Abstract The anemone Anthopleura xanthogrammica varies in color from
bright green to muddy brown. However, individuals found in caves
are white. White specimens of Anthopleura xanthogrammica collected
from dark caves along the Oregon coast were subjected to various
experiments to determine if these cave dwelling animals carried any
cells of the algal symbiont, and to ascertain whether adults could become
infected by feeding, injecting and placing in the surrounding
water algal cells which had been extracted from exposed anemones.
Fresh smears and prepared sections showed that the white anemones
were completely devoid of any algal cells and that adults of these
apparently were not susceptible to infection by cells removed from
naturally infected forms.
Algal cells extracted from exposed forms of A. xanthogrammica
were of two colors: green and brown. Two-dimensional paper
and thin layer chromatography with spectrophotometric analysis
proved that the green cells contained a complement of pigments
characteristic of and unique to green algae while the brown cells
contained a complement of pigments characteristic of and unique
to dinoflagellates.
