Whales: Giants of the Ocean

Whales are among the largest and most remarkable animals on Earth. These marine mammals live in oceans around the world, from warm tropical waters to the cold seas surrounding the poles.

Life Beneath the Surface

Although whales spend their lives in water, they breathe air through blowholes located on top of their heads. They must regularly return to the surface to breathe before diving again in search of food or traveling through the ocean.

Whales are warm-blooded, give birth to live young, and nurse their calves with milk. A thick layer of fat called blubber helps protect them from cold water and stores energy during long migrations.

Two Main Groups

Whales are generally divided into baleen whales and toothed whales. Baleen whales filter small animals from the water using flexible plates inside their mouths. This group includes blue whales, humpback whales, and gray whales.

Toothed whales use teeth to catch fish, squid, and other prey. Many of them also use echolocation, producing sounds and listening for returning echoes to understand their surroundings. Sperm whales, belugas, and orcas belong to this group.

The Blue Whale

The blue whale is the largest known animal to have ever lived. An adult can grow longer than a city bus and weigh well over one hundred tonnes. Despite its enormous size, it feeds mainly on tiny crustaceans called krill.

Communication and Migration

Whales communicate using clicks, whistles, pulses, and complex songs. Some sounds can travel across great distances underwater. Humpback whales are especially famous for their long, patterned songs.

Many species migrate thousands of kilometres each year. They often feed in cold, nutrient-rich waters before traveling to warmer regions where they mate and give birth.

Protecting Whales

Commercial hunting once caused severe declines in many whale populations. Today, whales also face threats from fishing gear, ship collisions, underwater noise, pollution, and changes to ocean ecosystems.

Conservation programs, safer fishing practices, protected habitats, and international cooperation can help whale populations recover. Protecting whales also supports healthier oceans because these animals play an important role in marine food webs and nutrient cycles.

Take it with you when you go to the police to sort things out, utilities that lends money when drink and then that does not remember, to the chief on kovёr,
etc. This little thing will come in handy as the irrefutable proof for all possible disputes.

The coffee cans-large surveillance camera Withings can be used as a burglar protection, baby monitor and night vision goggles. On top of a room air sensor is still fitted.

Withings Home: If “multifunctional” really even true. Enlarge The French manufacturer Withings has unveiled at the IFA a product called “Home” – a multifunction device that is actually worthy of the name: The coffee cans large part camera, speaker, light and ambient air sensor in one. The video recordings of the HD camera can pick up on tablet or smartphone at any time. The lens is very wide angle: 135 degrees. Particularly proud of the Withings engineers are on the low latency: The video comes with less than a second delay at the caller. For this, however, the camera requires a network cable, wireless does not exist.

During the video streaming on mobile device, you can also speak into the audio signal is output from the built-in speaker of the Withings device. It also works in the opposite direction – so you can also use as a room monitor Home. Per app can be set that you get a notification when the Withings device registers a loud sound or movement. There is also a night vision function. And: Per App, you can activate a colored LED lamp – there goes Schlummerlicht.

The associated home app displays notifications and actual sensor measurements in a diary.

Enlarge The Withings device has also happen to be built a whole range of sensors: So you can view the ambient temperature and the humidity in the mobile app (iOS and Android also expected). Another sensor measures the VOC level – ie volatile organic compounds (Volatile Organic Compound). These compounds can be made, for example, of building materials, furniture and carpets – and permanently make you sick (“Sick Building Syndrome”).

All data is apparently stored on Withings servers, because you can old recordings and notifications in retrospect view in a timeline view. Whether the cloud storage can be disabled, is still unclear.

Withings Home to come in the fall for 200 euros on the market. Also on display at the IFA: Withings’ Activity Tracker analog Activité. They should be available in the fall for 390 Euros.
