And what do elephant seals in heat sound like?
A great undulating belch.
I learned this while reading a story about elephant seals and how Lady Clairol helped students bleach the fur for identification purposes:
"We used to have contests at night to see who could most realistically imitate the normal and special mating calls of sea lions and elephant seals. The best way to perform the mating roar of a bull elephant seal was to drink 3-6 cans of beer real fast (any carbonated beverage would do though) and then urp up all the C02 in one long belch, modulated by the larynx. Dorm Seven sounded really strange at night during the elephant seal mating season."

Look, people change at night. They become all kinds of things: werewolves, vampires, zombies, alcoholics... (same difference). I just prefer the elephant seal.
