Scenic has led one of the world’s first commercial night dives on a Scenic Eclipse cruise through Mexico and Costa Rica, bringing guests up close to a rarely seen occurrence in nature, the Diel Vertical Migration.
A dive in the onboard submarine, Scenic Neptune, gave guests a first-hand glimpse of the natural phenomenon, watching as millions of tiny, quarter-inch-long fish larvae ascended 1,000 feet – the equivalent of a human swimming 50 miles.
The migration is thought to be triggered by changes in the level of sunlight: as night falls, organisms swim upwards in search of food or to escape the clutches of predators in the depths of the ocean.
The dive took place off the shore of Huatulco in Mexico on October 5, 2022, during a 14-day Baja and Costa Rica Discovery sailing, part of Scenic Eclipse’s expedition cruise programme.

Scenic’s’ director of expedition operations Jason Flesher said: “We were given rare permission to undertake the night dive so wanted to push the boundaries and grab the opportunity to surprise and delight our guests.
“During the trip these animals pass through zones of ocean where the conditions are wildly different. At 1,000 feet, the water is roughly 4C, which is way colder than near the surface, and the pressure is about 460psi (pound per square inch), more than 30 times what it is up top.
“The fish travel up to eat – and to avoid being eaten. During the day vulnerable zooplankton hide from predators such as squid and fish in the dark depths. When night begins to fall, they rush to the surface to feed on the microscopic aquatic plants that live in the top few hundred feet of water – under the cover of night.
“On the dive, guests saw baby fish, lobsters and eels, all of which were just millimetres long. It was a truly amazing experience.
“This was the first-ever night dive in a submarine to take place in Huatulco and the first commercial night dive for any expedition ship. What makes these Scenic Eclipse Discovery Voyages so special is the fact that we offer guests the means to visit places that are typically inaccessible.”
