Animals

Fish are also capable of feeling pain, especially when they live in captivity. So how do you ensure that they live a calm and peaceful life in the aquarium?

First of all, it is necessary to feed the pets with suitable food. The amount of food should be appropriate for the size and age of the fish. They will compete for food, especially if there are a lot of them, so the young ones risk going hungry.

Fish produce a lot of waste, and ammonia, nitrites, nitrates accumulate in the aquarium water. There are special monitoring devices that report water quality.

Fish sleep patterns resemble human sleep patterns. They need darkness to rest, so lights should not be on 24 hours a day.

Scientists from the Schmidt Ocean Institute have discovered an unexplored hydrothermal vent off the Galapagos Islands, which has sparked long scientific discussions over the past 20 years. The important discovery was helped by lobsters, whose footprints led directly to the unique formation on the seabed.

The site is larger than a soccer field and consists of five geyser-shaped chimneys and three hot water springs.

They are essentially fissures in the rock spewing boiling water. Experts have known of their existence in the area for decades, but the search has been hampered by the transparency of the ejected water and the lack of large clouds of steam. Chemists, geologists and biologists had long tried to find the hydrothermal field, but it was the galateid crabs, also known as squat lobsters, that made the difference.

An American biotechnology firm from San Francisco has introduced a drug that slows down the aging of large breed dogs. According to the developers, the drug is effective when used for animals weighing 18 kilograms or more. It also prevents age-related diseases in pets.

Veterinarians say that the normal lifespan of a dog rarely exceeds 13 years. However, large dogs pass away earlier and age faster. This is due to elevated levels of IGF-1, a growth hormone. The drug is designed to reduce its content. The drug is administered by injection at intervals of 3-6 months. Research is also being conducted to develop daily tablets.

Specialists have long been searching for a method of establishing close contact with representatives of fauna. Elephants, octopuses, ravens and whales are considered the most suitable candidates. The specialists were able to establish communication with the latter.

Scientists have uncovered a method for communicating with whales. To find the optimal signal, they recorded the sounds of a pack of humpback whales and ran them through the water to test the animals’ response.

A whale named Twain (38 years old) soon responded. As she swam up to the vessel, she began to “talk.” Researchers played the sound at different intervals, and the female responded in the same rhythm. Scientists believe that Twain conducted a kind of dialog with a sound message.

A recently deceased dog named Bobi has been removed from the Guinness Book of World Records, where he previously held the place of honor as the oldest dog on the planet. According to experts, his stated age may not have been true.

Bobi, who was a Portuguese guard dog, passed away last fall. According to his owners, he was 31 years and 165 days old at the time, which in human terms would equate to about two centuries.

But upon investigation, experts found no reliable evidence of this. Bobi was registered in the Portuguese government database only in 2022, and a year later he had already passed away. In addition, experts have noticed that in the photo of young Bobi he had paws of white color, and closer to old age they have acquired a brown tint. Perhaps the photos from the end of the 20th century belonged to another animal.
