Pictures of Hudson River Animals, Plants, Algae, More...

The Hudson River Estuary Program has organized pictures of common estuary organisms on sheets of six card-sized images for printing on 8½" x 11" paper. A second page accompanying each set of images has information about the classification, size, habitat, place in food chains, and life cycle of each organism. The two sheets can be printed back-to-back, allowing each picture to be cut out with the appropriate text on its reverse side.

Printed back-to-back, pictures will orient with text on reverse side

With the pictures and information, students can assemble food webs, place organisms in appropriate habitats, and research and write reports, among other activities. The images - from DEC files, online sources, and individuals - may be reproduced for educational purposes. However, other uses of the images may be restricted.

Given space limitations, information about each organism is not exhaustive. Some have very complex life cycles that are sketched out without much detail. Even information that might seem straightforward - facts about a well-known fish's diet, for example - can be complicated as foods eaten change with life stage, size, and prey availability. We have striven for accuracy, but recognize that condensing such material may inadvertently introduce misinformation; we welcome suggestions for improvement from informed readers.

Most organisms are identified down to species; in these cases the organism is known to live in the Hudson. However, some are identified only to the level of genus, a few to the level of order, and one to phylum. While these taxa are found in the estuary, the particular species shown may or may not be present.

More groups of flora and fauna will be added to this collection; visit this website in the future to check out additional images.
