New findings about animals in 2013
Praying Mantis prey by the shape of flowers, climbing fish or butterflies drinking turtle tears are novel features of animals discovered and studied in 2013.
1. Fish climbing waterfall
Nopoli climbing fish (Sicyopterus stimpsoni) found in Hawaii, USA, is a species capable of climbing waterfalls with a height of 100 m, using the mouth sucking. (Photo: Live Science)
2. Embryonic sharks know how to detect enemies
Embryo fetal sharks have the ability to sense predators' electric fields and freeze in place to avoid detection and reduce the risk of being caught. (Photo: mnm.com)
3. Tadpoles have eyes on the tail
In February of this year, the researchers successfully implanted the eye on the tail and trunk, instead of implanting the head and the tadpole of Xenopus laevis frog, then removing the original eye. According to the researchers, eye-implanted tadpoles in these parts are visible. (Photo: Live Science)
4. Spiders eat bats
Research results in March showed that spiders like Argiope savignyi or African black spider Poecilotheria rufilata, present in continents around the world, are species that often eat bats in tropical regions of the world. The sight of bat-eating spiders was not observed in Antarctica. (Photo: Live Science)
5. The shark has two heads
A fisherman caught a pregnant shark shark near the Florida Keys limestone archipelago, and discovered a two-headed shark fetus after a maternal fish operation. According to the researchers, this is the only two-headed cow shark fetus they have ever known. (Photo: Bussiness Insider)
6. Giant Python swallow monkey
For the first time, researchers witnessed a giant python attacking and swallowing a howling monkey in the Amazon, Brazil forest. The monkey strayed from the flock, did not detect the presence of the python and was swallowed up shortly thereafter. (Photo: Live Science)
7. Butterfly drinking turtle tears
Brightly colored butterflies live in the Peruvian Amazon forest, often surrounding turtles for tears. Turtle tortoises contain salt, especially sodium, a rare mineral in western Amazon, so turtle tears become very valuable to butterflies. Meanwhile, tearing is a way for turtles to excrete salt from their bodies and butterflies can help them when they cannot wipe their own tears. (Photo: Peru Nature)
8. Praying Mantis prey with a flower-like shape
According to scientists' research, a flower-like appearance not only helps orchids attract and distract their prey, but also avoids the risk of being attacked by other animals. Orchid mantis is considered to be one of the best camouflage species in the animal world. (Photo: Live Science)
9. Cockroach species can tolerate cold
Cockroach species that are cold-tolerant and able to survive in snow are discovered in New York, USA. They have the scientific name of Periplaneta japonica. According to the researchers, cockroach eggs may have been mixed in soil in bonsai pots when taken back to America. (Photo: mnm.com)
10. The trick of hunting crocodiles
Research by American scientists shows that alligators, known as swamp hunting assassins, know how to use small branches as bait tools, making it easier to catch prey. (Photo: Nature World News)
