Creatures of Planet Xepodium

Given that Planet Xepodium, had just recently formed few thousand years ago, as  time passes by, there are new life forms that evolve in the planet. These creatures are similar to what could be found on earth. The  creatures found on the planet our currently in their early prehistoric forms. Currently, there are only  land and aquatic creatures present on the planet. The  land and aquatic  creatures seem to share one common pattern, all of them consist of stripes. When observed one would not think noticing these stripes could be ignored, however the pattern of the stripes and colors, potray an important role.  This feature on the creatures skin, shows us what kind of threat they can be to each other as well as us. The deeper the shade of stripes can help us identofy, which region does the animal belong  from, the other commonality  that can be observed is that creatures roaming on land, seem to have gill like features that would give us the information that they could possibly stay under water for a little while.  

For example, a giant  sabertooth cat would have red straight sharp stripes,  and will usually  hunt with a pride of four.  They have gills to jump in the ocean and swim under water to hunt  big fish. but can only swim to a certain distance away from the land. The mammoth like creatures  would have more of a rounder  curve stripes that  would  give us an indication that they are  not aggressive but can attack if agitated. The aquatoc sea live is quite diverse here, however, it would be dangerous to travel too far away from the land, as there  humongous snake like aquatic creatures that  swims beneath the ocean. I would not know its exact color as it can only be recogonized by its shadows as it swims.
