In myths, Poseidon had children with many female humanoids, which resulted in many different types of children. They are not all considered demigods however, because a demigod is the child of a god and a human, which is why Heracles is one. Ursula is clearly a mermaid, meaning she is the child of a god and some other humanoid species that probably lives in the water. Therefore she is not a demigod.
