Sea Secrets (4)16(4): 4. July-Aug. 1972.

–A reader reports observations of porpoises in the Loxahatchee River, Florida, throwing sea cows "halfway out of the water", and asks if this could be connected with the washing ashore of a dead manatee after one such incident. The answer notes that porpoises (i.e., bottlenosed dolphins) are playful enough to do this sort of thing, but suggests that the death might have had another cause.
