"Sea Monster" washes up in China - What is this thing?

Just not a very good one.

If so, they should look for its companion Sea Squirrel.

If it’s a whale, why does it have fur?

You’re talking about people who described gaping fissures in rotting flesh as “orange stripes”. The “hair” is probably strands of decaying tissue–assuming there’s anything hairlike present at all; there’s no sign of hair or fur that I could see in the pictures.
