ICE WORM




I though that worm is only survive in a dry, wet, warm environment, but as I watch this a documentary title, “Extreme Alaska; Denali Park” I found out that worm is exist in this type of environment. This creature called “Icy worm” they look like an earthworm and survive under thick part of glacier ice in Alaska They can also found in Washington, Britain Columbia, and Oregon and any glacier part of the world. Their survival depends on their environmental temperature. Ice worms retreat underneath the ice before dawn Enzyme in ice worms have very low optimal temperatures, and can be denatured at even a few degrees above 0 degree C . When ice worms are exposed to temperatures as low as 5°C, their membranes melt and the worm itself liquefies. Ice grows several centimeters long, and they can be black, brown, and white in color. These creature has maladaptive behavior in terms of temperature, I hope they will flourish and still protected despite of the danger effect of global warming.
