How this entity was disambiguated
This entity first appeared as the object of triple T321214 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Actinopterygii
Actinopterygii is the diverse class of ray-finned fishes that comprises the vast majority of modern fish species found in marine and freshwater environments.
-
B.
Osteichthyes
Osteichthyes is a vast taxonomic group of bony fishes characterized by skeletons primarily composed of bone rather than cartilage, encompassing both ray-finned and lobe-finned fishes.
-
C.
Vertebrata
Vertebrata is a major subphylum of chordates comprising animals with backbones or spinal columns, including fishes, amphibians, reptiles, birds, and mammals.
-
D.
Cephalochordata
Cephalochordata is a subphylum of small, fish-like marine animals (such as lancelets) that retain a notochord throughout life and are important for understanding vertebrate evolution.
-
E.
Chordata
Chordata is a major animal phylum that includes all vertebrates and their closest invertebrate relatives, characterized by having a notochord at some stage of development.
- F. None of above. chosen

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: Neopterygii Description of subject: Neopterygii is a major clade of ray-finned fishes that includes most modern fish species, characterized by more advanced jaw mechanics and fin structures compared to more primitive actinopterygians.
