A landwhale is a humanoid organism weighing in excess of 300lbs (although smaller specimens have been reported). They are often seen in the company of other landwhales and humans. Interbreeding between landwhales and humans, although once thought impossible, has been know to occur and produce viable offspring in isolated cases. In fact, it is rumored that humans can turn in to landwhales if they do not follow a healthy diet and excersize regularly; this statement has yet to be confirmed by science. Genus: Homo, Species: cetaceous.
The landwhale attempted to climb the stairs, but had to stop on the 5th step due to heavy breathing.
