As a result they become targets for a whole group of predators – birds, larger fish, sharks, whales and dolphins – all join in the feeding frenzy.

What are five predators of sardines?
These predators include dolphins, whales, sharks, seals, penguins and various seabird species such as Cape gannets and Cape cormorants. However, depending on environmental factors, there are different variants in the Sardine Run's usual scenario.

Sardines form a tight ball to protect themselves against potential predators, which – in our exhibit – include yellowtail, dusky kob and leervis. When larger fish approach the shoal, the silvery fish move in the opposite direction in a single ribbon-like motion.

Where do sardines lay eggs?
Sardines are migratory species; they migrate to specialized grounds for spawning and migrate back to their usual grounds after spawning (van der Lingen et al. 2010). Spawning is the process of releasing gametes (sperm and/or egg) into the water column.

What kind of birds eat sardines?
Sea Birds and Penguins
Sardines often swim at or near the surface, especially if they're trying to escape underwater predators. This is a cue for sea birds to dive in and grab a meal, and terns, gannets and brown pelicans are quick to take advantage of the situation.

What fish escapes predators between rocks?
Scorpionfish are exceptional sit-and-wait predators. Scorpionfish only hunt at night and spend daylight hours resting in crevices. They will remain in the shadows of rocks or reefs before pouncing on unsuspecting prey swimming by. Their diet consists of small fish, crustaceans and snails that also live in coral reefs.
