This family has barely been studied on the Great Barrier Reef, even though its looking like the group is a bit more diverse than we thought (more on that coming soon!). There are actually only two species of Haplosplanchnidae reported from the GBR, so this beast makes the third.

I also included the first record for the species Haplosplanchnus pachysomus from Australia in the same paper. Here's a picture of the worm for your admiration:

Parasites are pretty groovy but I'm also a bit of an amateur entomologist, and have published a few short papers and research notes on insects over the last couple years. I just got a short note published in the Australian Entomologist detailing some observations I made of a species of jumping spider, Menemerus bivittatus on the balcony of the old "Queenslander" style home I rented when I first moved to Brisbane. If you don't live in Brisbane, essential background information is that all our homes are infested with these tiny black ants called Technomyrmex sophiae. These critters aren't that much of a problem, and don't really get into your food or anything, but they will build nests in just about any small crevice. They seem to enjoy potted plants the best, but I have personally experienced small colonies living inside the machine bits of a blender, and behind the motherboard of my washing machine. The point here is, they are constantly moving house, and their little wagon trains are great targets for raiders.
Menemerus bivittatus is a pan-tropical species and is pretty common around here in Brisbane. We had them back in Texas as well, which is why they were so easily recognizable to me. Anyway, these spiders have some clever tricks. One such trick is train robbery, stealing the ants' precious larval cargo. The micro-world is a savage one. Check out the video I shot of this behaviour on YouTube.
Be sure to download the paper and give it a read. Heres the citation and a link:
