IN the crystal-clear waters of Hawaii, free diver Alegra Ally shared a swim and a play with another mum.

Pregnant with her first baby, Ally was able to get up close to a spinner dolphin and her newborn calf.

Her husband Erez Beatus, an underwater photographer and free diver himself, captured the stunning shots just off the shore of the Big Island, Hawaii.

“We always wanted to have this particular experience for Alegra to swim with marine mammals when she was pregnant”, said Beatus.

“The simple act of being in the water with them is quite amazing from a sound perspective. Babies can hear the dolphins through the womb and our baby was certainly very interactive during the dive.”

Beatus says there were about 60 to 70 dolphins including three mothers and their young.

Pods of spinner dolphins frequent the beaches in Hawaii and often come to nurse their babies.

“We went to swim in one of the bays and the dolphins came over so we started diving and swimming with them.”

He said the mother and baby left the pod and swam towards him and his wife.

“It was as if she was showing the baby to us. It was an incredible experience. “
