Manatees are the gentle giants of the sea, spending their days mostly sleeping and eating — plants only, as these peaceful creatures are herbivores. They are friendly, and even use hugging and kissing body language to greet and communicate with each other. The friendly, docile beasts have no prey and bring no harm to any other creatures. This is perhaps why in West African tradition, manatees are considered sacred, and killing one requires atonement.
