ELI5 Why is beef the only staple meat with true intramuscular fat marbling?

Pork has a fat cap, poultry has subcutaneous fat, and seafood fat is oil that is dispersed through the meat. Why is beef the only one that we see the fat inside the muscle?

It isn't, you're just not looking at the right cuts of meat. Certain parts of a pig have marbling, certain parts of a cow don't, certain parts of fish do, etc, etc.  It just depends on the quality of your meat and which parts of the animal you're looking at.

A quick Google search of "marbled pork" or "marbled fish" or whatever will show you what they look like.
