The World Biggest Snakes


The Wildlife Conservation Society has, since the early 20th century, offered a large cash reward (currently worth US$50,000) for live delivery of any snake of 30 feet (9.1 m) or more in length. This prize has never been claimed. In any case, measuring a snake that is stronger than a person is not an easy task. It was found that two scientists independently measuring the same 12-foot (3.7 m) plus snake showed a variation of more than 20% in their results.

Common names


Local names in South America include the Spanish term “matatoro,” meaning “bull killer,” and the Native American terms sucuri and “yakumama.”

A possible origin for the common name anaconda is the Tamil anaikondran, meaning “elephant killer”, or anaikkonda, meaning “having killed an elephant”. A name first used in English to name a Ceylonese python, it erroneously was applied to a large South American boa, called in Brazil “sucuri”. The word is of uncertain origin, and no snake name like it now is found in Sinhalese or Tamil. Another suggestion is that it represents Tamil. It is unclear how this name originated so far from the snake’s native habitat; possibly this is due to its vague similarity to the large Asian pythons.


There are some debates about the maximum size of these snakes. Mehrtens (1987) states that the average adult length for the green anaconda, E. murinus, is 18 to 20 feet (5.5–6.1 m), with 25 feet (7.6 m) specimens being very rare. He sets a more conservative maximum at 23 feet (7.0 m). Estimates of 35 to 40 feet (11–12 m) (see Giant anaconda) are based on vague data and should be regarded with caution. In a study of 1,000 specimens captured in Venezuela, the largest was 17 feet (5.2 m) long and weighed 100 pounds (45 kg).


I think these are anaconda, and this’s some information about anaconda
Eunectes is a genus of non-venomous boas found in tropical South America, commonly called anacondas. An aquatic group of snakes inhabiting swamps and rivers, its members include some of the largest snakes in the world. Despite this, little was known about them until recently. The name Eunectes is derived from the Greek word Eυνήκτης, which means “good swimmer.” Three species are currently recognized.

Babies have a sense of rhythm from early on in life


It will be months before they talk, walk or even sit up. But at just a day old, babies have a strong sense of rhythm, say researchers.

Newborns are also sensitive to pitch and melody, they found.

Experts said that introducing a child to music at an early age could enhance these innate musical abilities and also help them learn to talk.

The fledgling musical talent was discovered by Hungarian researchers during a study of more than 100 boys and girls who were only one or two days old.

They played the babies music as they slept and measured their brain activity.

The researchers found that their brains computed changes in beat, tone and melody.

For instance, if a key beat was missed from a rhythmic pattern, the baby's brain registered the change.

A change in pitch, similar to that between male and female voices, also provoked a reaction.

The Hungarian Academy of Sciences study was part of a threeyear European project on how the brain processes music and other sounds, co-ordinated by Dr Susan Denham, of Plymouth University.

She said: 'What is perhaps most significant is that not only do babies' brains register changes in beat, pitch and simple melodic patterns but they do so more or less automatically, as they are fast asleep during these experiments.

'People come into the world with brains that are wired-up to detect patterns'.

Dr Denham added: 'A lot of music reflects the rhythms and contents of speech. If you are listening to music you will also probably be more sensitive to speech rhythm.'

Fantastic Surfing

Surfing is a surface water sport in which the participant is carried along the face of a breaking wave, most commonly using a surfboard, although wave-riders may make use of kneeboards, body boards (aka boogie boards), kayaks, surf skis, and their own bodies. Surfing-related sports such as paddleboarding and sea kayaking do not require waves, and other derivative sports such as kitesurfing and windsurfing rely primarily on wind for power, yet all of these tools may as well be used to ride waves.

Two major subdivisions within contemporary stand-up surfing are reflected by the differences in surfboard design and riding style of longboarding and shortboarding.

In tow-in surfing (most often, but not exclusively, associated with big wave surfing), a surfer is towed into the wave by a motorized water vehicle, such as a jetski, generally because standard paddling is often ineffective when trying to match a large wave's higher speed.
