Question

What's the difference ?
There are two sentences :

A. The ocean is home to all these animals.

B.The ocean is the home of all these animals.

Sentence A is from a book , I would like to know if sentence B is correct and what's the difference , thank you so much.

Answer

Think of the first expression as idiomatic.  It is expressive - the animals feel comfortable in the ocean.  If you have just managed to buy a very small, simple flat in downtown Shanghai to live in, you might say:

"This flat/apartment may not be very big or luxurious, but to me, it's home."

The second sentence is correct but does not feel as natural as the first. As a neutral statement, you could say:

"All these animals live in the ocean," or more scientifically, 
"The ocean is the natural habitat for all these animals."
