All shrews are tiny, most no larger than a mouse. The largest species is the Asian house shrew (Suncus murinus) of tropical Asia, which is about 15 cm (6 in) long and weighs around 100 g (3 + 1 ⁄ 2 oz) [2] The Etruscan shrew (Suncus etruscus), at about 3.5 cm (1 + 3 ⁄ 8 in) and 1.8 grams (28 grains), is the smallest known living terrestrial mammal.

Envenomation of human beings is rare, as the location and structure of the blunt teeth, at the rear of the mouth, requires the snake to willingly grab-hold and "chew-in" its toxic saliva (something most people will ...

[5] It is only a small marsupial, with a body length between 34 and 38 cm (13–15 in), and a semi-prehensile tail length of 15 to 24 cm (5.9–9.4 in). [6]

The seven species of pademelons or scrub wallabies (genus Thylogale) of New Guinea, the Bismarck Archipelago, and Tasmania are small and stocky, with short hind limbs and pointed noses. The swamp wallaby (genus Wallabia ) is the only species in its genus.
The nose is short, yet it is pointy, and the eyes are relatively big. These mice also have a large infraorbital foramen . With the exception of the Aye-Aye , the meadow jumping mouse is the only mammal to have eighteen teeth with a dental formula of: 1/1, 0/0, 1/0, and 3/3.
South American coatis are diurnal animals, and live both on the ground and in trees. They are omnivorous but primarily eat fruit , invertebrates , other small animals, and bird eggs. Also, they search for fruit in trees high in the canopy and use their snouts to poke through crevices to find animal prey on the ground.
