The other mammal, named Seebolit, is asleep more than it is awake, as it hibernates almost all standard year round, awakening for 4 or 5 days to copulate and eat an enormous share of fish from the sea (up to 2 metric tons a day). During their hibernation cycles they dig themselves into the ground near coastal cliffs, so deep that they surround themselves in a cocoon of water. Not as impressive of stature as the previous mammal, they are generally about 15 meters long and 5 around, with some rare cases being over 20 meters long and 8 around. A final word on these animals is that their dark blue (almost black skin, or perhaps the other way round) blends in so precisely with the cliffs that researchers have been found stepping an a flap or two and triggering a cacophonous reaction in which one of these animals growling sends the whole cliff into the same reaction.
