We study the development and evolution of mineralized tissue in echinoderms.

The Devonian is often appropriately called the «Age of Fishes», since the fish took their place in complex reef systems containing nautiloids, corals, graptolites, blastods, echinoderms, trilobites, sponges, brachiopods and conodonts.

Consider stocking at least a few representatives from each of the following groups: Sponges — many types, shapes, sizes and colors Zoanthids — colonial anemones (some can be harmful to true corals) Anemones — short tentacle, long tentacle and carpet Corallimorphs — mushroom anemones, Ricordea, Discosoma and elephant - ear Cerianthids — tube - dwelling anemones Mollusks (with and without shell)-- sea slugs, sea hares, nudibranches, turbo snails and many types of living shells and clams Cephalopods — octopus and cuttlefish Worms — feather dusters Arthropods — crabs, hermit crabs, shrimp and lobsters Echinoderms — sea urchins, sea cucumbers, sea stars (starfish), serpent stars and brittle stars.

Experiments on echinoderms, for example, show great sensitivity of reproductive success on ocean chemistry changes but we do not know the potential for micro-evolutionary adaptation.

Both echinoderms (the fabulous phylum that includes starfish, sea urchins, brittle stars, and sea cucumbers) share many of the same habitats and thus frequently meet up.

The acidification of oceans may well be the most insidious and pervasive threat to life in the oceans everywhere, simply because so many different plants and animals that play key roles in ecosystems will likely be affected — coccolithophores, pteropods, corals, mollusks (clams, mussels, oysters, snails), echinoderms (urchins, seastars), arthropods (lobsters, crabs, shrimp), etc., etc..

Because if not, «Laboratory experiments revealed that ocean acidification has negative impacts on the fertilization, cleavage, larva, settlement and reproductive stages of several marine calcifiers, including echinoderm, bivalve, coral and crustacean species.

Taxa such as mollusks and echinoderms are well represented within existing datasets with high numbers of georeferenced records.

We have investigated the response of a coral reef community dominated by scleractinian corals, but also including other calcifying organisms such as calcareous algae, crustaceans, gastropods and echinoderms, and kept in an open - top mesocosm [note: a «mesocosm» is an aquarium].

We have investigated the response of a coral reef community dominated by scleractinian corals, but also including other calcifying organisms such as calcareous algae, crustaceans, gastropods and echinoderms, and kept in an open - top mesocosm.

Echinoderms take calcium carbonate out of the seawater and use it to make their internal and external skeletons.

They estimated that about 90 % of species of foraminiferans, sponges, bryozoans, mollusks, and echinoderms are known, whereas turbellarians, nematodes, scyphomedusae, ascidians, and ostracods are particularly poorly studied.

A recent meta - analysis indicated a significant negative effect of ocean acidification on calcifying and non-calcifying echinoderm larvae (n = 26 studies)[63].

Elevated water temperature and carbon dioxide concentration increase the growth of a keystone echinoderm

The Mg - calcite composition of antarctic echinoderms: important implications for predicting the impacts of ocean acidification

Predictions concerning the consequences of the oceanic uptake of increasing atmospheric carbon dioxide (CO2) have been primarily occupied with the effects of ocean acidification on calcifying organisms, particularly those critical to the formation of habitats (e.g. coral reefs) or their maintenance (e.g. grazing echinoderms).

This may impact a wide range of organisms and ecosystems (e.g., coral reefs, Box 4.4, reviewed by Raven et al., 2005), including juvenile planktonic, as well as adult, forms of benthic calcifying organisms (e.g., echinoderms, gastropods and shellfish), and will affect their recruitment (reviewed by Turley et al., 2006).
