortality of Mytuilus edulis embryos and trochophore larvae after exposure to Karlodinium armiger at four different concentrations.
Mortalities of embryos and trochophore larvae, separately and when pooled as a function of K. armiger cell concentrations. Data presented as mean values with SE bars.
