The bearded fireworm is a type of marine bristleworm that inhabits the Atlantic Ocean
and Mediterranean Sea. These segmented worms typically live in coral, beneath stones,
or in mud in clear, shallow waters. They can tolerate a wide range of environmental conditions.
Most of their body segments have a pair of appendages called parapodia
that help with locomotion. Their segments allow them to be more mobile by enhancing leverage.
Their body is covered in small bundles of hair-like bristles called setae.
Setae can help with locomotion, digging, anchorage, and protection. The setae are
hollow and contain a chemical that can cause a severe burning sensation when touched.
This is because the bristles penetrate the skin and easily break off. Their gills are
located on the sides of their body. Fireworms feed on many different types of coral.
They will also feed on detritus, or animals like anemones and crustaceans.
When injured, fireworms can regenerate the posterior segments of their body.
They grow up to 12 inches long. Their reproduction is not well studied. However,
it is thought that they reproduce both sexually and asexually. Larvae are thought to be planktonic.
