Why did they go down there?
At sundown this world's atmosphere of air begins to cool at a faster rate than does a large body of water such as the sea. Might these amphibious life-stylists have plunged in and submerged for that reason, to mitigate a shift from warm to cold? In other words, was the action done to help regulate their body temperture ?
Or are creatures of that extraterrestrial species driven by an instinct at sundown? Are they seized with a bone-deep passion to return to the sea as darkness falls? And if so, then to do what? To hunt?
Did they hunt for prey animals?
Do members of this exotic alien species actually ever sleep?
Fish have a form of sleep. Dolphins and whales also sleep. Indeed in nature on Earth, among animals the phenomena of sleep -- from at least some partial kind all the way to complete slumber -- is widespread.
As a matter of fact, almost all animals sleep.
So it's an odds on bet that exterrestrials engage in sleeping -- no certainty, but a good bet.
Did these amphibious aliens go to sleep in the sea?

If so, where did they do it? Did they sleep suspended below the waves, rocking in the cradle of the tide? Or did they return to some vessel and sleep in their quarters within it?
Did they go on board a planetary 'splash-down vessel overnight? Certainly they had a craft of exquisite high tech capabilities somewhere... Was it waiting in the sea?
You don't have to be an exobiologist to picture the creatures swimming by night in the darkness, moving undersea in the currents and night-tides of salt water, intelligent animals submerged in the dark nocturnal depths.
oooooo
How do they find their way around down there in that black-out of an environment?
After sundown under the ocean's surface deep darkness sets the scene.
is a black realm where the only light may be an occassional glimmer of bioluminescence. faint glimmers of bio-luminescence from an oceaic menagerie of simple life forms
