AIR FURNACE FILTER

If you're not, I'll send this creature to your house! ;)

Okay, so it's an entirely harmless fan shrimp that doesn't even have any pincers (they filter feed with their "fans") and is roughly 3" long. Still, I think she looks quite frightening. This is my female, and she has eggs, but the larvae will not survive because they need salt water. The white dots aren't tank-that-needs-cleaning, they're Hikari First Bites™ fry food; I give that to them sometimes because they can eat only small particles, and they really love the stuff.

Note to the pet store employee who said they're bamboo shrimp because "they eat bamboo." Uhhh...no. :)

Sea anemones are a group of water dwelling, filter feeding animals of the order Actiniaria; they are named after the anemone, a terrestrial flower. As cnidarians, sea anemones are closely related to corals, jellyfish, tube-dwelling anemones and Hydra.

Sea urchins are small spiny sea creatures of the class Echinoidea found in oceans all over the world. Their shell, which is also called the test, is globular in shape and covered with spines.
