|
| Features: |
An
endemic freshwater fish to Taiwan, the adult Varicorhinus
alticorpus is tall and long, averaging 25-30cm in length but
capable of growing up to 50cm. Weighing roughly 0.6kg, their
bodies are flat, their bellies are round, and their heads
are small, short, round, and slightly humped on top. The Varicorhinus
alticorpus has a short, wide, and round mouth that stretches
downward and covers the upper lip. The mouth is horizontal
when closed and crescent-shaped when wide open, with the upper
jaw almost reaching the front edge of the fish's eye sockets.
Their lower jaw has a sharp cuticular layer and no barbels.
The eyes of the Varicorhinus alticorpus are quite small,
and the areas surrounding its pupils are silver in color.
The lower edges of their operculum, dorsal fin, pelvic fin,
and anal fin are all pink; the scales below their lateral
line sometimes have a rosy glow; their ray fin is grayish-black;
and their lower sides and belly are both silver colored. |
| Behavior: |
Varicorhinus
alticorpus feeds primarily on the aquatic algae clinging
to stones and aquatic insects. They grow to adulthood quite
fast and prefer to stay in rapid-flowing streams where the
water flow is abundant and the temperatures are lower. They
breed between July and October, at which time the females'
bellies will swell a bit while the males develop several large,
hard breeding tuberdes on the mouth. |
| Habitat: |
An endemic
freshwater fish to Taiwan, the Varicorhinus alticorpus
only appears in the streams of southern and eastern Taiwan,
such as the Kao-ping Stream, Hualien Stream, Pei-nan Stream,
and Hsiu-ku-luan Stream. |
