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.
This snake is very slender, roughly 2 cm (0.79 in) thick, and may attain a total length of about 1.5–2 m (59–79 in). The tail is long and very delicate, but mostly used to hold on while reaching for prey. The head is aerodynamically shaped and very pointy, the mouth is very large and extends almost the whole length of the head.
The long-nosed potoroo exhibits many morphological specializations such as an elongated pointed rostral region (nose), erect ears, large eyes, claws for digging, and long robust hind legs. [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.
All coatis share a slender head with an elongated, flexible, slightly upturned nose, small ears, dark feet, and a long non-prehensile tail used for balance and signaling. Ring-tailed coatis have either a light brown or black coat, with a lighter underpart and a white-ringed tail in most cases.
The house mouse (Mus musculus) is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail.. It is one of the most abundant species of the genus M
The dentition is distinguished by sharp and strong canines, the broad permanent premolars are long and low with a profile that is serrated, concave, or horizontal at the cutting edge. An acutely pointed incisor extends from the long and narrow lower mandible. The dental formula of the genus is the same as other potoroid taxa: I3/1 C1/0 PM1/1 M4/4.
This animal has dark grey fur with lighter underparts, a pointed nose and a short, hairy tail. [7] It is about 15 centimeters (5.9 in) in length, including a 3-centimeter-long (1.2 in) tail, and weighs about 55 grams (1.9 oz). [7] Its front paws are broad and spade-shaped, specialized for digging. [8] It has 44 teeth.
