I've heard on movies pirates say about whales 'she's gonna blow'.
But that doesn't necessarily mean the whale is female, right?
So, my question is: Does that apply here as well?
Hippos are strictly vegetarians. She hasn't come for a share of the spoils.
Why she intrudes in this way is a mystery. She is more powerful than the crocs
and her dominance over them is absolute.
We use 'they' when talking about a group of animals in general.

How 'she' came into use in the whaling business, I don't know.

Piratea are also prone to saying 'She's sinking', but that doesn't mean the ship is female. Emotion: stick out tongue

Students: We have free audio pronunciation exercises.
Wow, so it really is a female hippo then.
Thanks, Philip!
