10 Weird Facts about Spiders: The Creepy Crawlers

Spiders are famous for their architectural skill that is displayed by weaving of web. Majority in the species prefer solitary life, alone in their cobwebs. They look eerie no doubts but they show such unique and weird characteristics that researchers across the globe are still trying to figure out the reasons behind these awestruck potentialities that these arachnids exhibit. Some of them are described below: 1) Bulky DNA The DNA of one spider egg is equal to the amount of genetic material of four humans combined. 2) Immortals There is…

Frogs Resort Competition via Cannibalism: The Voracious Predators

Cannibalism in the animal kingdom is very well known fact among the inhabitants. Animals whether big or small in their race for survival, resort to kill their competition by eating them. Animals like jungle king, lions are known to kill the offspring of the revival king to pave way for better future of its own offspring. But researchers say, the behavior of cannibalism can be also seen tiny wood frog tadpoles. These innocent looking tadpoles when hungry can eat other tadpoles present in the pool. Such behavior has also been…

Penis Discovered in Female Insect: Novel Structure in Evolution

While studying the Brazilian cave insects, researchers to their surprise discovered a penis like genitals in females and organ similar to a vagina in males. For the first time they have noticed, such an extreme switch of sex organs and have dubbed the newly revealed penis of the female insects as “gynosome” and “phallosome” for the vagina like organ in male insects.

Sightless Mechanism of Navigation: Mouth Suction by Cavefish

When it comes to visualizing environment, eyes play an important role. But there are other ways of navigation such as echolocation used by bats and dolphins. Recently, researchers studying Mexican blind cavefish (Astyanax fasciatus), have found a unique and new method of navigation. These fishes spend their entire life in the deep sea or dark caves, which are devoid of any source of light and so as the name suggests, their eyes are rendered useless and over the time the fish losses their eyeballs.

Tactile Stimulation and Reproduction go Hand in Hand Amongst Female Cockroaches

Generally, the antenna, key sensory organ of insects is known to aid insects in perceiving information about its surroundings such as availability of food, danger of predator, obstacles and potential mates and so on. They have many sensory receptors for audition, olfaction, balance, stability, gustation, graviception, thermo, hygro and mechanoreception, to name a few. They also play an important role during social interactions. In German cockroaches (Blattella germanica), during such social interaction, antennal contact alters juvenile hormone production which leads to an increase in female reproduction rate. In short the…

Sniffing Web Pheromones Helps Male St. Andrew’s Cross Spiders Determine Female Availability

Researchers from the University of Hamburg, Germany and Macquarie University in Australia, studying St. Andrew’s Cross spiders, have found that male spiders looking for suitable mates, smell the webs woven by females and determine the females are ready for mating. The researchers observed several specimens of the species and conducted numerous experiment in their laboratory and finally concluded that smelling the pheromones present on the female web, male spider make a decision whether to move closer to the female for mating or not.

Plants Uses Chemical Weapons and Employ Insect Armies to Defend Themselves

When we encounter a danger, the first thing that strikes in our mind is to run away and hide (though many of us might choose to give a fight). But the article is in the context of animals and plants. Animals when encounter any danger of being attacked, the first instinct is to escape from the danger is to run. Unfortunately, the plants cannot do that. Rather, plants in order to defend themselves from their predators have evolved various defense techniques such as chemical weapons and insect armies.

Dark Plumage helps in Flushing out Toxic Metals

Just like humans, animals living in urban areas are constantly prone to metal intoxication. In France, a team of researchers studying the level of metal intoxication in birds have found a strange relation between the color of the plumage and the level of metal toxin in the bird’s body. They observed that the birds with dark shade plumage were better at getting rid of metal toxin from their bloodstream.

Pandas Have A Functional Sweet Taste Receptor

The popular known fact that bamboo is the only food that panda exclusively feeds on, is not true. Researchers from the Monell Center have found that the panda has also liking for sweet food. The research, based on panda behavior and molecular genetics reveals the presence of taste receptors and confirms that the panda has a strong liking for natural sweeteners as fructose and sucrose.

Climate Change Slowing The Deep Ocean Currents

We recently covered an article explaining the vital role of the oceans in the global carbon cycle and the process in which oceans accumulate, transport and convert carbon molecules. But according to a recent research carried by Irina Marinov and Raffaele Bernardello from University of Pennsylvania and colleagues from McGill University, says that climate change is slowing down the deep ocean currents and can adversely influence the climate in the future.

Fidelity Can Be Seen In Owl Monkeys: Genetic Monogamy

Infidelity is very general trait to be observed in the animal kingdom. Maternal and paternal genetic tests have revealed that even the species that were considered to be faithful in their relationship, were often not loyal to each other. Merely about 10 percent of the species follow monogamy and are truly faithful to each other. However, according to a latest research led by University of Pennsylvania revealed that Azara’s owl monkeys (Aotus azarae) are remarkably devoted and faithful to their mating partners.

Sea Serpents Can Remain Dehydrated for Months: Combating Climatic Changes

Sea snakes as the name suggest, spend their entire life in the ocean. Researchers have always been curious to know how do these snakes survive in seawater and what method did they employ to satisfy the quench for fresh water. According to a latest research, the sea snakes though surrounded by water, unfortunately, remains thirsty and dehydrated for months.

Nothing Dies in Ocean: The Biological Pump

Carbon-based molecules are the prime element of biological compounds and play a crucial part in supporting different life forms on earth. The carbon molecules are continuously exchanged among the different reservoirs of carbon present on the Earth. Recently, researchers at the University of California Santa Barbara, used images received from the satellite, to analyze the importance of oceans in the carbon exchange also known as the global carbon cycle.
