Bats Hunting Prey Technique

Bats are nocturnal creatures. On daylight hours the sleeping and they are hunting and feeding during the night.

       The basic tool for hunting is the echolocation, because they are blind. Echolocation is the use of sound wave and echoes to determine where objects are in space.

Bats have adapted very large ears to gather and process as much sound data as possible. It is very similar to the sonar utilized by dolphins and wales. Insects flying at night are nearly invisible to vision-orientated predators and can be seen only   by using echolocation.

While echolocation paints a very clear picture of a bat’s surroundings, there are some disadvantages to echolocation. Bats have to continually vocalize to be able to create and  hear echoes off their surroundings, and bats cannot listen for an echo while vocalizing.

        When the sound waves produced by these sounds hit an insect or other animal, the echoes bounce back to the bat, and guide them to the source.

            It is amazing that they can catch anything at all.

BEE WAGGLE DANCE

By performing this dance, successful foragers can share information about the direction and distance to patches of flowers yielding nectar and pollen, to water sources, or to new nest-site locations.

The direction and duration of waggle runs are closely correlated with the direction and distance of the resource being advertised by the dancing bee. For cavity-nesting honey bees, flowers that are located directly in line with the sun are represented by waggle runs in an upward direction on the vertical combs, and any angle to the right or left of the sun is coded by a corresponding angle to the right or left of the upward direction.

A waggle run oriented 45° to the right of ‘up’ on the vertical comb (A) indicates a food source 45° to the right of the direction of the sun outside the hive (B). The abdomen of the dancer appears blurred because of the rapid motion from side to side.

The direction the bee moves in relation to the hive indicates direction; if it moves vertically the direction to the source is directly towards the Sun, the duration of the waggle part of the dance signifies the distance.

But the best part is that the bees are changing their dance according to the sun direction. Therefore, bees that follow the waggle run of the dance are still correctly led to the food source even though its angle relative to the sun has changed.

Honeybees accumulate an electric charge during flying and when their body parts are moved or rubbed together. Bees emit constant and modulated electric fields during the waggle dance.

Archer Fish Shooting Prey

What do you know about how Archcer Fish are hunting their prey? 

Archer Fish are shooting down the prey from outside the water by squirting water jets to it. This jet can be up to five metres long, but what is interesting is this jet is squirted with a huge speed so the insect can be killed only by this jet power.  This thing seems to be amazing and easily but, they are encountering an obstacle. 

From water, Archer present two choices: the 'target' which is rewarded and 'distractor' which is not.

When taking aim, the archerfish takes refraction into account ( the way light bends as it enters water). It is able to correct its aim to anticipate a prey's true position, rather than the distracted one from underwater.

So, I think that the fish are smarter than most people realize because they are calculating the angle of their jet with the help of the refraction of the light.
The Archer Fish is considered as the one of the deadliest way to hunt their prey.

I am pasionated about the animals and their talents.
In this blog I will present to you all the wonderful talents that I think most of the people doesn't know them.
