ODD TV featuring strange and amazing facts of theese subaquatic creatures.

Dolphins;

We all have heared, dolphins are the only specie to make sex for pleasure, as humans. 

The complexity of language and communication is beyond our comprehension.

• Dolphins sleep by resting one side of the brain at a time. This  allows them to continue rising to the surface for air and to keep an eye  open to watch out for predators.
• Dolphins use echolocation to find food and navigate. This is a natural version of radar. 
• Dolphins can jump as high as 20 feet out of the water.
• The “killer whale”, or Orca, is actually a dolphin. 
• Dolphins are extraordinarily intelligent animals who also display  culture, something which was long-believed to be unique to humans  (although now recognised in various species). 
• Dolphins have been observed teaching young how to use tools. They cover their snouts with sponges to protect them while foraging. 
• Dolphins have several highly developed forms of communication. They  have a “signature whistle” which allows other individuals to recognise  them.
• Dolphins are altruistic animals. They are known to stay and help  injured individuals, even helping them to the surface to breath. Their  compassion also extends across the species-barrier. There are many  accounts of dolphins helping humans and even whales.

Whales:

They eat the smallest microorganism and algae,and have the most complex nervous system of the earth.

 

• The Blue Whale is the largest creature ever to have lived on earth. 
• Their tongues alone can weigh as much as an elephant. Their hearts, as much as a car.
• Amazingly, however, this giant of the ocean feeds on some of the  smallest marine life – tiny shrimplike animals called krill. A single  adult blue whale can consume 3,6000kg of krill a day.
• They mainly catch their food by diving, and descend to depths of approximately 500m.
• The whale’s mouth has a fascinating row of plates fringed with  bristles to help it filter its main source of food – plankton from the  water. There is what looks like a moustache of long bristles on the end  of each plate to help it hold the minute prey. With each mouthful, the  whale can hold up to 5,000kg of water and plankton. Having forced the  water out of its mouth, the whale licks these bristles with its fleshy  tongue.
• Although the blue whale is a deep-water hunter, as a mammal, it must  come to the surface of the sea to breathe. When it surfaces, it exhales  air out of a blowhole in a cloud of pressurized vapour that rises  vertically above the water for up to 9m. 
• Blue whales occasionally swim in small groups but usually alone or in pairs. They are thought to form close attachments.
• In spite of their bulk, these graceful swimmers cruise the ocean at over 8km/h, and can reach speeds of over 30km/h.
• Though we can’t hear them, blue whales are one of the loudest  animals on the planet, communicating with each other using a series of  low frequency pulses, groans, and moans. It is thought that in good  conditions blue whales can hear each over distances of up to 1,600km. 
• Scientists think they use these vocalizations not only to  communicate, but, along with their excellent hearing, to sonar-navigate  the dark deep oceans.
• Females breed only once every three years and gestation is between 11-12months. Females usually only have one young.
• A baby blue whale (calf) emerges weighing up to 2,7000kg and up to  8m long. New born whales are helped to the surface of the water by their  mothers and are often encouraged (nudged) by other females so that they  can take their first breath of air.  
• The calf is suckled in the water, drinking more than 600 litres of  milk each day and gaining about 90kg every day for its first year.
• Blue whales have few predators but are known to fall victim to  attacks by sharks and killer whales, and many are injured or die each  year from impacts with large ships. 
• It is thought that whales feel emotions.
