 The world heritage site,its enormous seagrass beds carpet the shallows, creating one of the richest marine environments on earth. Several hundred families of bottlenose dolphins live here, and one of the largest is called the Beachies. 

 
Puck began her family 15 years ago. Heavily pregnant, she's about to give birth to her eighth calf. With Puck today are two of her daughters,two granddaughters and her only son India. A five years old. He's still a bit of a mummy's boy and never far from her side. Janet Mann has been following the lives of the Bay's dolphins for 23 years.
 
"We have the entire Puck family. Puck is the one with all the speckles. In fact, she's due any day now. She's enormous."
 
Puck was the first dolphin that Janet got to know when she started her study. 
 
"Hey ,Puck. She's really quite extraordinary. She was just a yound animal back then. We know every calf she's had, every trial and tribulation she's endured. Oh, you're wide."
 
So much of what we understand about dolphin mothers and their calves comes from Janet's study. Now 33 years old, Puck is an old hand that being a mum. At the end of her year-long pregnancy,this would be her eighth and probably her last calf.
