Acipenseriformes
Acipenseriformes is an order of primitive ray-finned fishes that includes sturgeons and paddlefishes, known for their cartilaginous skeletons and importance in caviar production.
-
D.
Tetraodontiformes
Tetraodontiformes is an order of highly specialized ray-finned fishes that includes pufferfish, triggerfish, boxfish, and their relatives, many of which are known for their unique body shapes and defensive adaptations.
-

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Polypteriformes Description of subject: Polypteriformes is an ancient order of ray-finned fishes that includes bichirs and reedfish, known for their elongated bodies, ganoid scales, and ability to breathe air.
