Ursasuchus

Ursasuchus is a large predatory animal that evolved to be semi-aquatic with the size and strength of a bear, with the liftestyle of a hippo. Ursasuchus spends the day time in the water sleeping or hunting along the banks waiting for prey to wonder close enough for it to burst out of the water to grab with its proboscis and pull into it's jaws. when setting up an ambush it would darken its skin to blend in more easily underwater and at night when hunting on land, Once it attacks, it would immediately loose its camouflage, where it's skin would brighten up again. When eating, it would hold it's food with it's tusks and teeth-like structures in its lower jaws and the teeth in the upper jaws, while it's proboscis would feast on the food item in a manner similar to a mantis or cricket. It's lower jaw evolved from insect-like mandibles that slowly grew longer and developed "teeth". Eventually the mandibles merged and formed the Ursasuchus' lower jaw.

In the water, Ursasuchus would move around by walking underwater, using it's clawed front feet to pull and webbed back feet to push itself along the bottom. During the night, it will make its way onto land to hunt for any prey that may be wondering nearby. Once it has spotted prey it will use the darkness and it's darkening skin to sneak up on the prey and catch it by surprise, using it's strength and size to knock it down and maul it. When Ursasuchus would attack on land, it would charge after the prey in a short burst of speed, however it would frequently need to watch how much it uses up energy or else it would become too tired to fight it's prey to the ground. Once it has killed it's prey it will make it's way back to the water to consume it in peace.

During mating season, which would occur during the dry months, Ursasuchus would form harems in large bodies of water where one male would be dominant over multiple females that lack offspring. During this time, due to the amount of activity that would occur, prey would often avoid the area, making it harder to find food. Females (which are smaller than the males) would frequently have to wait til night time to go hunting for food. Males would have to stay in their territory in order to ensure no males come to claim his females, in which case males would frequently starve themselves to the point of becoming too weak to defend their females. If the male and females become desperate enough, they would resort to cannibalism where they would kill and eat weak females. On some occasions, the females would kill and eat the male if he is dying. Once the male is dead and no other males are nearby to take his place, the females would go their separate ways and find other harem groups with a male present. Whenever a rival male appears, the 2 Ursasuchus would first attempt to intimidate each other by displaying the purple bulges on their lower cheeks as well as use their natural color by constantly darkening and brightening their colors. If neither male backs down then they would immediately engage each other and fight. These fights would often lead to one of the males dying or to weak to survive any longer than a day. On rare occasions one male would grab the other male and lift them into the air, If the male that has been lifted submits, he will stop struggling and once he is let go he would be allowed to retreat. If he continues to struggle the male would clamp his jaws, impaling the struggling male with his tusks which would often kill them or leave them mortally wounded.

When the rain finally arrives, the male would breed with the females that are left and then they would separate and carry on with their solitary lifestyles. the pregnancy would take around 6 - 8 months, after which the female would give live-birth to 1-3 offspring who would depend on her for food and protection for 5 years. During their first year of life, they would drink milk from their mother using their proboscis which would lack teeth until they've become a year old. Upon reaching the age of 5 which would be their juvenile stage of life, they would be driven away by their mother and then left to fend for themselves. If the offspring continues to stay with their mother, she would most likely kill and eat them.
