Hypothetical / Re: False Monitor vs Cooper's Hawk
« on: October 28, 2018, 10:45:14 am »
Anyway, I back the Lizard.

Callopistes Maculatus, despite being much smaller, is avoided as prey from some of the Colubrids (which can grow up to 2m) they coexist with. When it comes to birds, they are not usually preyed upon, and when they are it is generally significantly less then other Lizards.

In this case, the False Monitor is slightly larger than the bird, with effective dentation and a fairly sturdy build. Considering how even its smaller relative is not preyed upon often, I think it speaks volumes on how dangerous they can be.

With Flavipunctatus, I have never heard of anything eating it at all. And they are sympatric with a number of carnivorans and birds.

False Monitor-Callopistes Flavipunctatus

Callopistes Flavipunctatus, commonly refered to as the False Monitor, is a large species of Teiid Lizard. It inhabits Northern Peru and Southern Ecuador, they are mostly found in dry forests, and hills. They are ground dwelling Lizards, and often make large burrows, one of the reasons they make burrows is to outlast unfavourable climates.

Callopistes Flavipunctatus is a large Teiid lizard, up to 1000mm in length, and weight in over 800 grams. The tail is two thirds of the length in these Lizards. The males of these Lizards are larger with larger heads in comparison to females. These lizards have a dark coloration. The Lizards often develope large jowels, similar to Tegus, they are also described as flighty and fast moving Lizards.

These Lizards have sharp and reccurved teeth, well suited to grasping large and active prey. Due to their muscular and expandable stomach, they are belived to have adaptations for large prey. These Lizards eat a variety of Animals, including Snakes, other Lizards, small Mammals such as Degus, and Birds. They have been known to eat Eggs and occasionally eat vegetation. They generally forage for prey, once spotted they ambush their prey, generally they kill their prey with one bite to the neck or a series of bites.



Cooper's Hawk-Accipiter cooperii

Cooper's hawk (Accipiter cooperii) is a medium-sized hawk native to the North American continent and found from Southern Canada to Northern Mexico. As in many birds of prey, the male is smaller than the female. The birds found east of the Mississippi River tend to be larger on average than the birds found to the west.

The average mass of an adult male ranges from 220 to 440 g (7.8 to 15.5 oz) with a length between 35 and 46 cm (14 and 18 in). The adult male is significantly smaller than the average female, which weighs 330 to 700 g (12 to 25 oz) and measures 42 to 50 cm (17 to 20 in) long. Its wingspan ranges from 62 to 94 cm (24 to 37 in). Individuals living in the eastern regions, where the sexes average 349 g (12.3 oz) and 566 g (20.0 oz), tend to be larger and heavier than those in the western regions, where the respective sexes average 280 g (9.9 oz) and 440 g (16 oz).

These birds capture prey from cover or while flying quickly through dense vegetation, relying almost totally on surprise. One study showed that this is a quite dangerous hunting style. More than 300 Cooper's hawk skeletons were investigated and 23% revealed healed fractures in the bones of the chest. Cooper's hawks prey almost exclusively on small to mid-sized birds. Typical prey species include American robins, other thrushes, jays, woodpeckers, European starlings, quail, icterids, cuckoos, pigeons and doves. Birds preyed on can range in size from wood-warblers to ostriches. They may also prey upon the raptor American kestrel and other smaller raptors, including their cousin the sharp-shinned hawk. They have been known to rob nests and may supplement their diet with small mammals such as chipmunks, hares, mice, squirrels, and bats. Even more rarely, they may prey on lizards, frogs, or snakes. It normally catches its prey with its feet and kills it by repeatedly squeezing it and holding it away from its body until it dies.

Post your favorite feats from Animals, whether it be intellect, speed, or conflicts/predation.

Hypothetical / Tiger Quoll vs Wildcat
« on: September 29, 2018, 11:47:10 am »
Wildcat-Felis silvestris

The wildcat is a species complex of small cats, comprising the European wildcat (Felis silvestris) and the African wildcat (F. lybica). The former is native to Europe and the Caucasus. The latter the ancestor of the domestic cat (F. catus) ranges through much of Africa; Southwest and Central Asia into India and western China.

Compared to other members of the Felinae, the wildcat is a small species, but is nonetheless larger than the housecat. The wildcat is similar in appearance to a striped tabby cat, but has relatively longer legs, a more robust build, and a greater cranial volume. The tail is long, and usually slightly exceeds one-half of the animal's body length. Its skull is more spherical in shape than that of the jungle and leopard cat. The ears are moderate in length, and broad at the base. The eyes are large, with vertical pupils, and yellowish-green irises. Its dentition is relatively smaller and weaker than the jungle cat's. The species size varies according to Bergmann's rule, with the largest specimens occurring in cool, northern areas of Europe (such as Scotland and Scandinavia) and of Middle Asia (such as Mongolia, Manchuria and Siberia). Males measure 43 to 91 cm (17 to 36 in) in body length, 23 to 40 cm (9.1 to 15.7 in) in tail length, and normally weigh 5 to 8 kg (11 to 18 lb). Females are slightly smaller, measuring 40 to 77 cm (16 to 30 in) in body length and 18 to 35 cm (7.1 to 13.8 in) in tail length, and weighing 3 to 5 kg (6.6 to 11.0 lb).



Tiger quoll-Dasyurus maculatus

The tiger quoll (Dasyurus maculatus), also known as the spotted-tail quoll, the spotted quoll, the spotted-tail dasyure or the tiger cat, is a carnivorous marsupial of the quoll genus Dasyurus native to Australia. With males and females weighing around 3.5 and 1.8 kg, respectively, it is mainland Australia's largest carnivorous marsupial, and the world's longest extant carnivorous marsupial (the biggest is the Tasmanian devil).

Tiger quolls live in a variety of habitats, but seem to prefer wet forests such as rainforests and closed eucalypt forest. They are arboreal, but only moderately, as 11% of their travelling is done above ground. Prey items eaten by quolls include insects, crayfish, lizards, snakes, birds, domestic poultry, small mammals, platypus, rabbits, arboreal possums, pademelons, small wallabies, and wombats. They may scavenge larger prey such as kangaroos, feral pigs, cattle, and dingoes. However, the tiger quoll does not scavenge as much as the Tasmanian devil. Much of the prey eaten by the quoll are arboreal. They can climb high into trees and make nocturnal hunts for possums and birds. The flexibility of their diets suggests their prey base is not detrimentally affected by bushfires. When hunting, a quoll stalks its prey, stopping only when its head is up. It then launches its attack, executing a killing bite to the base of the skull or top of the neck, depending on the size of the prey. The quoll will pin small prey down with its fore paws and then deliver the bite. With large prey, it jumps and latches on its back and bites the neck.

Discuss information on Reptile size.

Here is info on some of the largest of squamata ever documented in literature. The weights are scaled, but the actual lengths are found in data.
