00:00Ancient fish surviving millions of years now face modern threats.
00:05A sturgeon can glide through river water like a living fossil.
00:09Across rivers, lakes, wetlands, and coastal waters,
00:13ancient fish still carry armored bodies, strange mouths,
00:16and survival stories older than dinosaurs.
00:20The sturgeon swims along muddy river bottoms,
00:23using whisker-like barbels to search for clams, worms, and small prey.
00:27The paddlefish moves through large rivers with a long paddle-shaped snout
00:32that senses tiny food in the water.
00:35The gar floats near the surface with heavy scales, sharp teeth,
00:39and a long body built for ambush hunting.
00:41The bofin hides in weedy swamps and backwaters,
00:45breathing air when warm water holds too little oxygen.
00:48The kilocanth hovers in deep ocean caves,
00:52moving fleshy fins on a body once known mostly from fossils.
00:55The lungfish survives in shallow waters and muddy places,
01:00using air-breathing ability when conditions become harsh.
01:03These ancient fish now face dams, pollution, overfishing,
01:08warming water, and shrinking habitats that block old survival routes.
01:13A fish can survive asteroids, ice ages, and ancient seas,
01:17then struggle against nets, concrete, and dirty water.
01:21When a sturgeon rises beside a dam,
01:24deep time suddenly meets the modern world.
