This is a summary of its classification until 2002 and they're still working on it.

The subphylum of a roundworm is Nematoda.
Mollusca is a phylum, not a subphylum.
The elephant seals belong to the subphylum Vertebrata, which includes animals with a backbone or spinal column. They are characterized by having a well-developed skeleton that supports and protects their body.

The oldest subphylum is likely the subphylum Vertebrata, which includes animals with a backbone, such as fish, amphibians, reptiles, birds, and mammals. Fossil evidence suggests that vertebrates appeared around 500 million years ago during the Cambrian period.
The subphylum of Apicomplexa is called Sporozoa. This group includes various parasitic protozoa that possess a unique organelle called an apicoplast, which is involved in various cellular processes. Members of this subphylum often have complex life cycles involving multiple hosts.
The subphylum of the koala is Vertebrata.
The elephant seals belong to the subphylum Vertebrata, which includes animals with a backbone or spinal column. They are characterized by having a well-developed skeleton that supports and protects their body.
