Three Cheers for the Pom Pom Anemone!

Most of us have seen sea anemones on the rocky shores. But, the pom-pom anemone (Liponema brevicornis) lives unattached on muddy seafloors at depths of 330-3,300 feet. It feeds on food particles drifting by. They have been found near hydrothermal vents and cold seeps as well as near whale carcasses.

The pom-pom anemone can be puffed up like in the top picture, or can flatten out more like a rolled tube. Scientists have seen the anemones in this shape being blown by currents on the sea floor like a tumbleweed. Another common name for this animal is the tumbleweed anemone.  (But, we prefer Pom-Pom). 

HUZZAH!

Scientists at the Monterey Bay Aquarium Research Institute observed sea spiders (pycnogonids) in the deep sea sucking fluids out of the tentacles of pom-pom anemones. And they also saw sea spiders pulling off anemone tentacles and carrying them away.
