  "description": "A formidable silver hunter of the murky depths, the kob is instantly recognizable by its muscular, torpedo-shaped body, built for explosive bursts of speed. Typically encountered between 50 and 100 cm, trophy specimens can stretch well over a meter and tip the scales at more than 50 kilograms. Its distinctive features include a slightly protruding lower jaw, a series of small, sharp teeth, and a base coloration of silver to bronze that fades to a pearlescent white belly. A key identification mark, especially in the water, is the dark, smudged spot at the base of the pectoral fin. For the angler, a heavy headshake and bulldogging fight telegraph its identity long before it breaks the surface.",

      "description": "Young kob inhabit the shallow coastal nursery grounds, growing rapidly while learning to hunt small crustaceans and baitfish. This is a vulnerable period where they rely on shallow, murky estuaries and surf zones for protection from larger predators.",
      "appearance": "Body is slender and silvery with a distinct bronze-green iridescent sheen along the back. The classic dark pectoral fin spot is already present but often appears more defined and less 'smudged' than in adults. Fins are proportionally larger relative to body size. Typically ranges from 10 cm to 40 cm in length.",

      "habitat": "Shallow coastal waters, estuaries, tidal creeks, and sandy surf zones, often in brackish conditions.",
      "anglersNote": "Often caught by anglers fishing for smaller species, but important to release carefully as these are the future trophies.",

      "description": "The powerful, nomadic hunter, patrolling deeper reefs, shipwrecks, and offshore sandbanks in small shoals or as solitary ambush predators. This is the trophy phase, where the kob employs its explosive speed to chase down large baitfish and squid.",
      "appearance": "Robust, torpedo-shaped body with a powerful, slightly protruding lower jaw. Base coloration is a solid, polished silver to deep bronze on the back, fading sharply to a pearlescent white belly. The key identifying dark, smudged spot at the base of the pectoral fin is prominent. Fins are dark grey. Size typically ranges from 50 cm to over 150 cm, with large specimens developing a thick shoulder and deep body.",
      "triggers": "Reaching sexual maturity and moving from inshore nursery areas to deeper, open coastal and offshore habitats.",
      "habitat": "Coastal and offshore waters over sandy or muddy bottoms, near reefs, wrecks, and deep holes; commonly found from 20m to over 100m depth.",
      "anglersNote": "The premier target for trophy anglers, offering a brutal fight characterised by heavy headshakes and deep, powerful dives.",
