The kob is a large, silvery member of the drum family, with grey or brown fins and a dark blotch at the top of the pectoral base. It is a heavyweight predator that reaches around 70 kg, moving between estuaries, the surf zone and inshore reef.
Juveniles use estuaries as nurseries, while the big adults range along the open coast. It is one of South Africa's most important angling and food fishes.
