When compared to the other dolphin species, the Chinese White Dolphins are not the fastest swimmer; they can average about 4 kilometers per hour and travelling relatively short distances only. They tend to wander around when looking for food.

Dolphins, like humans, use their lungs to breathe and therefore need to swim to the surface at regular intervals. Yet, we do not know how deep they can dive. However, there is indication that the Chinese White Dolphins might be staying at the bottom of the sea. Researchers have seen large coatings of mud on the heads, dorsal fins and backs of these dolphins when resurfaced.

Other then swimming and diving, Dolphins also have different types of behavioral pattern. Below are some of the examples:

 

Spy-hopping: Dolphins bring just their heads right up above the water level and look around their surrounding; 

 

Splashing: Dolphins jump out of the water and then fall back on the surface. These actions create large splashes. Researchers believed the dolphins use this action to threaten the fish for their easy catching; 

 

Feeding Rush: Dolphins will suddenly charged directly towards their preys;

 

Fish Toss: Fish are thrown into the air by a flick of the dolphins' heads. 

There are a variety of ways the dolphins interact with each other and playtime is by far the most impressive display of natural behaviour. Body slamming is a jump, clear out of the water that eventually lands, slamming the surface of the water either on their backs or sides. This action can be used to confuse and stun fish, making them easier to be caught. It can also help to get rid of parasites on their skin.

Bowing or a jump clear out of the water (often seen in other dolphin species riding the bow waves of boats and ships) is a way to observe the surrounding environment and take a good look around. Games are also played when feeding. Dolphins will sprint towards their prey in a great feeding rush which catches the fish unawarely. Once caught, dolphins will sometime play with their food, flick their heads and throw the fish around.

As highly sociable mammals it seems surprising when, according to a variety of surveys, male dolphins live solitary lives. Females, on the other hand, live together in 'nurseries', taking turns to search for food and look after the calves. According to research, it is more common for these dolphins to give birth to calves between Spring and Summer.

Calves can be easily recognised because of their distinctive dark grey colour and their floppy dorsal fins. In September 2001, the foster parents of the EPSON Adopt-A-Dolphin Programme witnessed a female dolphin giving birth to a calf. It was named Sunny, hoping it can lead a sunny and healthy life here in Hong Kong's murky and polluted waters.

It is rare for researchers to witness sexual activities of male and female dolphins in the wild. The act itself is brief amongst dolphins and by mating stomach to stomach it's difficult to observe. Often mating will take place after a certain amount of games involving chasing and when the dolphins become increasingly vocal by clicking and whistling.
