Dolphins
Did you know that dolphins has its own signature whistle to distinguish it from other dolphins, much like a human fingerprint? Dolphins have complex brains and signs of self-awareness.
In this, you will know few about the anatomy and senses of dolphins, and their behavior also.
So, dolphins have a streamlined fusiform body, adapted for fast swimming. The tail fin, called the fluke, is used for propulsion, while the pectoral fins together with the entire tail section provide directional control. The dorsal fin, in those species that have one, provides stability while swimming. Though it varies by species, basic coloration patterns are shades of grey, usually with a lighter underside, often with lines and patches of different hue and contrast.
The head contains the melon, a round organ used for echolocation. Dolphins and many species of toothed whales use their sense of hearing in a very sophisticated behavior known as this echolocation. Echolocation is a process where a dolphin emits a steady series of split-second "clicks" through its blowhole. The "clicks" are pulses of ultrasonic sound produced in a dolphin's nasal passages and focused in a large, lens-shaped organ in the forehead known as the melon. The melon concentrates the sound pulses into a directional beam. When the outgoing sound waves or “clicks" bounce off objects in their path, a portion of the signal is reflected back to the dolphin. The bony lower jaw of the dolphin receives the incoming sound waves and transmits them to the inner ear where they are converted into nerve impulses and then transmitted to the brain.
In many species, elongated jaws form a distinct beak; species such as the bottlenose have a curved mouth which looks like a fixed smile. Some species have up to 250 teeth. Dolphins breathe through a blowhole on top of their head. The dolphin brain is large and highly complex, and is different in structure from that of most land mammals.
Dolphins are social, living in pods
