What is a sweat inlet?

Yes, in this book I have read that a hippo has pink sweat, but scientifically saying it I do not now.P.S. I read it in a Japanese book.

No. Even blood, which is the most potent carrier isn't harmful unless you've got a cut or otherwise get it into your system.

yes horses sweat. They sweat when they need to cool down just like humans. The sweat comes out of their pores.

It is an arm off of a larger body of water (often between rocky headlands).:)
