Slug
Licking, Northwest Style
For every toad-licker, there’s a banana
By Amanda Rust
There are many beautiful attributes to the naturally complex
forests of our Pacific Northwest, but none is quite as interesting
as the banana slug, Oregon's favorite invertebrate.
Banana
slugs are a complex species, as one who has seen “The
Life Story of the Slug” in biology class can tell you.
Contrary to popular belief, a slug is not a snail. They are
very similar, but have one important difference: A snail
has a shell to hide in, a slug does not. This distinction
may seem trivial, but it becomes an important detail in the
following experiment:
The
next time you are hiking about in the forest and come across
a banana slug, sneak up to it and give it a lick. Not just
a touch with the tip of the tongue, but a full-on “puppy
dog happy to see ya” kind of lick. As you watch the
slug shrink away from the sudden stimuli, you will notice
a most remarkable reaction: Your tongue goes numb. The slimy
trail of slug ooze is really the only adaptation for slugs
to have a chance of survival when lapped up by some hungry
animal. Truly biochemistry at its finest.
Note:
This does not hurt the slug. It only spooks it a little.
In no way do I condone slug abuse. Of course, how would you
feel if you were just scooting along the forest floor, minding
your own little slug business, when -- slurp!!! -- you got
licked? So do not do this too many times to one slug. Just
use some common sense.
And
there you have it. So, the next time you are in the wet 'n
wild forests of the Pacific Northwest, bring a friend. Tell
them you want to conduct a “serious biochemistry experiment”
in which you need their full co-operation. The rest is up
to you.
