（单词翻译）
She's already lost four babies, at least one to sharks. This new calf1 would be especially precious. Very little is known about the first days of a calf's life. It's a rare opportunity for Janet to learn more.
"They are all very close, and they just sort of stay together, tight in rest"
All the dolphin families in Shark Bay are mostly made up of females. Just like cuddling in humans, the Beachies spent a lot of time
touching2 and patting. Family is everything for dolphins.
Son India swims alongside Puck. A five and a half years old,he's still unusually attached to her. Most young males leave the female families at around four years old, but India isn't in any hurry to go.
"He knows it's a big bad world out there with the big bad boys, so he's stayed close to mum for now. He's not gonna want to give all this nice family fun up, but he might have to."
With Puck's new baby due soon, India's days with the Beachies are numbered. Across the Bay, most of the females have already had their
calves3,
timing4 their arrival to well before the big sharks arrive.
