On Friday 24th we were in the aquarium and of all the animals those that mas I liked they are the  Beluga Whale, and Pacific White-sided Dolphins  

Beluga Whale
A beluga’s mouth is permanently upturned like a smile. It’s easy to connect with these sociable whales as they glide by in their Abbott Oceanarium habitat: They might turn a curious gaze your way, crinkle their melons (foreheads) and whistle—or even spit a stream of water! The fact that these interactions are natural behaviors only makes the experience more fun.

The majority of belugas live in the arctic and the seas and coasts around North America, Russia and Greenland; their worldwide population is thought to number around 150,000 individuals. They are migratory and the majority of groups spend the winter around the arctic ice cap; but when the sea ice melts in summer, they move to warmer river estuaries and coastal areas. Some populations are sedentary and do not migrate over great distances during the year.

Pacific White-sided Dolphins 

Pacific white-sided dolphins are found in temperate waters of the North Pacific. They inhabit waters from the continental shelf to the deep open ocean.Like belugas, dolphins use echolocation to navigate and to find food in murky waters. They send out high-frequency clicks that rebound off objects. The dolphin’s forehead and lower jaw pick up the returning sound waves, enabling it to interpret an object’s distance, size and shape.

   

Dolphins lack vocal cords. Muscles inside the blowhole produce the squeaks, moans, warbles and other sounds that you can hear our dolphins demonstrate. And each dolphin has a distinct whistle to identify itself, much like a name. But this chorus of sounds is not merrymaking. It’s communication. The vocalizations, as well as such behaviors as tail slapping, biting, or rubbing, may be a means of keeping track of one another, courtship, or alerting others to danger. Researchers are trying to translate the gestures. Whether humans ever crack the code, dolphins’ complex language points to their intelligence. The next time you visit Shedd Aquarium, listen for the distinctive sounds each dolphin makes.      

had many varieties of fish, it is a very beautiful place, it takes time to appreciate each of the species found there.
