A)Freshwater fish
B)Marine fish
C)Not a fish
D)Both (A) and (B)

Answer 1

The stinging catfish is capable of giving humans a painful sting. It has been recognised that poison from a gland on the pectoral fin spine is extremely painful.This species is 30 cm (12 in) TL long and constitutes a significant component of local commercial fisheries.

Complete answer:
Heteropneustes fossilis is an Asian stinging catfish, or fossil cat, found in India, Bangladesh, Pakistan, Nepal, Sri Lanka, Thailand, Myanmar, and Bhutan. In India, it is locally called kadu)or "karri" in the state of Kerala. In Assam, it is strongly favoured and known locally as singhi. This fish in Bangladesh is called Singi Mach. This fish is called hunga in Sri Lanka by the Sinhala-speaking culture.

H. fossilis is found primarily in wetlands, ditches, swamps and marshes, but also occurs in muddy rivers. It can withstand slightly brackish water. It's all omnivorous. This species breeds during the monsoon months in restricted waters, but when ample rain water accumulates, it can breed in wetlands, derelict ponds, and ditches. Due to its medical importance, it is in great demand.

Singhi is a highly priced freshwater fish and, due to its protein, iron and fat content, is recommended for convalescing individuals.Worms, crustaceans and small fish make up the diet of Heteropneustes fossilis living in the wild. They should be fed in captivity using frozen whole fish, such as white bait, lancetfish, etc. Live fish do not need to be used. Worms and insects were prepared, such as crickets. Pelleted food that is suitably sized will also be taken.

A spawning site is selected by both parents and their eggs are deposited on the substrate. When they become more autonomous, both parents will then guard the brood before the fry slowly moves away.

Hence, the correct answer is option (A)

Note: Stinging catfish or the scientific name of Singhi Heteropneustes fossilis, red-brown or brown-blackish in colour, slender flattened body with accessory air-breathing organs that can survive on low demand for oxygen and/or low water level in depth.
