If Dracula Was a Ferret

Giant River Otters have high metabolisms to generate heat underwater, hold their breath for up to 8 minutes but for a few while hunting, their nostrils and ears close so water doesn't waterlog them, scent mark with feces to communicate, short legs, float on their backs and hold hands while sleeping, can be found in groups of 10, have powerful bites and sharp teeth to eat, and long bodies and strong, flattened tails for swimming. All flora will get deforested, climate change makes Rainforests hot, and it’ll turn into a desert. Otters will become Vampire Ferrets through sucking blood for water. Becoming nocturnal to hunt prey and get away from the extreme desert heat and danger of the predators, have thicker and brighter fur to hunt more efficiently, burrow with specialized feet to wait for prey and feed on them, and become 2’ to run fast and need less food/water.
