Did you know that caterpillars have a unique feature called "stemmata" or "ocelli" that function as simple eyes?
These light-sensitive cells differ from the compound eyes found in adult insects on the sides of the Caterpillar's head in pairs. The number of ocelli can vary from species to species, with most having six arranged in three pairs.
However, some caterpillars may have fewer or additional ocelli. Despite their small size, these ocelli play an essential role in helping caterpillars detect changes in light intensity and navigate their environment, especially during low-light conditions.

Mothers carry their babies in utero for a 17-month gestation period, and they give birth every three to 10 years until becoming menopausal around age 40. They are exceptionally protective of their offspring, and often adolescent females are recruited to assist in caring for calves. Mothers will nurse their babies for up to two years, forming a bond so strong that if a mother dies, the mortality rate of her sons increases. Orcas are some of the affected mammals in the ocean due to pollution, and the contaminants make their way into breastmilk, increasing the mortality rate of all young to 50% within the first year.
Killer whales hunt in pods, similar to a wolf pack, which is how they earned the moniker "wolves of the sea." A pod is a family group of up to 40 individual orcas and they prey on a variety on animals, using different techniques to capture them. While resident pods will focus on fish, transient pods are typically on the hunt for larger marine mammals.
Orcas work cooperatively to herd fish into a compact area where they're easier to consume. If they're after penguins, sea lions, or other animals on the surface, the killer whales will slap their tails on the water, creating a large wave that sends their prey off ice floes and within reach. Pods of orcas can take down something as large as a blue whale by surrounding it, then chasing and biting at the mammal until it weakens enough to be ripped apart and eaten.
As social creatures, orcas value sharing their hunt and females will share all the fish they catch with their offspring. Males, however, will only give away about 15% of their catch, typically shared with their mothers.
The orca is an apex predator, meaning it's at the top of its food chain and has no immediate threat as one of the largest and most powerful aquatic animals. However, the species is still threatened by environmental concerns, such as fishing equipment discarded or lost at sea like nets that pose entanglement dangers, chemicals that don't break down in nature and become stored in the fatty tissue of the orcas when they digest contaminated food, and shock waves from underwater explosives or military sonar that can cause orca blood vessels to burst and hemorrhage.
As social animals, orcas rely on a system of communication tools to talk with members of their pods, navigate the ocean, and hunt. On the surface, they use body language like breaching, slapping their flippers or tail, or bringing their head out of the water. Each population of killer whales has its own unique language, developed over millions of years, and made up of a series of whistles, clicks, pulsed calls, low-frequency pops, and jaw claps made by forcing air through the nasal passages and amplifying the sound through the fatty area of their heads, commonly referred to as the melon. When receiving sound, the orca uses its jaw - sound waves from echolocution travel from the jaw to the inner ear and then to the brain, where a detailed image is created. Their echolocution is considered the most powerful and most sophisticated of any animal.
The environment ministry offered amnesty to Indians holding undocumented exotic animals as a first step towards regulating their trade, as part of a larger effort to assess various risks of animal-to-human transmission of disease. Conservationists have welcomed the move, but say India must strengthen its laws and improve their enforcement.

Delhi: Kangaroos. Lemurs. Rhinoceros iguanas. The native habitats of these wild animals lie thousands of miles away from India, in Australia, Africa and the Americas, respectively. All of these and other exotic bird, reptile, amphibian and mammalian species, including critically endangered ones, are in the possession of private individuals in India, according to Ministry of Environment, Forest and Climate Change (MoEF&CC) data accessed by IndiaSpend.

Good Boys is a raunch-filled, F-bomb-laden, almost-coming-of-age comedy directed by Gene Stupnitsky and produced by (shocker) Seth Rogen.

Since American Pie reconfigured Porky's 20 years ago, the modern sex comedy has abided by a tacit formula. Call it the sweetness-to-raunch ratio. It would be completely unacceptable for comedies about woefully inexperienced dudes to be only about their single-minded pursuit of gratification, so it has to be cut with material about friendship or the tender feelings they can access in vulnerable moments. And age is the key factor: the younger the dudes, the more sweetness required. The 40-Year-Old Virgin can be as raunchy as it likes, but the STR ratio changes with American Pie and Superbad, which have many more scenes of teenage boys bonding over their shared ineptitude or treating girls with kindness when no one is looking.
So what to do with sixth-graders?
The correct answer would seem to be "nothing, please — try again in a few years at least," but the winning comedy Good Boys gets the STR ratio miraculously right. The thought of preteens swearing, porn-hunting and speculating wildly about what-goes-where, anatomically speaking, sounds more like horror than comedy, but Gene Stupnitsky and Lee Eisenberg, the writing team best known for its episodes of The Office, make it all seem like innocent fun. They place the guardrails early — a game of spin the bottle is as far as this will go, they assure us — and turn the quest for a kiss into a juice box jamboree of silly malapropisms, wild misbehavior and deep sexual confusion, sprinkled with real insight into a painful growing period.
