Why is this right?
Mammals stick their head out of water or they die. They have eyes to
see.
Dolphins see out of the water. Otherwise, they couldn't do all those
tricks.
Why wouldn't dolphins be aware of stars?
How do you know dolphins aren't aware of the stars?

They probably would not be because like most animals, they don't see objects
that are not moving....but I could be wrong about that.
As you probably know, humans developed the property know as 'rapid eye
movements' REM. Our eyes are constantly moving so we can see objects that are
at rest.

I told my cat he could use my telescope if he wanted to, but he said
he wasn't interested, it didn't smell right. He wants to see underwater
instead, he's been that way since he ate the goldfish. Dolphins are
different, they swim alongside the yacht because they confuse the
mast with a telescope and want to get a peek at stars in daylight.
Jumping out of the water to see nothing at night requires perfect
eyesight or they would not be able to do it.
I use a fish-eye lens in my front door to see visitors and stars.

I wonder if it's called a fish-eye because light refracts at the air-water
boundary and you get total internal reflections to which the eye of
the dolphin is adapted...

I'll tell ya, drosen is completely dead from the neck up if he imagines
a dolphin has a ghost of a chance of knowing anything about stars, no
matter how intelligent it is and he isn't.

Most mammals are aware of things that aren't moving. Anyone who
plays with a dog knows that the animals recognizes pthers, even when
they aren't moving.
I heard that frogs can only see something that is moving. The
neural circuits in their eyes subtract the stationary background.
Other animals use their sense of sight in producing camouflage.
Chameleons, flounder and octopuses change color to match their
stationary background. Octopuses even change shapes to match nearby
stationary objects. I don't think they could do this without
recognizing stationary objects.
Birds and crocodilians make nests out of sticks, stones and other
objects. I don't think they could do this without seeing things.

I don't know if this is the reason for our rapid eye movements. I
know that rapid eye movements have been studied for a few decades. I
never heard the conclusion that it is for seeing objects at rest.

I asked Androcles. He said that marine mammals aren't aware of
the stars. He gave no reason, but referred to them as being adapted to
their environment. I don't see how adapting to a marine environment
automatically means ignoring the stars, especially by creatures that
have to poke their head out of the water. He may be right, but I asked
him how he knew.

That's because it is bullshit that Henry made up.

There are eye movements that are indeed rapid (but not called REM .. that
refers to a stage of sleep where there is involuntary rapid eye moement)
that allow us to shift our gaze around a scene so we can take in the detail
... as we only have 'high definition' vision in a very narrow field of view
(the rest is low), so to get a detailed image, we need to keep moving our
eyes from point-of-interest to point-of-interest. There's also some less
rapid eye movements, such as tracking of moving objects, or adjusting the
eye when we change the angle of our head of body so that we can still focus
on a given part of a scene.

Androcles obviously communes with the sea creatures.
