Ruby seadragon also have prehensile tails, while leafy seadragons and weedy seadragons lack these tails. [10] One explanation is that this absence in the leafy weedy seadragons evolved in each species independently, and that the prehensile tail in the ruby seadragon was maintained from a common ancestor of Syngnathidae.

A vanishing puzzle is a mechanical optical illusion showing different numbers of a certain object when parts of the puzzle are moved around.

It depicts two arrangements made of similar shapes in slightly different configurations.
