Leech?
June 9, 2010
Here is a leech (I think) that I see fairly frequently at my property in “cloud forest” at 2100m on the eastern slope of the Western Cordilla in Valle De Cauca. It´s about 9cm long. Can you identify it for me?

Leech or PLanarian?

Dear Pitter,
We are very excited to have received your letter, because it represents the first posting to our site for a Leech.  We did some research, and Leeches are actually considered to be Worms, and according to the Australian Museum website, they belong to the same class as earthworms, Clitellata.  You may also find information on Wikipedia.  Alas, we do not have the necessary knowledge to further classify your particular Leech.

Terrestrial Planarian

Hi Goree,
Your photo is the second Terrestrial Planarian we received today, the other being a different species from Japan.  Your specimen most closely resembles Bipalium rauchi which is pictured on the Terrestrial Planaria website.  There is also a YouTube video that looks quite similar.

Damp terrestrial arrowhead flatworm
April 29, 2010
I came across this flatworm under a moist slab of wood in my backyard garden. The flatworm has a head that resembles a fan at times and at other times an arrowhead. The tail anchored the flatworm to the moist wood, although this flatworm was pretty much curled and very mucusy. Along with this flatworm were orange winged beetles resembling ladybugs the size of peppercorn kernels and sow bugs under the wood slab. The dorsal side of the flatworm were 2 outer broad dark stripes (running from head to tail) with a thinner light dark stripe between and parallel to the 2 broad stripes. The underside was basically pale. There was only one flatworm not a community of them. For April it has been raining a bit more than usual, and the garden ground is a bit moist making it easier to pluck out unwanted baby weeds. I was just curious to see what community lived under this particular slab of wood.
My question is what type of flatworm is this?

Hi Lucy,
Thank you for including the detailed information about the community you found under the slab of wood.  We do not have the necessary skills to identify what species of Planarian you have discovered.  It is very possible that it is a young Arrowhead Flatworm, Bipalium kewense, which can grow to ten inches in length.  The markings are consistent with that species.  The Texas Master Gardener website has a nice page on the Land Planarian.  The Featured Creatures website has a great page on the Land Planarian.

Unknown Aquarium Worms

Hi Sean,
Your aquarium is freshwater and we don’t know if it has plants.  We also don’t know where the sand came from or if there are snails present.  We also don’t know how long the tank has been established, when the worms first appeared, or if there have been any recent introductions to the aquarium.  An aquarium is a closed system, and anything in the aquarium is introduced when things (including plants, animals, furnishings or water) are added by the aquarist, and sometimes organisms may be introduced because they are airborne.  Worms are interesting creatures.  They sometimes develop from encysted larvae like the Gordian Worm or Horsehair Worm.  The North Dakota Department of Entomology website has a good explanation of this phenomenon.  Some parasitic worms prey upon snails, and it is possible that your worms were introduced with snails.  We don’t have a conclusive answer for you, but we will continue to research this topic.

We had some additional thoughts.  You may want to collect a sample and try to have it identified.  You can try Nathalie at Pasadena Tropical Fish on Colorado Boulevard.  If that fails, the Natural History Museum in Exposition Park may be able to answer your questions.  Since your email indicates that they are free-swimming, they may also be the larvae of some species of fly.  They may also be Planaria.  See the AquariumFish website for additional information.

Pink Spotted Earthworm?
March 4, 2010
I hope you can help us identify this unusual worm my husband discovered today while trying to photograph a mole! I didn’t see the worm, but he took several photos and after a brief internet search we’re stumped (not that we would expect otherwise, being that we’re *not* experts!). Is it just a regular earthworm with some kind of disease?

Worm

Hi Meg,
The worm in your photo is sure crazy looking.  We cannot say if it is diseased or an unusual species without doing research on the matter, and our time at the moment is limited by other obligations.  We hope by posting this quickly, someone will be able to provide us with an answer.
