Filter feeding is among the most widespread dietary strategies in the world. From tiny bivalves to massive basking sharks, animals have developed a vast array of convergent strategies for filtering tiny food particles out of the water. This episode, we discuss what it takes to be a filter feeder, why it’s so common, the various methods animals employ to make it happen, and how we try (sometimes successfully) to identify filter feeding in the fossil record.
In the news: Thailand trilobites, mammal aging, bird-like footprints, and whale echolocation.
