Sounds have waves. The frequency of sound is how close together the sound waves are. The closer together the waves, the higher the frequency or pitch. You can think of this like the beach during a storm, when waves hit the beach more often.
Dogs and people hear about the same at low frequencies of sound (around 20Hz). This changes at high frequencies of sound, where dogs hear up to 70-100kHz, much better than people at only 20kHz. Dogs hear sound frequencies at least three times as high compared to people.
You may have wondered how those special silent dog whistles work? They make high-frequency sounds that dogs can hear but we can’t. Because dogs can hear higher frequencies than us, there are a lot more sounds for dogs to hear.
They can also hear sounds that are softer or farther away, as far as a kilometre. That means dogs can be more sensitive to loud sounds. This is why some dogs are scared of fireworks or thunderstorms. It is also why a dog might bark at a sound you cannot hear.
When sperm whales need a nap, they take a deep breath, dive down about 45 feet and arrange themselves into perfectly-level, vertical patterns. They sleep sound and still for up to two hours at a time between breaths, in pods of 5 or 6 whales, presumably for protection. No one knew whales slept vertically until a 2008 study documented the behaviour. And no one captured really good photography of it in the wild until 2017. French photographer Stephane Granzotto was documenting sperm whales in the Mediterranean for his book on the creatures when he came across these sleeping whales.
Hey guys! In this post, I will try to answer or rather speak my mind out on a question that popped into my mind. A question of ethics.
“Aren’t humans animals, too? Well… Then all animals kill other animals for food! So why isn’t it justified if humans do it?”
Okay… I have been pondering quite a lot about it, and I think I can contradict it.
The very fact, that we have a conceiving, thinking, and processing capability greater than any other animal, makes us REALLY different.
A lion might kill its prey, but can it grow crops like humans? Can whales cultivate the ocean floor? No! But we can do it all, we humans can!
Nature offers us a choice, a gift of knowledge. We can either exploit other animals or save them. Humans have never been gentle. Greed always takes control. We can’t sustainably survive ever by eating animals and destroying ecosystems.
After 300,000 thousand years of our living on planet Earth, we still miss the point that all lives matter the same! When one can have such strong bonds and sentiments with one’s family members, why doesn’t one understand, that all species are children of mother Earth itself?
And doesn’t the word ‘ethic’ mean differently to different entities? A lion’s ethic is to survive, keep up its pride! The very essence of the meaning of ethics kicks up a notch when we humans are in the frame.
Be sure to not get this idea in your head, that if we humans don’t eat meat, then there will be chickens, and goats overrunning the roads! They are bred and not caught from the wild! Nothing like that will ever happen.
We can consider acting like wild animals when the situation is really EXTREME. When we have no possibility other than starve. Killing animals otherwise, with our advanced brains, will be really foolish and hypocritical.
The snake is one of the most established spiritual symbols known, worshipped in some religions and detested in others. In Christianity the snake was held responsible for luring Eve to eat the forbidden fruit – which changed the entire course of mankind. While in Eastern cultures, the snake is considered to be a symbol of regeneration, death and rebirth.
Telepathy is a type of psychic power that allows mind-to-mind communication. There are varying degrees of telepathy, but in powerful cases, the psychic can communicate clear and complete thoughts in just a blink of an eye. In addition, telepathy isn’t only limited to human to human interactions. Animal telepathy is also a popular sect of psychic practice.
Bioaccumulation is the gradual accumulation of substances, such as pesticides or other chemicals, in an organism. Bioaccumulation occurs when an organism absorbs a substance at a rate faster than that at which the substance is lost or eliminated by catabolism and excretion.
Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.
Approximately 46% of the 79 thousand tons of ocean plastic in the Great Pacific Garbage Patch is made up of fishing nets, some as large as football fields, according to the study published in March 2018 in Scientific Reports, which shocked the researchers themselves who expected the percentage to be closer to 20%.
Fishing nets lost, abandoned or discarded at sea – also known as “ghost nets” – can continue killing indiscriminately for decades and decades, entangling or suffocating countless fish, sharks, whales, dolphins, sea turtles, seals and marine birds every year. An estimated 30% percent of the decline in some fish populations is a result of discarded fishing equipment, while more than 70% of marine animal entanglements involve abandoned plastic fishing nets.
Zoologists and wildlife biologists study animals and other wildlife and how they interact with their ecosystems. They study the physical characteristics of animals, animal behaviors, and the impacts humans have on wildlife and natural habitats.
