Daphnia magna was chosen to determine
the critical concentrations of fluorides
because it is sensitive to pollutants,
it has a short life cycle, and is an
important fish food organism.

.

Daphnia’s transparency allows for the
observations of its inner anatomical
structures with the microscope.

Notice the immature young
moving in the brood pouch.

(There are numerous other posts
on Daphnia and fluorides.)
