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]
Its body length is around 40 centimetres (16 in), including a tail length of 14 centimetres (5.5 in), and it weighs 1.5 kilograms (3.3 lb). It has a very prominent long nose and small pointed upright ears, a hunched-looking posture, a short tail, a rear-facing pouch, and three long, clawed toes on front feet.
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.
In addition to the behaviors indicating dominance, anoles may move their head up and down in a head-nod display (not to be confused with the head-bob display where entire frontal part of body is moved through "push-ups"), which is a submissive sign. [117] [119] [120] [121] Females maintain a feeding territory. Males maintain a larger breeding ...
Takydromus sexlineatus, the Asian grass lizard, six-striped long-tailed grass lizard, or long-tailed grass lizard, is an arboreal, diurnal species of lizard. The tail length is usually over three times the body (snout to vent) length in this species. [2] Males and females are similar, males being distinguishable by the presence of pre-anal pores.
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.
Echidnas are possibly named after Echidna, a creature from Greek mythology who was half-woman, half-snake, as the animal was perceived to have qualities of both mammals and reptiles. [citation needed] An alternative explanation is a confusion with Ancient Greek: ἐχῖνος, romanized: ekhînos, lit. 'hedgehog, sea urchin'. [5]
The southern red-backed vole or Gapper's red-backed vole (Clethrionomys gapperi) is a small slender vole found in Canada and the northern United States. It is closely related to the western red-backed vole ( Clethrionomys californius ), which lives to the south and west of its range and which is less red with a less sharply bicolored tail.
