The chameleon is among the most highly visually-oriented lizards, using this sense in prey capture, mating behavior, and predator avoidance. Unique features of chameleon vision include a negative lens, a positive cornea, and monocular focusing. The development of the chameleon visual system could have evolved to aid in prey capture and/or in predator avoidance. Chameleon eye The angle, or amplitude, of eye movement in chameleons is very large for a vertebrate and the eyes move independently of each other. This allows a chameleon to watch an approaching object while simultaneously scanning the rest of its environment. Chameleon eyes protrude laterally from the head, giving the lizard panoramic sight. An eyelid fused to the pupil protects the eyes, leaving only a small part exposed. With a negative (nearsighted or concave) lens and a positive (farsighted or convex) cornea, chameleons use a method of monocular focusing to judge distance called corneal accommodation. Each eye focuses independently, which is achieved by the chameleon eye’s unique anatomy of separated nodal and center points of the eye. Finally, “striated rather than smooth ciliary muscle in sauropsids” allows for rapid focusing.

The veiled is the newest species of chameleon to be introduced to Florida. None of the six chameleon species living in Florida is a natural inhabitant, but the veiled chameleon comes from the coastal regions of Saudi Arabia and Yemen. While little is known about the impact of the veiled chameleon on the Florida ecosystem, there is a possibility that due to competition of resources they may displace one of the other non-native chameleon species living in Florida. The bony protrusion from the top of its head separates it from the other species of chameleons living in the area.

COCKROACH Cockroaches are one of the most widespread and resilient creatures on this planet. They are practically everywhere around us, hiding in the walls, sewers, and perhaps your cupboard. They are also one of the most hated creatures by humans. If you are like most people, you will become determined to kill all of the roaches when you see them in your house. Despite such hatred towards them, how do cockroaches manage to thrive all around the globe?

In this video shows two giraffes using their six-foot necks as weapons. 2 Giraffes slam necks against each other until only one is left standing in this viral video. Necking occurs exclusively among males, and has little to do with impressing females. It establishes who among them will have the opportunity to mate with receptive females. It may take years for a young male to gain the respect of the dominant few, and some may never acquire it. Giraffe society is very loose, and varied. It is known as a "fission-fusion" social structure, where groups come together for periods of time, drift apart, and come together again. Males often travel alone, and tend to have larger territories than females. Females with youngsters, however, usually travel together for safety and convenience, and will take turns watching the babies as they play in little nursery groups called "creches" or "calving pools". Throughout their lives, males will engage in wrestling bouts known as "necking", where they will stand beside each other, swing their necks wildly, and batter each other with their heavy heads. The occicones are blunt, however, and these engagements aren't real fights, but rather measures of strength and fitness, that end when the weaker opponent concedes, and rarely result in injury. Often, rather, the combatants will engage in some close cuddling and mutual grooming afterwards, that sometimes even leads to sexual interaction. Female giraffes will usually come into estrus during the rainy season. They will pair up and mate with the dominant male of their choice. Males will taste the urine of females coming into season, and can determine their readiness to mate by this method

The Bengal tiger is a population of the Panthera tigris tigris subspecies. It ranks among the biggest wild cats alive today. It is considered to belong to the world's charismatic megafauna. The tiger is estimated to have been present in the Indian subcontinent since the Late Pleistocene, for about 12,000 to 16,500 years. Today, it is threatened by poaching, loss and fragmentation of habitat, and was estimated at comprising fewer than 2,500 wild individuals by 2011. None of the Tiger Conservation Landscapes within its range is considered large enough to support an effective population of more than 250 adult individuals. The Bengal tiger's historical range covered the Indus River valley until the early 19th century, almost all of India, Pakistan, southern Nepal, Bangladesh, Bhutan and southwestern China. Today, it inhabits India, Bangladesh, Nepal, Bhutan and southwestern China. India's tiger population was estimated at 2,603–3,346 individuals by 2018.Around 300–500 individuals are estimated in Bangladesh,355 in Nepal by 2022, and 90 individuals in Bhutan by 2015.

The Zanzibar red colobus is a species of red colobus monkey endemic to Unguja, the main island of the Zanzibar Archipelago, off the coast of Tanzania. It is also known as Kirk's red colobus after Sir John Kirk, the British Resident of Zanzibar who first brought it to the attention of zoological science. The Zanzibar red colobus, Piliocolobus kirkii, population on Zanzibar, represents a population of red colobus that is believed to have been isolated on the island after sea levels rose toward the end of the Pleistocene epoch. Furthermore, it is suggested through mitochondrial analysis, that phylogenetic groups within the red colobus have been genetically isolated from another since the Pliocene. This Old World monkey's coat ranges from dark red to black, accented with a black stripe along the shoulders and arms, and a pale underside. Its black face is crowned with long, white hair, and features a distinguishing pink mark on its lips and nose. Also, the Zanzibar red colobus has a long tail used only for balancing — it is not prehensile. Sexual dimorphism is generally decreased in the species, meaning the females have little difference in their body size and colours from their male counterparts. Females usually outnumber the males in their groups. The species has a notably small cranium and rotund body shape, with males potentially reaching over 12 kg and females, 10 kg. In adults, highly differentiated facial features help them to distinguish each other in a group.

Did you know that crocodiles have tough folds on the outside of their eyes? That's to keep their tears from flowing out.
