The scientific name for the Glaucus atlanticus is Glaucus atlanticus. It is commonly known as the blue dragon or sea swallow and is a species of small, blue sea slug.

From what I understand about arete...the concept of greatness in all things...the Trojan Glaucus and Diomedes of the Greeks are meant to exemplify heroism and humanity.

When the two meet on the battlefield, Glaucus tells the story about how he descends from Bellerophon. When Diomedes realizes that his grandfather Oeneus hosted Bellerophon, their forefathers are friends of old.

Diomedes and Glaucus must also be friends. (Another concept stemming from arete.) They exchange gifts and decide not to fight each other.

Papilio glaucus was created in 1758.

Conus glaucus was created in 1758.

Phyllobius glaucus was created in 1763.
