01. Rising Knife Violence Alarms Britain

Swimming hundreds of feet beneath the ocean’s surface in many parts of the world are prolific architects called giant larvaceans.
These zooplankton are not particularly giant themselves (they resemble tadpoles and are about the size of a pinkie finger), but every day, they construct one or more spacious houses” that can exceed three feet in length. The houses are transparent mucus structures that encase the creatures inside. Giant larvaceans beat their tails to pump seawater through these structures, which filter tiny bits of dead or drifting organic matter for the animals to eat. When their filters get clogged, the larvaceans abandon ship and construct a new house. Laden with debris from the water column, old houses rapidly sink to the seafloor.
