Many of these creatures later earned the interest of humans, be it for scientific reasons, out of prejudice, or from simple curiosity. Items useful for decorations and materials that did not exist in the human world (such as the liquid and blood from their internal organs) are of keen interest, especially for research for bio-weapons.
