General description

Laevipeneroplis bradyi have planispiral tests with chambers that are partially evolute in early stages and later become flaring. Living specimens show a bright green colour due to chlorophycean endosymbionts.

General description

Early chambers are planispiral and involute, later ones are more or less flaring. Hallock and Peebles (1993) state that this species is morphologically very variable. Chlorophyte symbionts lead to a green colour in living specimens.
