A dryad is a tree nymph, that is a female spirit of a tree, in Greek mythology. In Greek drys signifies "oak". Thus dryads are specifically the nymphs of oak trees, though the term has come to be used for all tree nymphs in general. They were normally considered to be very shy creatures, except around the goddess Artemis, who was known to be a friend to most nymphs.
The Phoenix, sometimes called a fenix or firebird, is a majestic, glorious bird with purple and gold plumage. Custom says that there is only one phoenix alive at a given time, but the fowl is so rare that no one has been able to corroborate this notion. They do not require food to sustain themselves, though they have been known to eat the gum of the frankincense tree.
Ichthyocentaurs- Greek myth: sea centaurs, having the upper body of men and the lower body of a horse but with a fish tail instead of hind legs. They were peaceful creatures but still retained some wild habits from their terrestrial cousins. They are the fastest sea creatures of the ocean.
