there have been no confirmed discoveries of planets with known animal life beyond Earth. While astronomers have identified numerous exoplanets (planets outside our solar system), determining their habitability and the presence of alien life is an ongoing scientific endeavor.
However, it's important to note that the possibility of finding extraterrestrial life, including unique and potentially strange forms of life, remains a topic of great interest and active research. Scientists are continually searching for habitable exoplanets and studying their atmospheres for signs of life. Future discoveries may provide insights into the existence of diverse and unusual organisms elsewhere in the universe.
Until substantial evidence emerges, we can only speculate about the existence of strange animals on habitable exoplanets. Science fiction often explores imaginative possibilities, but it is crucial to differentiate between scientific knowledge and fictional concepts when discussing such topics.
