This is a sketch of a Kepler animal I've been working on. The idea for this life form is that they are adapted to drink methane through their straw like tongues and combust it within its shell to produce energy.

The shell on its back has these fins which help it absorb heat from the sun. It also has these pipes which expel excess smoke from the internal combustion.

The thing is with the life forms on Kepler is that they have adapted to behave like machines, their biology behaves similar to that of an engine running on gasoline. I guess overall im trying to make Kepler a place where nature resemble machines, and machines resemble nature.
