👉 Acantholumpenus is a type of animal that has a single body segment, often referred to as an "apex," for its shape and size. It is characterized by its small size compared to other animals in the same family or genus, such as the canids (dogs, cats, etc.). Additionally, it lacks any appendages like tails, paws, or ears, making it a unique creature that is not typically found in their natural habitats.
