Amphiodia pulchella is a species of brittle star belonging to Amphiuridae, a diverse family of the Ophiurida order.

[3] Amphiodia pulchella are typically a gray or reddish brown color with fine scales covering the central disc.

Ophiuroidea are also unique compared to other echinoderms because they have a smaller coelom and a nerve ring in the central disc that is connected to each arm.

Climate change, which is mostly a result of human activity releasing green house gases into the atmosphere, is causing ocean water to increase in acidity.

Brittle stars are producing shells at a greater rate to protect their delicate arms from being compromised by acidic water while they are burrowed.

[8] Oocytes 0.65mm in diameter suggest that A.pulchella have a planktonic, feeding larval stage and do not rely on yolk reserves for development.

Geographically, this species can be found in the Western Central Atlantic including the coasts of Florida, Mexico, Cuba, Jamaica, Puerto Rico, Tobago, Belize, Brazil, and Argentina.
