Megophrys nasuta are light to dark brown on their dorsal surface with cryptic patterns resembling the forest leaf litter. They have two thin, ridged skin fold that run dorsal laterally across the animal's back. Coarsely granular skin with prominent tubercles on the dorsal surface provide further camouflage amongst the forest floor. They also have long, pointed dermal projections on the snout and upper eyelids that resemble horns and from which this frog gets its namesake.
On their ventral side they often have a dark chest and belly with a chin that ranges from a red to an orange coloring. On their chest is a single pair of tubercles. The limbs of Megophrys nasuta are light to dark brown with dark cross bars and their digits have blunt ends. They have no visible tympanum. The eyes are a golden brown complete with vertical pupil.
Megophrys nasuta males range from 70-105mm snout-vent length while females range from 90-125mm snout-vent length. Other than the slight difference in size there are no other sexual dimorphic traits. Behaviorally, however, Males however will “call” on the females in the evening (Bartlett, 1996).
Natural History:
Distribution/range
This species is known from Yala, southern Thailand (Taylor, 1962), throughout Peninsular Malaysia (Berry, 1975; Dring, 1979), Tioman Island, Singapore (Lim and Lim, 1992; Leong, 2000), Sumatra, Bintan, all parts of Borneo and the Natuna Islands. There are several stable populations within it's range countries. It is regularly encountered, and its characteristic call can be heard frequently heard in suitable habitats. It is, however, uncommon in Singapore (Lim and Lim, 1992).

Megophrys nasuta inhabits intact, lowland and submontane rainforest, typically in close vicinit...

...rom southern China, Indochina, Thailand and the Sundaland. By usng 2009 bp of sequence from the mitochondrial DNA genes 12S rRNA, tRNAval, and 16S rRNA the genealogical relationships were drawn amongst 30 named and unnamed taxa. Upon completion of the study it was further supported that the genus Leptobrachium was a monophyletic group which contained two major clades. One clade had three subclades primarily from disjunct regions including Borneo, Peninsular Malaysia and Java, and Thailand. Specifically, the Bornean subclade included one species each from the Philippines and Sumatra. The other major clade was further divided into two subclades, one from Indochina and the other from southern China (Vibrissaphora). The times of evolutionary divergence suggests a history which could not be explained by the geohistory of Southeast Asian major landmasses (Matsui, et al.).
The name ‘Liopleurodon’ is derived from Greek. It means “smooth-sided teeth”. The name was given by Henri Emile Sauvage. Sauvage gave this name because in 1873, he found the fossils of three teeth which were just 7 centimeter in length. The two species of Liopleurodon are L. ferox and L. pachydeirus Out of the two species, L. forex is quite known and famous. The fossils of both the species are found in the countries of England and France. L. pachydeirus is a very rare species as its fossils are not discovered in very good numbers. On the other hand, the fossils of L. ferox species are found in comparatively good number. The scientists have more knowledge about L. ferox because of the availability of the skeletons; some of which are more complete or less.
These moles are very distinctive and easily identified because of their noses. It has one of the most impressive nose in the animal kingdom which makes this strange-looking creature a lethal hunter. Around their noses they have twenty-two pink fleshy appendages which is used as a touch organ. The outer tentacles probe for a potential meal, then the inner sensors decide if the prey is edible. They are covered in thick, blackish-brown, water-repellent fur, and have large scaled feet and a long, thick tail. This animal is by far one of the most interesting animals in the world despite looking like a cross between a rat and an octopus. The way it behaves and utilizes its star nosed is fascinating and makes it very unique when compared to other
The face and front half of the hippopotamus body is gray, while in between its front feet and back feet it becomes turquoise. However, the back-left foot of the hippopotamus is partially turquoise and partially gray. The gray color of the hippopotamus is vibrant, meanwhile the turquoise part of the hippopotamus is muddled. It is muddled because of the black lines, which make the turquoise parts seem like a puzzle, for instance if one removes a piece of the hippopotamus’ midsection between his feet it can be easily be put back because of the black lines. Moreover, the lines on the hippopotamus’ face, the diamond shaped plants, and the hippopotamus’ eyes are also black. The texture of the hippopotamus seems smooth. Additionally, there seems to be a crack where the leaf is near the leg of the hippopotamus. Moreover, the crack shows that underneath the turquoise color is gray. Perhaps the hippopotamus was originally painted gray and then was painted turquoise. Additionally, the hippopotamus looks as though it is glowing because it is shiny. However, the turquoise part is not as shiny it is dull, perhaps because the turquoise color was painted on over the gray color. The color of the Model Hippopotamus is connected with the tone of the Model
Although the Hippocampus spp. are placed into the same class as other organisms more traditionally viewed as fish, their morphology bears distinct differences in comparison to other bony fish. The various species belonging under the genus Hippocampus range in maximum size from 20 mm to 300 mm(Foster 8). Their physical appearance is distinct from other members of its class due to their "horse-like head, monkey-like tail, and kangaroo-like pouch."( Lourie et al 12) Morphologically, seahorses do not have scales like traditional fish, but rather posses bony plates covered by skin. The appearance of bony extrusions and skin ...
The species A. afarensis is one of the better known australopithecines, with regards to the number of samples attributed to the species. From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor.
Furthermore, the grey squirrel’s color and size are distinctive traits that separate it from other species. First of all, coloring stays the same when it comes to males and females. Its hue ranges from pale grey to dark grey (Fischer, Lawinczak, Pagad). Its ears, underparts, and tail are all white to pale grey. Ginger-colored fur can be found on this squirrel’s head, hips, feet, and underparts (Lawiczak, Pagad). A natural occurrence among the grey squirrel is melanism, meaning it has an elevated amount of melanin in its pelt (Fischer, Lawinczak, Pa...
