If you are referring to mammals, the blue whale is the largest mammal.  The Blue Whale, Balaenoptera musculus, is also the largest mammal to have ever lived. In fact the Blue whale is the largest animal ever to have lived on the planet as far as we know; bigger by far than ever the largest Dinosaur. The longest Blue Whale ever measured was a female, 33.58 m or 110ft long. The heaviest weighed over 190 tonnes.\n\nThe largest animal on land at the moment on this planet is a mammal; the bull African Elephant. The largest specimen recorded stood around 3.96 m or 13ft at the shoulder and weighed over 12 tonnes.\n\nThe whale shark is a the biggest shark and the biggest fish. It is NOT a whale. It has a huge mouth which can be up to 4 feet (1.4 m) wide.

They are pretty much the same.   A stoat is also known as a Short-Tailed Weasel.  All weasels are in the same family (Mustelidae).

I would like to correct the other answer. MAMMALIA is the class of Marsupial Mammals. The Order of such mammals is MARSUPIALA. And I'm sure the phylum is CHORDATA.

The smallest species is probably the Dwarf Lantern shark {Etmopterus perryi), with total length of about 6 inches (16 centimetres) for mature males, and 7.5 inches (19 centimetres) for mature females. \nThe second smallest is the Spined Pygmy Shark (Squaliolus laticaudus), with 6 inches for males and slightly longer females (7.8 inches or 20 centimetres). \nAnother diminutive shark (although I'm not sure if it's the third smallest) is the Cookie-cutter shark (Isistius brasiliensis). It's bioluminiscent and grows up to about 1.5 feet (50 cm). \n\nAll belong to order Squaliformes, which includes the smallest sharks along with some good-sized species.\n\n----------------\nUpdate: I've learnt of another very small shark, Euprotomicrus bispinatus (22 cm total length for males, 27 cm for females). I guess that's the third smallest.

The whale. It is indeed a mammal.

An amoeba is the smallest animal in the world. It is a single cell organism. This means it has ONLY one cell in its whole body and insides.

As you've phrased it, the answer would have to be kittens.\n\nAre you sure you didn't mean "as dog is to PUPPY?"  In that case I think the answer is just baby monkey.

the largest living creature on Earth is the Blue Whale. Which incidentally is also the largest mammal

The smallest cell is a type of bacteria known as mycoplasma. Its diameter is 0.0001 mm. The smallest cell in the human body is the sperm cell.

Soricidae\n\nThis is a poisonous mammal which is related to the mole. It looks like a mouse and its body length is about 7-10 cm. It has a long tail, nearly 12 cm. The nasal part of its muzzle is filed off like a trunk. It has an underground, ground or amphibian way of life and feeds on insects, spiders, worms, snails, etc. It bears 3-8 babies in the spring and autumn. It is a very timid animal, with the exception of Blarina brevicauda, and one can meet it rarely.\n\nOnly the North American short-tailed Blarina brevicauda, the big European aquatic Neomys fodiens and the little European aquatic Neamys anomalus have proved poisonous. The poison is in the front teeth of the animal and flows out during biting. The poison causes paralysis and death to small mammals. In humans may occur a weak local inflammation on the site of the bite but there are no documented cases of death except in gypsy folklore.

Check out the Honey Badger, they are without doubt the hardest mammals on this planet. They were even listed in the guiness book of records as the most fearless. Check out the link.

Most walruses have 18 teeth.  We only see the two elongated tusks.
