Angel Fitor, a Spanish wildlife photographer, has been working long days to capture this unseen world. Fitor has a degree in marine biology, but he has spent most of his career as an artist, taking pictures of aquatic creatures from seahorses to sharks, usually while snorkeling or scuba diving. A few years ago, he grew curious about the organisms he couldn’t see, the tiny plankton that float with the ocean currents.
A recent study found that sharks visited urban areas due to easy access to food waste, leftover fish from a nearby aquarium being dumped into the ocean, and runoff creating bottom-up food webs.
Experts think that meadows of seagrass in particular helped ancient seahorses travel away from the waters of the Indonesian region (where they likely originated) and across the world.
