Popular Fishes and Marine Mammals in KAIYUKAN
Sea Otter SEA OTTER

There is no argument about who is the No.1 gourmet in the KAIYUKAN Aquarium. It is a sea otter. They enjoy a wide variety of delicacies such as squids, horse mackerels, salmons, cods, clams and crabs. They have big appetite, and they exercise more actively than many other creatures. They also enjoy a kind of mischief.
As their bodies are covered with 0.8 to 1.0 billions of hair, you do not need to worry about them living in the cold climate around Aleutian Islands. Observed closely, sea otters in KAIYUKAN show their characteristic faces featuring surprised eyes, white eyelids and long eyebrows. Like human beings, their characters and preferences for foods are quite diversified.

King penguins, gentoo penguins and rockhopper penguins are displayed in KAIYUKAN. You can easily distinguish their differences by their figures, as well as their feet colors. King penguins have black feet while gentoo penguins have yellow feet and rockhopper penguins' feet are pink.
Their characters are also different. King penguins and gentoo penguins have rather mild characters. On the other hand, rockhopper penguins show an aggressive nature, featuring red eyes and decorative yellow feathers. Being fond of fights, they may tend to fight even with human beings. So, watch out not to fight with them.
Penguins are monogamists. Like human beings, they select their own partners. They sometimes divorce or get remarried.

Japanese name "Kama (means sickle) Iruka (means dolphin)" was named after their white dorsal fins being similar to the sickle shape. The Pacific whitesided dolphins at KAIYUKAN have beautiful dorsal fins.
Their names such as Crew and Aqua are all related to the sea. They are fond of playing around and extremely talented in creating pleasures. For instance, they play with and eat bubbles that come out of their own nostrils.
The Pacific whitesided dolphins have mysterious abilities to quickly recognize directions and measure distances by sounds. This special ability allows them to swim at super high speed under the water.

Three babies of harbor seals were born in KAIYUKAN. White fur covers them when they are born. The fur color turns cream as they grow up. Those babies were all sons, named Chichi, Toto and Pearl. Ms. Yumi Morishita, a popular Japanese cartoonist, gave them these names.
