Comments by A Faucci (Apr 13):

• Great work overall!
• Make sure you integrate the text that is already on Wikipedia with your additional information so that it makes sense and there is not too much overlap. For example, I would keep general non-specific brief things in the lead and then more specific stuff in the subsections. For example, move the "Carpilius convexus are yellow-brown or red, ...." under Description and then add the part about "The Biology of the genus is poorly know" or delete that sentence alltogether, before adding your biology. i would change the section title to Description and Biology and maybe also include the part on mating behavior.
• Nice work in finding good references. Make sure that you use the "cite function above to cite your references in the text. Each sentence or statement should be linked to a reference in that way. Check the training on Wikipedia on how to cite or the videos on the LibGuide. Otherwise reach out if you need help on how to do that properly.
• Make sure to read your text out loud one more time to catch any English or flow issues. Make sure to be very concise and eliminate any duplication of information.

Article Draft

Lead (Untouched)

Carpilius convexus is a species of crab that lives in the Indo-Pacific, from Hawaii to the Red Sea and South Africa. It was first described by Peter Forsskål in 1775 as "Cancer convexus", and has sometimes been treated as a variety of the larger species Carpilius maculatus. The biology of the genus Carpilius is poorly known. A Carpilius convexus coloration is a yellow-brown or red, with patches that are mainly brown, growing up to 25 cm. Despite us knowing their size, coloration, and habitat, little is known about their biology till this day.

Description

Carpilius convexus are a poisonous species of crab, causing twitching and muscle spasms in mice lasting 30 minutes or more. They feed on bivalve mollusks such as clams, oysters, and mussels. Also prey on tridacnids like giant clams.

Distribution

In addition to the areas previously listed, convex crabs are also found in the South China Sea, Arabian Gulf, and even reaching the coasts of Japan and Australia.

Habitat

They are usually found on rocky outcrops or coral reefs and are nocturnal, which may be the reason they are not often found. They dwell between the intertidal zone and depths of 35 meters, taking shelter in and under rocks or plant life.

Mating Behavior

Convex crabs are part of the order Decapoda, which are mostly gonochoric. Mating behavior consists of pre copulatory courtship ritual followed by indirect transfer of sperm.

Human Use

At this time, convex crabs are not used for much by humans. The only known economic value of these creatures is aquarium trade, putting these arthropods on display. They are found to be mildly toxic and unsafe for human consumption so food use is questionable.
