An attempt is made to pay homage to the explorer, creating a heroic fiction around his death through metaphorical elements.
Thus, we observe our character absorbed in the examination of -as he resembles-, a novel animal species. That is nothing other than the biological lure of a monstrous abyssal creature in the action of devouring it.
The lure in the form of "sea wasp" represents: the mystery, the danger, the phantasmagoric and maybe also the door to another world.
The gigantic animal represents: La Parca, Abbaddon the destroyer, or the "Angel of the abyss", which stalks the character in his greatest and most terrible adventure: Death.
