Dolphin fish
Dolphin – Mammals, not fish, dolphins are not mainly fish, it is a mammal. They: Breathe in the lungs (lifted on the water) and give birth to a baby (the egg does not lay) The mother's milk has hair on the skin. So, scientifically dolphins = mammals, not fish. 2. Dolphin fish = mahi-mahi (mahi-mahi or dolphinfish) but in many areas, what is called "dolphin fish" is actually dolphinfish (scientific name: Coryphana hippurus). It is also called "Mahi-Mahi". It is a real fish – which breathes under water (with gil), lays eggs, and is caught as a fish. Looks very bright in color, slightly flattened. Although this fish is called "dolphinfish", it has nothing to do with dolphin.
Pink dolphin
There are many dolphins in the world, but the pink dolphin is quite popular. Amazon River Dolphin
Local name: Boto
Scientific name: Inia geoffrensis
This dolphin is found in the Amazon River and its tributaries in South America.
Especially in Brazil, Peru, Colombia, Venezuela, etc.
They are gray at birth.
They turn pink as they age — this may be due to blood vessels under the skin.
Some have a lighter color, while others have a darker pink.
The color may become darker during physical activity or excitement — much like a person's face turning red.They recognize turtles and tortoises from deep water. Quite popular with Americans.।।
Dolphin gender
There is a lot of information available about the sex and reproduction of dolphins. For example:
& Male Dolphin:
The penis of a male dolphin is located under the body, towards the belly, in a genital slit.
It is not visible in its normal state — it comes out when necessary (such as during reproduction).
The penis of a dolphin is very flexible and controllable, and is much more mobile (prehensile) than that of other animals, meaning that it can touch or feel something with it.
& Female Dolphin:
The vagina of a female dolphin is located under the belly, in the genital slit.
On both sides of it are mammary slits (breast holes), from which it drinks milk.
It is generally difficult to determine the sex of a dolphin from the outside, because:
The penis or vagina does not hang outside.
However, it can be identified by the number of slits in the lower abdomen.।।
River dolphin
We know that river dolphins refer to dolphins that do not live in the sea, but in rivers and freshwater environments. There are some dolphins in the world that are specially adapted to living in rivers. These dolphins are called "River Dolphins" in English.
River dolphins generally live in freshwater (rivers, lakes, canals).
Lungs (breathe above water) belong to the mammalian class and accept fish, shrimp, small crabs, etc. as food.
