The spider snail, Lambis, was sampled at Belle once be fore
Nectar and ten times after Nectar vith the results shoyn in
Pigure 21.
Each point is based on 1 to 4 (average 2.37
0.5)
samples. Liver, at > 1000 uc.”-*. was the most radioactive tissue
sampled, followed by gut, viscera. mass (not shown), mantle,
shell, and muscle. Visceral mass, collected 116 to 311 days
post-Nectar, was similar to gut in absolute level and in trend
over this period.

Absolute levels of snail tissues were higher than for clams.
Snail liver and clam visceral mass were highest of the invertevbrate tissues sampled.
Snail muscle was significantly higher
than clam muscle, but shells of snail and clam were about equal.
Pigure 22 and Table 15 show decay data for snails at Belle.
Curves 1 to 6 are pre-Nectar and are shown related to Mike,
November 1, 1952, as origin, which accounts for their steepness.
Other decays are related to Nectar.
Snail post-Nectar
decays almost equalled
the declines.
For liver
and shell the declines
were slightly steeper
than decays, while for
mantle, gut, and muscle
the declines and decays
were approximately equal.
