Field Notes

Description:

Crayfish – also called crawfish or crawdads – are freshwater crustaceans resembling small lobsters. They breathe through feather-like gills and are found in bodies of water that do not freeze to the bottom. They are mostly found in brooks and streams where there is fresh water running, and which have shelter against predators. Most crayfish cannot tolerate polluted water.

Habitat:

The Martyn Trail is a 1.22 mile loop through heavily forested wetlands.

Notes:

Upper Texas Coast (UTC 081) ARMAND BAYOU NATURE CENTER: A system of nature trails honeycombs the property, and the center operates a pontoon boat that plies the waters of Armand Bayou. ABNC staff and volunteers have spent countless hours restoring several hundred acres of coastal prairie, and grassland species such as Sedge Wren and Le Conte’s Sparrow are not difficult to find here. ABNC staff is available to answer questions about when and where to bird in the Clear Lake area.

I love to point these out to children and where there are chimneys there are raccoon prints. Here is a fun article for you from Loyola; http://loyno.edu/lucec/natural-history-writings/crawfish-and-their-chimneys
I've seen these before in Georgia, but never knew what made them. I incorrectly assumed some type of snake. I learn something new regularly on Project Noah.
