Toxicity of the flatworm Planocera multitentaculata at the adult and egg stages.

Sample	n	Body Weight (g)	Sample from:	TTX Concentration (μg/g)	TTX Amount (μg)
Adult	6	4.39 ± 0.92	Wild	115 ± 52 b	523 ± 285
Egg plate	3	N/A	Wild	23 ± 16 a	N/A
Egg plate	3	N/A	Aquarium	9328 ± 3356 a	N/A

Remaining fragments of egg plates were collected after feeding by the pufferfish Takifugu niphobles (at present Takifugu alboplumbeus). Data are shown as mean ± standard deviation. Different superscripts (^a and ^b) in TTX column indicate a significant difference among the measured values (Tukey–Kramer post-hoc test, p < 0.01).
