Physical Appearance
Phantoms have, like most of the Ghosts, a translucide body and depending on the specie of the deceased animal will be able to fly, float or only walk.
It has to be noted that Phantoms do not look like they did in their previous life. Indeed, Phantoms regress in evolution to look like another world's fauna that do not possess mana. More specifically they look like the animals of the Familiar dimension except with no Wiccans and no power.
Ecology
Wiccarium's fauna is different from the human world's since it is affected by mana, explaining why the fauna developed differently. For an unknown reason, when animals die their ghost seems to lose a great quantity of mana, causing a different evolution.
Animals based on the human world's animals will have their ghost return to the human world's animals shape. Animals created from mana or animals too much influenced by it will simply regress in their evolution. The last point especially concerns Draconis, Plantaes, Beasts: Orcus and Totoro, and Magic Beings.

Being Ghosts, Phantoms do not need to eat in order to survive. However, since Phantoms are not aware they are dead they tend to hunt for alive fauna but it's nerver quite successful not being able to interefere with the Real Dimension.

History
Many people discuss the realtion between Phantoms and Wiccan's familiars. Some people even think that Phantom may be the first stage of becoming a Familiar. Yet, many writings reject this hypothesis through the simple fact that Phantoms and Familiars comes from different dimensions, one being the Spirit Dimension and the other being the Familiar Dimension. Another fact that goes against this hypothesis is the extreme diversity of the Familiars while the rarity of the fauna isn't that balanced. Therefore, many consider this hypothesis as refuted.
