listening to bio webcast on animal forms and function. rather interesting, until the lecturer mentions about how sponges, which live in the sea, get their food:
"the water is seived for nutrients in the seawater. now what stays in this sea water? the sea water, you know when you watch televions and documentaries, are basically blue right? sometimes you can even see the seabed, ok?
but imagine that water to be like soup, full of *pauses for a while* things! microscopic things, moving around. most of the marine animals when they reproduce, they release eggs and sperms. and these fertilize the water and the young, the larva, move ard the water ..."
O.o
erm, ok, thanks for destroying the perfect image of the nice blue sea...
