Gynandromorph
An organism that contains both male and female characteristics.
The term is mainly used in the field of entomology where butterflies occasionally occur displaying both male and female characteristics because of sexual dimorphism.
A gynandromorph can have bilateral asymmetry, one side female and one side male, or they can be mosaic, a case in which the two sexes aren’t defined as clearly (as in the calico lobster below).
As well as insects, cases of gynandromorphism have also been reported in crustaceans, especially lobsters, in birds and very occasionally in mammals.

Gynandromorph is derived from the Greek gyne female + andro male + morph form.
Note that gynandromorphism is different from hermaphroditism where only male and female reproductive organs are present as in, for example, some slugs and snails.
