Does anyone know of a website that provides open source photos of intertidal scenes (perhaps quadrats) where students can ID common intertidal organisms? Asking for curriculum development, thanks!
Iβm trying to make a list of specific species of estuary and intertidal animals in my general area so I can identify them when Iβm at the beach. I also wanna draw some for the heck of it.
The beaches Iβve visited are Singing Beach (MA), Good Harbor (MA), Revere Beach (MA), Wingaersheek Beach (MA), Hampton Beach (NH), Salisbury Beach (MA), Goose Rocks Beach (ME), Rye Beach (NH), Cranes Beach (MA), Plum Island Beach (MA), Half Moon Beach (MA), and Ogunquit Beach (ME).
Sorry if this post is a bit disorganized, itβs my first one
1 and 2: edible crab (cancer pagurus)
3: plumose anemone (metridium senile)
4: sea vase tunicate (ciona intestinalis)
5: shrimp (probably Lebbeus sp.)
6: sea stickleback (spinachia spinachia)
7: european lobster (homarus gammarus)
8: spiny squat lobster (galathea strigosa)

The samples were collected once in three months during 2015 from intertidal zone of Shatt al-Arab River from eight sampling sites. For the purpose of evaluating the spatial and seasonal variations in the diversity, density and abundance of invertebrates in relation to diversity of Aquatic plant and related the dynamics of water temperature, salinity, water transparency, pH, dissolved oxygen, phosphate and nitrate. The diversity and distribution patterns of certain invertebrate's species were clearly related to plants and water quality as evident from the present study.
In the present study tried to assess indices invertebrate species as Shannon-Weaver index, Simpson's index, and Index of Evenness species in eight sites at Shore of Shatt Al- Arab River and predict the state of water according to species and physicochemical parameters. The indices were evaluated at individual species level and varied species to species. In the study 37 invertebrate species from two phylum and five classes were observed. The Annual density of Arthropoda and Mollusca were 61.32% and 38.68% respectively. The class wise densities were as Bivalve (1.22%), Insecta (4.27%), Malacostraca (27.50%), and Maxillopoda (29.52%), Gastropoda (37.46%).

Aquatic invertebrates are important components of aquatic food web. They act as decomposers, detritus, an indicator and primary food for others. Benthic invertebrates have been attractive targets of biological monitoring efforts because they are a diverse group of long-lived, sedentary species that react strongly and often, predictably to human influence on aquatic ecosystems [1]. Macroinvertebrates and water quality are interrelated to each other, as macroinvertebrates are a potential indicator of water quality [2]. They are most frequently used in biomonitoring studies because the responses of macroinvertebrates to organic and inorganic pollution have been extensively documented [3].
A number of studies have compared the ability
