Quote from the Article:
Vincent tells of a pair of White’s seahorses she studied in Australia. The pregnant male was attacked during the night by another animal—probably a mollusk—that drilled a hole in his pouch and sucked out his brood. The seahorse was so badly injured Vincent did not expect him to survive. Yet his mate refused to abandon him, even though several unattached males tried to lure her away. Every morning she greeted her mate with the "dance" ritual that helps seahorse couples keep their reproductive cycles in sync. After several months, the male recovered and was able to father another brood. Says Vincent admiringly, "For any animal, that level of fidelity is extraordinary."
And there are humans using their dead bodies for decorations. Pathetic.
