Forever
Dolphins can stay with their mothers for a few months or they will stay with them for a few years, depending on how close it is to its mother.
Baby dolphins stay with their mother for 3-4 years.
yes dolphins can stay up long because they are like mamals
Young dolphins stay with their mother until they are five to six years old.
about 25 years
about 2-3 years
If you mean how long can dolphin stay under water, it's about 20 minutes for a common bottlenose dolphin. I am not sure about other species of dolphins.
about 4 years
As a rule, young fish do not stay with their parents at all, but fend for themselves as soon as the fish eggs are hatched. Marine creatures that care for their young and keep them with them for an extended period are mostly not fish but marine mammals like whales, dolphins and orcas.
