Their most distinct
characteristic is a pair of bulging eyes. They spend most of their
time with their abdomen on the ground, so their natural enemies are
obviously from the sky. Their great bulging eyes are therefore their
protective talismans that help observing in advance. When they are
in danger, they jump away or make their way into the caves promptly.
They are amphibious, thus their damp skin are used for breathing.
Their pectoral fins enable them to move into the water when their
skin gets dry. They also make use of their pectoral fins while
fighting for territory.

They are originally found in South America, Africa and India. In
1949, Mr. Wu Chen-Hui and Mr. Kuo Chi-Chang brought them into Taiwan
to breed. Now they are found in most streams, rivers and ponds of
Taiwan.

They are found in the mangrove or river mouth. They are only found
in the wet and soft lands. They make great use of their pectoral
fins, which are also the things it shows to attract their mates.
