Cyclops is humanoid. He is an omnivore.

And after he had milked his cattle swiftly,
he again took hold of two of my men
and had them as his supper.
Then I went, with a tub of red wine,
to stand before the Cyclops, saying:
"A drop of wine after all this human meat,
so you can taste the delicious wine
that is stored in our ship, Cyclops."
He took the tub and emptied it.
He appreciated the priceless wine that much
that he promptly asked me for a second tub.

"Give it", he said, "and give me your name as well". ...
Thrice I filled the tub,
and after the wine had clouded his mind,
I said to him, in a tone as sweet as honey:
"You have asked my name, Cyclops? Well,
my name is very well known. I'll give it to you,

if you give me the gift you promised me as a guest. My name is Nobody. All call me thus:
my father and my mother and my friends."
Ruthlessly he answered to this:
"Nobody, I will eat you last of all;
your host of friends will completely precede you.
That will be my present to you, my friend."
And after these words he fell down backwards,
restrained by the all-restrainer Hupnos.
His monstrous neck slid into the dust;
the red wine squirted from his throat;
the drunk vomited lumps of human flesh.
