Hi, i recently watched a program on the dicovery channel (Ushuaia
nature) which featured a worm-like creature called "FRESHWATER
BEARCUB" found in the algae in Greenland. can anyone tell me something
about this creature and its nearly transparent anatomy?

I recall seeing something like that on public tv as well. The " water bear"
as it is also known is a protozoan which is microscopic in size, smaller
than 1/16 inch (2mm) . I wish I could help more than that. Interesting
little creatures.

Tardigrads are known as "water bears" and similar common names:

The ones I've seen aren't worm-like, although one saltwater species
I've seen has a long, rod-like body with appendages, rather than the
compact "bearcub" shape often described.
