Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Occurs in coastal waters and estuaries. Feeds mainly on invertebrates.

The flatmouth sea catfish (Plicofollis platystomus), also known as the flat-mouthed catfish or the flatmouth catfish, is a species of catfish in the family Ariidae. It was described by Francis Day in 1877, originally under the genus Arius. It inhabits estuaries and coastal marine waters in India, Myanmar, Bangladesh, Sri Lanka, and Pakistan. It dwells at a maximum depth of 50 m (160 ft). It reaches a maximum total length of 31 cm (12 in).

The diet of the flatmouth sea catfish consists of benthic invertebrates. It is considered an important foodfish, and its meat is marketed fresh. Due to a lack of known significant threats to its population, it is currently ranked as Least Concern by the IUCN redlist.
