Jaguar in a marsh

The jaguar is a big cat that usually lives in jungles and near rivers and lakes hunting pretty much anything that moves, they have small nimble bodies to traverse the jungle while still being strong enough to hunt practically anything smaller than itself. The evolved jaguar would also most likely use that same mindset but it would also mainly eat fish since that would be the primary animal around. The jaguar has spots to hide in the jungle, the evolved jaguar would probably have stripes, not like that of a tiger but vertical stripes to hide in the tall marsh grass. Jaguars have faux eyes on the back of its ears to scare things away, the evolved jaguar would have markings like a crocodile on its back for camouflage while swimming, a wide tail like a beaver to propel itself in the water and wide feet for walking on mud.
