Where
seen? These
small flashy fishes are commonly seen on many of our shores. They
are more active at night, when they are often seen swimming near the
surface in shallow waters.
What are silversides? Silversides belong to Family Atherinidae.
According to Fishbase:
The family has 25 genera and 165 species in tropical and temperate
waters. Most are marine although there are about 50 species confined
to freshwater and some can move from the sea into freshwater.
Features: 3-10cm long. These indeed silvery fishes are
small, slender and streamlined, with large eyes and relatively large
scales. They have small mouths that are upturned toward the water
surface. They have two widely separated dorsal fins. Often seen in
groups, sometimes in large schools. They are also called hardyheads.
What do they eat? Many feed on
zoo plankton or other tiny creatures that live in the water column
(as opposed to on the sea bottom).
Role in the habitat: They are
important prey for other larger fishes and sea birds.
Status and threats: Our silversides
are not listed among the threatened animals of Singapore. However,
like other creatures of the intertidal zone, they are affected by
human activities such as reclamation and pollution. Over-collection
can also have an impact on local populations and the other marinelife
that depend on them as prey. |
