Fauna on Planet 4546B are unusual compared to fauna of Earth in many ways. Planet 4546B's ecosystem is dominated by vertebrates whilst vertebrates make up only a very small portion of life on Earth. Imbalances such as this and size disparity between predator and prey may be a result of the Kharaa bacterium.

All known fauna on 4546B possess yellow blood. On Earth yellow blood is seen in the sea cucumbers.


Reproduction

All known complex fauna on 4546B are simultaneous hermaphrodites, each individual capable of both laying eggs and fertilising eggs. Despite this, they are not asexual, as individuals do not fertilise their own eggs. Eggs are fertilised by another individual of the species.

Only one known species is an exception to this rule; the Sea Emperor Leviathan species is entirely asexual and does not require a mate, unlike other known species.
