Varicorhinus alticorpus
(Oshima) |
| Common
name: |
She-mian, Mian-zi
(in Mandarin pronunciation), Tall-bodied ku fish |
|
| 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. |
