A Cuvier’s Beaked Whale has shattered the record for the longest dive at 222mins, or nearly 4 hours. These marine mammals can also dive to the deepest depths, to nearly 3km.

3D-printing is helping to create artificial reefs around the world. Terracotta clay tiles shaped with coral geometry are placed on the sandy sea floor, creating a hard surface to support new coral growth. They’re more eco-friendly than concrete, requiring less energy to produce and naturally erode once the reef is established.
