The secret weapon of some animals: ultrasound

Did you know that some animals use ultrasound to protect themselves? Ultrasound is sound waves with a frequency that exceeds the range of human hearing. Although humans cannot hear these sounds, many animals do, and they use them for a variety of purposes, including communication, navigation, and predation ultrasonic-sounds.

A bat uses ultrasound to navigate and hunt.

One way animals use ultrasound for defense is to frighten or scare off predators. For example, during flight, bats emit high-frequency ultrasonic pulses that help them navigate in the dark and avoid obstacles. These ultrasonic pulses can also be used to scare or even harm predators such as moths.

Some animals also use ultrasound to notify each other of danger. For example, meerkats emit a high-pitched alarm call when they see a predator, which alerts other meerkats in the area to the danger.

Ultrasound can also be used by animals to attack predators. For example, some dolphins use ultrasound to create a beam of sound that can stun or even kill fish.

Animals' use of ultrasound is a fascinating example of how animals have adapted to their environment. Using ultrasound, animals can communicate, navigate, and protect themselves in ways that would otherwise be impossible.

Here are some of the animals that use ultrasound for defense:

Bats: Bats use ultrasound to navigate in the dark and avoid obstacles. They also use ultrasound to scare or scare away predators.

Meerkats: Meerkats use ultrasound to communicate danger to each other.

Dolphins: Dolphins use ultrasound to create a beam of sound that can stun or even kill fish.

Shrews: Shrews use ultrasound to stun prey.

Mice: Mice use ultrasound to signal danger to each other.

What scientists say:

Scientists are still learning about the many ways that animals use ultrasound. However, it is clear that ultrasound is an important tool for many animals and plays a vital role in their survival.

As we learn more about animals' use of ultrasound, we can develop new technologies that can help us protect animals and their habitats. For example, we could develop ultrasonic devices that can be used to repel pests or to warn animals of danger.

The use of ultrasound by animals is a fascinating area of research that can teach us a lot about the natural world. By studying how animals use ultrasound, we can better understand their behavior and ecology. This knowledge can then be used to help us conserve animals and their habitats.

Green Energy Costs to 2035: Prices & Trends

Green Energy Costs to 2035: Why Solar and Wind May Rise While Batteries Fall The global renewable energy revolution is accelerating. Governments, corporations, and households are investing billions in green energy systems. Yet a paradox is emerging: while the cost of generating solar power and wind energy may increase in the coming decade, battery storage prices are projected to decline significantly. Why is this happening? And what will it mean for consumers and investors by 2035? This evergreen analysis explores the economic forces shaping energy markets, provides price forecasts in U.S. dollars, and explains how global trends could redefine the cost of clean electricity. Why Green Energy Became So Affordable Over the past 15 years, renewable technologies have experienced dramatic cost reductions. According to the International Renewable Energy Agency (IRENA) , global weighted-average costs of solar photovoltaic electricity dropped by nearly 90% between 2010 an...

NASA’s Webb Uncovers Methane on Interstellar Comet 3I/ATLAS: A Cosmic Breakthrough

Imagine looking up at the night sky and realizing that the tiny, distant glimmer you see isn't just a remnant of our own cosmic neighborhood, but a visitor from a completely different solar system. The universe is whispering secrets to us, and for the first time in human history, we have the ears to listen. The James Webb Space Telescope (JWST) has just shattered our understanding of interstellar travelers by detecting methane on the comet 3I/ATLAS. This isn't just a chemical reading; it is a profound connection to the unknown, a bridge built of stardust and science that links our home to the mysterious voids between stars. The Arrival of an Interstellar Messenger For decades, astronomers dreamed of catching a glimpse of an object originating from outside our solar system. In 2017, we met 'Oumuamua, and later, 2I/Borisov. However, the discovery of 3I/ATLAS —often referred to as an interstellar comet—has provided us with a laboratory like no other. When this icy wanderer...

Top 10 Most Endangered Animals in the World (2025 Update)

Updated in 2025: Habitat destruction, climate change, and poaching are pushing countless species toward extinction. Here are the 10 most endangered animals in the world right now – and how we can still help save them. Sources: IUCN Red List, WWF, National Geographic, Wildlife Conservation Society 🦍 1. Cross River Gorilla ( Gorilla gorilla diehli ) Status: Critically Endangered Population: Fewer than 300 This elusive gorilla species lives in remote forests on the Nigeria-Cameroon border, threatened by habitat fragmentation and illegal hunting. 🐯 2. Amur Leopard ( Panthera pardus orientalis ) Status: Critically Endangered Population: About 120 Native to the Russian Far East, it’s the rarest big cat, threatened by poaching and habitat loss. 🐢 3. Yangtze Giant Softshell Turtle ( Rafetus swinhoei ) Status: Critically Endangered Known survivors: 2 Only two are known to exist. Breeding efforts are critical to preventing extinction. 🐬 4. Vaquita ( Ph...
