Genus of gastropods
Monotygma is a
genus of
sea snails ,
marine
gastropod
mollusks in the
family
Pyramidellidae , the pyrams and their allies.
[1]
[2] The status of this genus was for a long time confused, but the situation was clarified in a review by van Aartsen (1986).
Life habits
Little is known about the biology of the members of this genus. As is true of most members of the
Pyramidellidae
sensu lato , they are most likely to be
ectoparasites .
