Yes, infact, she can. I think it's because she grows gills, but it might be that mermaids can hold their breath longer than any animal! Mermaids (or mermen, or merchildre, etc.) are half-fish, half-human, so it could be either of them, although Emily's friend mentions gills a few times, so I think she has gills. If you'll notice, the first time she leaves Rainbow Rocks with Shone she is surprised that she swam that far with only one breath. Shona explains, saying simply, "We're mermaids." So, the simple answer to your question is 'Yes'.
Emily Windsnap is a 12 year old girl who lives in Australia. She is a fictional character. She turns into a mermaid when she enters the water.
No, they can't. Mermaids can be a human on land and a mermaid in water if one or their parents is a human, though, like Emily Windsnap. If you don't know who that is, read "The Tail of Emily Windsnap."
Unless you are referring to a fish or other aquatic animal named Emily, no.
