It is said that the differences between male and female Seaden are how they tend to their flowers. The females make sure they get sun, and water them with their fountain like-tails. The males to not tend to their flowers, that is why it eventually dies, leaving only the spiked branches.
Female Seaden are not known to use the water spouts emerging from their tail offensively. Males, however, will not hesitate to attack you with a jet of water if you come too close.
Female Seaden tend to take better care of the flowers on their backs, while the males use the spikes from their dead flowers as a defense mechanism.
