When spotted hyenas were first discovered by explorers, they were thought to be hermaphrodites.
Early observations of spotted hyenas in the wild led researchers to believe that all spotted hyenas, male and female, were born with what appeared to be a penis.
The distribution of self-fertilization rates among animals is similar to that of plants, suggesting that similar processes are operating to direct the evolution of selfing in animals and plants.
which derives from Hermaphroditus (Ἑρμαφρόδιτος), the son of Hermes and Aphrodite in Greek mythology.
Arthropods are the phylum with the largest number of species.
For example, the great majority of tunicates, pulmonate snails, opisthobranch snails and slugs are hermaphrodites.Some people who are intersex, such as some of those with androgen insensitivity syndrome, outwardly appear completely female or male, frequently without realizing they are intersex.Other kinds of intersex conditions are identified immediately at birth because those with the condition have a sexual organ larger than a clitoris and smaller than a penis.According to Ovid, he fused with the nymph Salmacis resulting in one individual possessing physical traits of male and female sexes; Alexander ab Alexandro stated, using the term hermaphrodite, that the people who bore the sexes of both man and woman were regarded by the Athenians and the Romans as monsters, and thrown into the sea at Athens and into the Tiber at Rome.This contrasts simultaneous hermaphrodites, in which an individual may possess fully functional male and female genitalia.
Sequential hermaphroditism is common in fish (particularly teleost fish) and some jellyfish, many gastropods (such as the common slipper shell), and some flowering plants.
