DOLPHIN CLASSIFICATION
DOLPHIN
Dolphins are highly intelligent marine mammals, besides the natural systems that complement their bodies are very complex. So many technologies are inspired by dolphins. One example is the skin of a dolphin which is able to reduce friction with water, so that dolphins can swim with little water resistance. This is what swimmers use to design swimsuits that resemble dolphin skin.
Dolphins have a system that is used to communicate and receive stimuli called the sonar system, this system can avoid objects that are in front of the dolphins, so they avoid collisions. This technology is then applied in submarine radar manufacturing. Dolphins are mammals because dolphins are mammals. They live in the sea and rivers throughout the world. Dolphins are relatives of whales and dolphins. There are more than 40 types of dolphins
Newborn baby dolphins will be brought to the surface by their mothers so they can breathe air. Dolphins need to rise to the surface to breathe to stay alive. Dolphins breathe through air holes located above their heads. Its sleek and slim body is perfect for swimming. Mother dolphins feed their children with savory milk and provide energy for their children to grow up quickly. Every child dolphins are always near his mother, so his mother can protect from danger. Dolphins always maintain relationships with their children to grow bigger. Mother dolphins call their children with special whistles that they can recognize.
Dolphins live and work in groups or are called herds. They often play together. A dolphin can not sleep well under water. He can sink. Therefore, he was half asleep several times a day. Dolphins eat squid and fish like gray mullet fish. Sometimes dolphins herd fish herds for easy capture. Dolphins find their way by sending sounds in the water. If the sound hits an object, the sound will be reflected back as an echo. Sometimes, noise in the sea due to oil drilling can confuse dolphins. They will experience difficulties in sending and receiving messages. Because dolphins can communicate, dolphins are said to be the most intelligent animals, more than chimpanzees.

The Chordata phylum is a group of animals, including vertebrates and some animals that resemble invertebrates that have similar characteristics.
# Chordates include animals that have the following characteristics:
- Has a notocord, which is a hard but flexible bar-shaped skeleton. The notocord is located between the digestive tract and the nerve cord, extending along the body to form a skeletal axis.
- Having a single nerve cord, perforated located dorsal to the notocord
- has an enlarged anterior end of the brain.
- Has a tail that extends posteriorly toward the anus.
-Have pharyngeal gaps
# Mammals or mammals are a class of vertebrate animals which are mainly characterized by the presence of mammary glands.
# Ordo Cetacea (L. cetus, whales) including whales, dolphins and dolphins. Cetus is Latin and is used in biological naming which means "whale"; the original understanding, "large sea animal", is more common.
# Odontocetim is infraordo of the subordo artiodactyla cetacea, including sperm whales, beaked whales, dolphins, etc.
# Dolphins belong to the Delphinidae family. This word comes from the Greek δελφύς (delphus) which means womb, because ancient people often called them 'fish' with the womb
Baby
Baby dolphins (also called calves) are born after 11-12 months of pregnancy.
dolphin fetus

Teenager
After 3-6 years old, juvenile dolphins will decide on their own way of life to remain in the herd's flock or leave the mother and herd.
Adult
At the age of 5-13 years, adult female dolphins will return to the group where they were born. A herd of dolphins is also known as a pod, for a herd with hundreds of dolphins in it is often referred to as a superpod. Dolphins reach sexual maturity at around 7-12 years for females and 10-15 years for males.

male dolphin reproductive organs
Adult male dolphins like to get along and move between females. They are free from responsibility and just wandering, the only role they play is marriage. Whereas adult females play a major role in all decisions, especially in protecting and feeding their children.
Mating period
Around the age of 12 years, male dolphins will find a partner to breed. They are sometimes involved in acts of aggression as a form of competition for females. Mating season usually occurs during spring. Dolphins will explore the period of introduction with a partner for days. At this time, the couple will always be seen swimming together and caressing each other with their fins. The mating process is very fast, usually in seconds.
Birth Process
Unlike terrestrial mammals, the birth process of dolphins starts with the tail coming out first. This is because if the head comes out first, there won't be enough time for the baby to reach the surface to breathe. The birth process of a dolphin takes about 3 hours, and during this process there will be blood, which will lure predators like sharks to approach. To protect the mother dolphin during childbirth, other dolphins in the group will form a circle around it. Newborn baby dolphins will be assisted by the mother brought to the surface in order to breathe air. Female dolphins will usually give birth about every 4 or 5 years. They choose to care for their children first until they are quite independent, before they are pregnant with their next child. A dolphin can have up to 11 children in their lifetime, and can still mate until the age above 40 years. The life expectancy of male dolphins is 40 years, and 50 years for females.
