The Coral Island
A small island in the northeast of the bay of bengal, about 9 km south of the Cox’s Bazar-Teknaf
peninsular tip and forming the southernmost part of Bangladesh. It is about 8 km west of the
northwest coast of Myanmar at the mouth of the river Naf.
There is a shallow lagoon in the middle of Uttarpara and it is connected to the sea during high
tide by a narrow channel on the western coast. The topsoil of Uttarpara consists of alluvial sands
mixed with shells of molluscs. There are two small dead lagoons and a stretch of marshy land in
Dakshinpara. Fish landing sites, bazars and schools are present only in Uttarpara.
Launches and country boats ply between the island and teknaf regularly. The population is about
3,700 and most of them are fishermen belonging to 535 families. One hundred eighty-two
species of wildlife are recorded from the island. Of these, 4 species are amphibians, 28 reptiles,
130 birds and 20 mammals. tourism to the northern part of the island exists during four months
(November to February). The most densely populated part is Jinjira. There is scarcity of sweet
water on the island. Only a few ponds and a number of tubewells supply sweet water for drinking
as well as for cultivation. Though the island falls in the monsoon zone, the climate is much
influenced by the sea. The main vegetation is coconut, betel nut and bamboo. Coconut trees are
abundant and more concentrated in the Jinjira area. The soil of the island is not so fertile. The
main agricultural products are onion, watermelon and some rice.
Several living small coral colonies are found in small sheltered pools very near the low tide level
around the island. They also occur in the surrounding shallow sea, mostly growing on the beach
rocks and calcareous sandstone concretions. The dead coral colonies also occur in pool-like
depressions within the high and low tide levels. Some of them are located at an elevation of
nearly 3.50m above the low tide level. The oldest fossil coral belongs to Late Pleistocene, giving
an age of 33,238 years (C14 dating). The clearest indication of the Holocene upliftment of the
island is the appearance of an emerged 3.0m coquina limestone cliff on the coast of Dakshinpara
ranging in age from 450 years at the base to 292 years at the top (C14 dating)
