Pseudoliparis swirei is the deepest-dwelling fish in the world. This small deep sea creature can withstand more water pressure than 1,600 elephants standing on its head. Researchers exploring the Mariana Trench, the deepest place on Earth, found large numbers of weird, tadpole-like fish swarming their mackerel-baited traps.


This translucent snailfish was recorded 5 miles below the surface of the ocean, making it the deepest-dwelling fish in the world. This is a tadpole-like fish measuring 112 mm yet appears to be the top predator in its benthic community at the bottom of this particularly deep sea. P. swirei belongs to the snailfish family, Liparidae. It is believed that 8,200m is a physiological limit below which nearly no fishes can survive.

What makes poison dart frog resistant to their on poison?

These animals are endemic to the Pacific coast of Colombia. An average one milligram of poison available in one frog is enough to kill 10-20 humans [1] . Indigenous people carefully expose the frog to the heat of a fire, and the frog exudes small amounts of poisonous fluid. The tips of arrows and darts are soaked in the fluid. Their deadly effect kept for over two years [2] . The interesting question is, what makes the frog itself resistant to this deadly poison! How is the toxin produced? These animals store Batrachotoxin, a steroidal alkaloid toxin in their skin gla...

Bat-roost? To curb malaria!

This article was originally posted at Amazing Zoology . View original article at https://amazingzoology.com/bat-roost-curb-malaria/ 110 years ago, one man set out to rid Texas of Malaria – with the help of what was then a very unlikely source… bats! Dr. Charles A. Campbell had a simple plan. He knew that bats eat mosquitoes, and believed that if he could entice thousands of bats to live in Malaria-ridden areas, they would single-wingedly eradicate the disease. After years of fruitless experimentation with small roosting boxe s, he decided to go BIG, with a 30-foot tower containing roosting shelves, guano lures, and a meal plan – three large hams! The $500 contraption was, alas, a flop. Campbell realized that he didn’t understand bats enough to provide suitable homes. He spent months studying caves and roosts to learn what bats needed most. In 1911 he constructed a new, improved tower at Mitchell’s Lake, where 90% of the locals were sick with Malaria. Within...

Blood Clot Coloured scanning electron micrograph (SEM) of red blood cells (erythrocytes) trapped in a fibrin mesh (yellow). The production of fibrin is triggered by cells called platelets, activated when a blood vessel is damaged. The fibrin binds the various blood cells together, forming a solid structure called a blood clot. A blood clot is a normal response, preventing an excessive loss of blood. However, inappropriate clotting is a major cause of heart attacks and strokes. Red Blood Cells (RBC) They look like little cinnamon candies here, but they are actually the most common type of blood cell in the human body – red blood cells (RBCs). These biconcave-shaped cells have the tall task of carrying oxygen to our entire body; in women there are about 4 to 5 million RBCs per micro liter (cubic...
