If slugs are made up of mostly water, then why do they not freeze in winter temps.?

Answer 1

Put some slugs in the freezer and see what happens. ;-)

I have never seen any slugs crawling around in the snow before ... have you?

Maybe they do freeze, since they seem to disappear in the winter.

The new slugs probably come from last years eggs in the Spring.

From Wikipedia, the free encyclopedia:

"Although some species hibernate underground during the winter in temperate climates, in other species, the adults die in the autumn."

The tolerance of the field slug Deroceras reticulatum to freezing temperatures.

Kingston University, Kingston upon Thames, Surrey KT1 2EE, United Kingdom.

Cold hardiness of ectotherms has been widely studied in arthropods, but there is a more limited literature on the survival of molluscs at low temperatures. A number of intertidal species have been examined in detail, but terrestrial molluscs have largely been overlooked until recently. This paper reports results of laboratory experiments to evaluate the cold hardiness of the terrestrial slug, Deroceras reticulatum. The mean supercooling point (SCP) rose from -4.2 degree C in summer to -3.6 degree C in winter. The SCP that caused 50 percent mortality (LSCP50) remained constant at -4.7 to -4.8 degree C in both seasons, but slugs were able to survive the frozen state for longer in winter (LD50 of 31.8 minutes compared with 17.0 minutes in summer). Slug survival at freezing temperatures was prolonged to at least five hours when placed on a moist, absorbent substrate. D. reticulatum exhibits partial freeze tolerance, with an increased survival in winter. The results are discussed in relation to the natural environment of slugs.

Answer 2

You are made up of 65% water. A tomato is 95% water. I think I read somewhere that animals who live in water have some kind of built-in anti-freeze.

Answer 3

They're made of slime as well, and slime will prevent freezing at winter temperature. They still freeze, but not that quickly.
Same like us too. We have blood to keep our body temperature warm during wintertime. Or else, maybe we would have became ice statues during autumn already!!!

Answer 4

slugs have anti freeze chemical in them. Frogs, some reptiles and fished poses the same chemical as well enabling them to swim in really cold places.

Answer 5

Dont hardship to water. Herbs and perennials have a organic dying off era. They get well and return in the Spring. it ought to be desirable to bypass decrease off the greenery which you have precise now or the plant will positioned too lots power into attempting to maintain those aspects alive. they'll come back of their finished glory while the climate turns heat. those flora are in all probability in a state of dormancy so dont hardship with watering as which will basically ice them and help them to die. basically enable be and nature will awaken them up while the ambience is condusive to awakening. it extremely is advisable to benefit on the cyber web and/or get a e book on the thank you to precise prune the roses.

Answer 6

Humans are made mostly of water (75%). Why do we not freeze?

Answer 7

They are salty, and salt water has a lower freezing point. They do freeze if its cold enough

Answer 8

i really dont know but they shrivel up when you put salt on them I think their slime has a lower freezing rate than water itself

Answer 9

no idea, but good question. i want to know the answer myself.

Answer 10

yes they do....
