According tomedia reports, in the animal kingdom, if you are eaten it usually proves that you are done. But if you’re a Regimbartia attenuata — a beetle that doesn’t want to be swallowed — then this rule won’t work for you. The beetle has an incredible ability to escape, according to a new study published in The Current Biology.
It is understood that the beetle crawls past the predator after being swallowed — usually the frog’s internal organs, which prompts the latter to excrete it through excretion.
The study’s researcher, Dr. Shinji Sugiura, wanted to see how beetles and frogs get along. It is reported that the two species in the study were found in Japan and inhabited in the same place, so scientists took them back to the lab and put them together to see what would happen. The expected result is that the frog eats the worm and then digests it normally or spits it out — at this point because the insect has good defenses or doesn’t taste good for the predator.
The two species can be seen meeting in transparent plastic boxes. Unsurprisingly, the frog swallowed the worm, but didn’t spit it out. Still, Dr. Sugiura continued to drive the camera, to his surprise, and about two hours later, the insect escaped from its predator’s intestines. The beetle crawled out of the other end of the frog and was as vibrant as it had just come in.
The story doesn’t seem to be strange enough, because the frog doesn’t seem to mind what’s going on, not even noticed that its last meal of “food” is safe.
Considering that it might be some kind of strange luck, Dr. Sugiura decided to repeat the experiment with more frogs and beetles. Time and again, the beetles were eaten but within about six hours they were drilled out of the back of the attacker’s buttocks. Ninety per cent of these beetles survive, and although the success rate is not 100 per cent, it is already quite close.
When a different species of beetle were used in the experiment, they died, suggesting that the shell of this particular species must have something incredibly special. To see if the bugs actually crawled inside frogs, Dr. Sugiura fixed some of them and let them eat them. None of these beetles escaped, which seems to prove that they are actually venturing through the frog’s internal organs to speed up their escape.
