In the Russian language, as in all other dialects, there are words similar to each other in sound and spelling. People often ask each other: in June or July? After all, an error in time can be worth a lot. There are words that are pronounced exactly the same.
Killer whale or killer whale?
For example: how is the word "killer whale" spelled? This question is probably asked by students studying biology. How to: killer whale or killer whale? The spelling depends on the meaning of the word.
Who is the killer whale?
Killer whale is a marine mammal from the order of cetaceans. The killer whale belongs to the dolphin family. Why does she have such a name? Presumably due to the high, slightly curved dorsal fin of the males, which resembles a scythe for mowing grass.
What is a killer whale?

Thin feathers stretch along the sides of the tail and lengthen it. These feathers can resemble braids of Russian girls. The name of the killer whale came from the word "braid".
20th century spelling
Another difficulty may arise in the spelling of the name of a marine mammal. Killer whale or killer whale? How to spell a dolphin name? Such questions arise when reading old sources. In the first half of the 20th century, both spellings were considered correct. However, at present, only one is used, namely, “orca”. Zoologists saved us from confusion with concepts.
Killer Whale Fish
That's not all. In the taxonomy of fish, there is a whole family of killer whales from the order Catfish. For example, in eastern Eurasia, a killer whale is found in rivers. She is not the subject of fishing. However, it is caught with interest by amateur fishers. Once on land, the fish begins to creak quite loudly. How to: killer whale or killer whale?

Description of a killer whale
Large dolphin with a black back, white belly. White spots on the sides of killer whales: one in the head, and the second closer to the tail, moving away from the white part of the ventral side. The shape of the spots makes it possible to distinguish individual individuals, even the human eye.
In colder regions of the oceans, white often becomes yellow-green or brownish due to diatoms growing on killer whales.
The killer whale eats fish, pinnipeds. Moreover, the specialization of individual groups of killer whales on this or that food is noticed. If one group prefers hunting for schools of fish, then the other, living close to the first, can specialize in seals.
The killer whale is a ferocious predator that distinguishes it from other dolphins that feed on fish. The killer whale stands on top of the food chain. In the absence of fish and seals, it attacks whales and other dolphins. Choosing a victim, the group will not let her go alive. Chunks of meat come off huge production. A seal lying on an ice will surely slide into the mouth directly into the mouth of a member of the group. After the sea lion, the killer whale can jump ashore and, grabbing it with huge teeth, which are about 13 centimeters long, can return to its native element.
However, the killer whale does not touch a person. Apparently, this representative of the dolphin family has an incomprehensible to man love for us, people. It can attack a person if he feels danger or is under stress during prolonged detention in captivity.
Killer whales are unusually generous and kind to each other. They seem to have a human understanding that there are weak members in the group. Ferocious predators take care of the sick and old, protect mothers with children. Conflicts never grow into a fight, as happens in human society. The angry killer whale only slaps its tail in the water.
Description of killer whale
Barn swallow settles side by side with a man. It has nests on the buildings of people: under the eaves or even inside buildings in the presence of an opening for the passage of birds.
The killer whale body is elongated, the wings are sickle-shaped, which makes it possible to deftly perform maneuvers in the air. A tail with a large notch and very long lateral tail feathers - this sharply distinguishes it from other swallows. The beak is short and wide, which is convenient for grasping insects on the fly.
The dorsal side of the body is black and the belly is white. The throat is red.
He likes to sit on wires. It constantly chirps.
It builds a nest of clay and silt, which it blinds with its own saliva. For strength, it adds straws and hair to the material. He returns to his favorite building of man annually. However, every spring he builds a new nest next to the old one. Lines it with feathers and hairs.
It feeds on insects, which it usually catches on the fly. In inclement weather, with a weak activity of insects, it collects them on the fly from surfaces: from the walls of buildings, from grass.
The swallow dwells around the globe, except for Australia (where vagrants can meet) and Antarctica. In the north flies to Greenland, Iceland (sometimes nests here), New Earth. The Barn Swallow is a migratory bird. Nesting in the middle lane individuals fly for wintering to Africa, India, southern China.
The killer whale is perfectly adapted for flight. Biologists distinguish it from other swallows by swift flight with frequent smooth or unexpected maneuvers. So the killer whale hunts, skillfully grabbing midges and mosquitoes on the fly, saving us from the mean.
Why does the killer whale choose a neighborhood with a person and build its nests right on people's houses? The fact is that the barn swallow is a bird of rocky areas. In nature, it nests in shallow caves or holes in rocky shores and low mountains. Human buildings are surprisingly reminiscent of rocks with beautiful recesses for nests. Due to the huge number of buildings in the world, many birds spread widely around the world, whose biotope previously served only as a mountainous area. These are well-known jackdaws and blue pigeons. The killer whale chooses small settlements of people to avoid a factor of concern.
By the flight height of the swallows, you can really determine the weather. At low pressure, insects fly closer to the surface of the earth, followed by swallows. As atmospheric pressure rises, insects rise high into the sky. Swallows rise after food.
Description of catfish killer whales
Small and medium sized catfish. The body is trihedral. Dorsal and pectoral fins with spikes are distinguished from other catfish. The antennae are 2-3 pairs. The eyes are covered with a film. There is a fat fin. There are no scales. The whole body is covered with poisonous mucus, so an injection with thorns is painful.
Orcas live in fresh waters of Asia and Africa. In Russia, in the Far East, 4 species from 2 genera live.

Aquarists like to keep catfishes in aquariums. Some species of fish are brightly colored and arouse interest in behavior.
Nanais call these fishes "kakakta". It is believed that the Russian name "killer whale" comes from Nanai.
Killer whale is one of the members of the family. It creaks with jagged rays of fins. Active for the most part at night.
We figured out the spelling of various representatives of the fauna. The question of whether the killer whale or killer whale is correct is important for identifying the animal. The same pronunciation was found in different species of vertebrates: a representative of mammals, birds and fish. This happened during the formation of the names of living objects.
