Frogs Mating Call Betrays Their Location to Predatory Bats

 Frogs Mating Call Betrays Their Location to Predatory Bats

Frogs mating call betrays their location to predatory bats, researchers from the Smithsonian Tropical Research Institute, Leiden University, The University of Texas, and Salisbury University have discovered. Tungara frogs live in Central and South America, inhabiting shallow puddles. They croak out mating calls to find mates, and although it’s hard to predict if any females will be interested, the male frogs often get more than they bargained for. Predatory bats fly the skies above the frogs and often dive down to snatch them from their puddle homes. Although the frogs have learned and evolved to detect the silhouettes of bats flying over head and stop their call to avoid being spotted, the bats have countered by beginning to use the ripples in the puddle caused by the calling to find and eat the frog even after they have gone silent.

Although the ripples often cause an end to the frog, research showed that it was not without a benefit. The Tungara frogs mating call that betrays their location to predatory bats includes two parts, a whine part and a chuk part. The whine is the part that attracts females, but the chuk makes the call more desirable. The frog makes the call by inflating and deflating a sac of skin on its neck, and its this that causes the ripples. The chuck is specifically responsible for making the ripples around the frog as it sits in the water, turning looking for a date into a gamble between finding love and being dinner. Although the bats can hear the frogs and find them without the help of the ripples, tests showed bats descending on frogs in rippling puddles nearly 40 percent more often still water. Researchers are theorizing that bats are able to use their echo-location abilities to see the ripples as a bull’s eye around the frog that has gone silent. Although they are using their only known trick to avoid detection, the Tungara is betrayed by the slow to stop ripples. Even though it has gone silent, the frog is a clear target to a bat using the ripples as a marker.

Mike Ryan, a researcher at UT Austin, points out that the frogs unfortunate scenario is chock full of information useful to us as well. Pointing out that all methods of communication create a disturbance in the environment, be they calls or lights or smells. Although the frogs are all aware of the air pressure changes interpreted as sound, they are not paying attention to the ripples caused in the water around them. This is what the bats have learned to monopolize on, as they often lose the frog when searching with sound alone, since the frog stops calling as soon as it sees the bat. Since the ripples caused by the frogs mating call betrays their location to predatory bats, Tungaras find themselves in a very difficult situation. Looking at this way, what’s a frog to do when confronted with the choice of mating or being eaten by a giant bat?

    Hey, how’s it going?

    Did you hear that the powers that run this world want to put a RFID microchip in our body? It will contain not only our bank accounts but our personal information, making us total slaves to the elite. This will cause us to lose even more of our privacy.

    Did you know that this RFID microchip matches perfectly with the Mark of the Beast in the Bible, more specifically Revelation 13:16-18?

    “He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name…”

    Referring to the last days, this could only be speaking of a cashless society, which we have yet to see, but are heading towards. Otherwise, we could still buy or sell without the mark amongst others if physical money was still currency. It’s amazing that the Bible foretold a cashless society!

    Did you also hear that the Jewish people are in the process of bringing about the Third Temple prophesied in the Bible by the prophet Daniel, Jesus, and Apostle Paul? They deny Jesus as their Messiah and say their Messiah will be revealed to rule the whole world under a one world religion. They are not even hiding this information, but are actually promoting it. You can view videos about this on YouTube.

    When Donald Trump made Jerusalem captial of Israel in late December 2017, the Jewish people said this was a big step for them to build this Third Temple. They even printed a Temple coin with president Trump’s face on the front with king Cyrus'(the man who built the Second Temple in the Bible) face behind him. On the back of the coin is an image of the Third Temple. They are selling these coins to raise money to build the Temple.

    People have been saying for many years that the end is near, but we needed not only the Third Temple, but also the technology for there to be a cashless society for the Mark of the Beast to be a reality.

    There is much more to know, please visit http://WWW.BIBLEFREEDOM.COM to see all the proof!
