Is a Cat’s Vision Good or Bad
A cat's visual sharpness is only about one-tenth of a human's - roughly 0.1-0.2, enough to make out objects around 10 meters away and blurry at that. The trade-off comes from the tapetum lucidum, a mirror-like layer that boosts dim light about 40 percent so cats see in one-sixth the light humans need, at the cost of clarity. Cats are nearsighted and built for the hunt: their best focus is about 75 cm, and they track moving prey (around 15-60 degrees per second, like a mouse) far better than still objects. They see blue-to-green but not red, and their wider 250-degree field of view beats our 200.
Cat Body Anatomy
Cats are born hunters with superior hearing, vision, and athletic ability. Let us explain a cat's body structure in detail.
Why Do Cats See So Well in the Dark?
A cat's night vision comes from a high density of rod cells, a mirror-like retina that amplifies dim light, and unusually large corneas and lenses set close to the retina. Together these let cats hunt and move in light far too faint for human eyes.
Understanding a Rabbit’s Physical Traits
Rabbits are built for alertness and quick escape. Their freely rotating ears carry dense blood vessels that release heat and give keen hearing, while eyes set on the sides of the head give a near 300-degree view, though daytime sight is weak. A constantly twitching nose reads scent, whiskers map nearby objects, and 28 ever-growing teeth demand constant chewing. Strong hind legs power leaps, a fragile skeleton needs careful handling, and body size ranges from under 2 kg to 8 kg across small, medium and large types.
Silver Celestial Eye Goldfish
The Silver Celestial Eye Goldfish is a variety of Dragon-back goldfish whose eyeballs protrude from the sockets and turn upward and forward toward the sky, hence the name sky-gazing eye. It is a relatively rare goldfish variety.
Chinese Tree Frog
A slender, bright-green arboreal frog from central and eastern China, built for life in the branches with sticky toe pads and a loud, repeated call.
Buff-striped Keelback
The Buff-striped Keelback (Amphiesma stolatum) is a small, non-venomous, diurnal snake reaching about 90 cm, with interlaced gray-brown and yellow-brown patterns. Gentle in temperament, its numbers have dropped sharply due to pesticide use.
Checkered Keelback
The Checkered Keelback (Xenochrophis piscator), known in Chinese as Yu You She (aliases Yu She, Cao Hua She), is a common, semi-aquatic, non-venomous snake across southern and eastern Asia. It is bold and readily strikes when threatened, so cautious handling is required despite its lack of venom.
Radiated Ratsnake
The Radiated Ratsnake (Coelognathus radiatus), also called the Tri-rope Beauty Snake, is a non-venomous colubrid from southern China and Southeast Asia. It is protected in China under the 'Three-Have' wildlife list and is best not taken from the wild.
African Lungfish
The African lungfish is a living fossil of a fish: besides gills, it breathes with a lung-like swim bladder and can bury into mud to aestivate through a six-month dry season. A carnivorous, mostly placid fish that grows up to 1–2 m, it is now threatened as its native African waters shrink.
