Tigerfish Hunting Behaviors and Biology

The video discusses how some fish, like tigerfish, have been documented eating birds, which is unusual for fish. Tigerfish in South Africa have been observed leaping from water to catch swallows, using two tactics: direct lunging and surface pursuit. The success of these tactics is influenced by the refraction of light, which distorts the fish's view of the birds. The tigerfish's adaptation to hunting birds is due to the lack of prey fish in their artificial lake habitat. However, this behavior may expose them to predation by other birds. The video concludes with a mention of Brilliant's courses on waves and light.

What is the usual way fish end up eating birds?

• By catching them accidentally
