The right reply to the query: in line with this dichotomous key, any catfish should have, is D. a single dorsal fin, a small fin on the again close to the tail, and barbs close to the mouth. Clarification: To start with, on this dichotomous key we discover ourselves in key no 1 in possibility a, (has a single dorsal fin), this feature refers us to key quantity 5 a, (has small fin on again close to tail) that lastly leads us to key quantity 6, (has barbels close to the mouth) that permits us to establish the fish as a catfish. This small fin on the again, positioned between the dorsal fin and the caudal fin is named adipose fin. Then again, the barbels present in catfish are whisker-like sensory appendages close to to the mouth. Generally barbels are incorrectly known as barbs, that are present in fowl feathers for flight and symbolize a collection of branches fused to the rachis.
