The clutch of remora fish are holding on tight, but collectively release their grip just as the humpback whale they are riding breaches the surface of the ocean. Moments later, everyone is back on board, as the whale re-enters the water, all hurtling together off the coast of south-east Queensland. This rare footage of suckerfish was captured by marine scientist Dr Olaf Meynecke from Griffith University using camera tags attached to humpback whales. The remora are able to sense the change in speed and water depth, he said. It was amazing to see how fast and nimble they were during several different rides with the whales.

Elysia chlorotica, the sea slug, performs a remarkable feat by eating algae and stealing chloroplasts, incorporating them into its own body to photosynthesize.
