The major similarity between unicellular and multicellular organisms is that both of them contain cell/cells. Unicellular organisms contain one cell and all of their functions are based on that one cell whereas multicellular organisms contain more than one cell and there functions are divided amongst different cells like nervous cells, cardiac muscle cells etc.
List of kennings. (Redirected from Whale-road) A kenning (Old Norse kenning[cÊ°ÉnËiÅÉ¡], Modern Icelandic [cÊ°ÉnËiÅk]) is a circumlocution (an ambiguous or roundabout figure of speech) used instead of an ordinary noun in Old Norse, Old English and later Icelandic poetry.

So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on.
