Cats and people have been living together for thousands of years. Nowadays, domestic cats are extremely popular pets. According to statistics, they are even more popular than dogs. There is no doubt that cats love people as much as people appreciate them. Maybe it’s because cats and humans share some physiological traits. For instance, a cat’s brain is more similar to a human brain than a dog’s. The regions of the brain responsible for emotion are identical in both humans and cats. Cats also have A and B blood types, just like people.

Nowadays people prefer communicating online. However, 50 years ago people sent paper letters to each other. It was the norm to have a mail box full of envelopes with letters. The envelopes were used for keeping letters and documents. The first envelopes appeared in England in the first half of the 19th century. In Moscow, massive sales of envelopes started in 1846. The first envelopes were made of white paper. They were of a different format. To post a letter people needed round hand-made stamps. The stamps were fixed in the top right corner of the envelope. In St. Petersburg, stamps were blue, in Moscow they were red. Two years later, envelopes spread over the whole territory of Russia.

This fish is called the Black sea devil. We don’t know much about it. It lives deep in the darkness of the sea and seldom comes up. Scientists aren’t even sure how long it lives. The amazing fact is that the Black sea devil can perfectly adapt to its environment. They have sharp teeth, a big mouth arid beautiful fins used for swimming and hunting. Male fish live on the back of female ones that are much bigger in size. Not long ago, a Black sea devil was filmed in its natural environment for the first time. The fish was then brought to the surface alive for further monitoring. It was placed in a cool, dark container. Scientists want to know if it can sense magnetic fields like sharks do. A set of experiments will help to find out.
