Rescuers say six dolphins trapped in shallow waters near a community in northern New Brunswick are refusing to be guided out to sea.
Tonya Wimmer, of the Marine Animal Response Society, says they dolphins are "doing what they want to do."
Wimmer says their human helpers are regrouping in an attempt to figure out what to do.
It's been more than a week since seven dolphins became stranded near Lameque, with one dying two days later.
Three boats have made multiple attempts to herd the Atlantic white-sided dolphins, but the animals turn back before crossing out of the shallow water.
The rescuers say the biggest obstacle is the strong current, which gets stronger as the tide goes out.
Wimmer says the animals look in "fairly good health."
