Animal Week : Dolphins

"Dolphins !"

26 July Monday - Dolphins are awesome !

Dolphins are marine mammals , not fish.Most people thought they are fishes , they do look like fishes but they are actually mammals.Sharks are fishes but Dolphins are not fishes since Dolphins breath by using their lungs and Sharks breath by using their gills.There are almost forty species of dolphins in the seventeen genera.They are found anywhere !!! Mostly shallow seas , they are carnivores.

Dolphins are the most intelligent animals in the world , their friendly appearance and playful nature attracts humans.Their traits made them popular among human culture.Dolphins are often regarded as one of Earth's most intelligent animals, though it is hard to say just how intelligent.Compared to many other animals in the world , dolphins have been studied extensively on their social behavior both in the wild and in the captivity.

Dolphins live by pods.Pods are like groups of dolphins forming and living together.Sometimes , pods can be merged with other pods to form super pods.Super pods often have about 1000 dolphins in them.This proves dolphins are very social animals.Individuals communicate using a variety of clicks, whistles and other vocalizations. They make ultrasonic sounds for echolocation.They are like radio waves , transmitting to each other in order to communicate and to express themselves towards each other.We humans use our mouths , they use ultrasonic sounds.

Dolphins often talk to each other inside pods.Remember , they are highly social animals so them interchanging is not really a surprise thought.Dolphins can establish strong bonds for each other.They would stay and protect with the ill and injured.They would even help sick dolphins to breathe by bringing them up to the ocean surface.Dolphins tend to play with each other too.

Dolphins are known to have sex for reasons other than reproduction, sometimes also engaging in homosexual behavior.Even animals can be gay and lesbians , not that I got a problem with homosexuals.I respect them just like any other out there , they are just people with a different way of life and we must respect their choice.Sexual encounters in dolphins can be violent , the male dolphins sometimes would be aggressive towards both males and females.Also , they would also show sexual behaviors towards human lol.

Generally, dolphins sleep with only one brain hemisphere in slow-wave sleep at a time, thus maintaining enough consciousness to breathe and to watch for possible predators and other threats.They are like CCTVS , but sleeping and could beat you up lol.In captivity , dolphins sleep with both of their eyes close.Maybe they thought it was safe being inside a cage.

Dolphins have a lot of threats.Bigger predators like sharks and killer whales tend to feed on dolphins.Dolphins are also vulnerable to parasitic attacks and diseases.Humans are also hunting dolphins and sometimes killed them by mistake when using various fishing methods.Its our job to save these animals , they are beautiful animals and should be protected.Fortunately , there are organizations all around the world dedicated to protect dolphins from the verge of extinction.

Ops my pencil is broken , DOLPHINS
