Dragonfly vision is thought to be like slow motion for humans. Dragonflies see faster than humans do; they see around 200 images per second. [80] A dragonfly can see in 360 degrees, and nearly 80 per cent of the insect's brain is dedicated to its sight. [81]
Frogs are more often heard than seen, and other frogs (and researchers) rely on their calls to identify them. Depending on the region that the frog lives in, certain times of the year are better for breeding than others, and frogs may live away from the best breeding grounds when it is not the species’ mating season.
The origins of the word frog are uncertain and debated. [11] The word is first attested in Old English as frogga, but the usual Old English word for the frog was frosc (with variants such as frox and forsc), and it is agreed that the word frog is somehow related to this.
Tree frogs are arboreal, so the height of the tank is more important than the length. A variety of things for climbing, such as plants or branches, should be in the habitat. A shallow water dish should be included. Captive frogs should not be handled more than necessary; when necessary, clean gloves should be worn. [31]
Darwin's frog has undergone significant population declines due to habitat loss and degradation, largely from conversion of native forests to tree plantations. Since 2018, the species is classified as Endangered on the IUCN Red List. A 2013 study reported results of a population survey conducted from 2008–2012, which found the species at just ...
Red-eyed tree frog embryos use natural day and night light cycles as a signal for when to hatch, and tend to hatch just after nightfall. [27] Red-eyed tree frog eggs may hatch early (exhibiting phenotypic plasticity) when a change in the environment signals a danger to their survival. [28] Dragonflies, fish, and water beetles prey on the tadpoles.
The desert froglet, chirping froglet, or sparrow froglet (Crinia deserticola) is a species of frog in the family Myobatrachidae, endemic to Australia. Desert froglets occur mainly in dry or moist savanna habitats, principally from the mid-western border of Northern Territory, south-east into western Queensland and New South Wales and the north-east corner of South Australia.
The insect family Macromiidae contains the dragonfly species known as cruisers or skimmers.They tend to fly over bodies of water (and roads) straight down the middle. They are similar to Aeshnidae in size, but the eyes are green and just barely meet at the top of the head.
