Syllid
Syllidae is a Family (biology), family of small to medium-sized polychaete worms. Syllids are distinguished from other polychaetes by the presence of a muscular region of the anterior digestive tract known as the ''proventricle''. Syllid worms range in size from to . Most syllids are benthic organisms that transition to a pelagic epitoke for reproduction. They are found in all regions of the ocean, from the intertidal zone to the deep sea, and are especially abundant in shallow water. They are found in a range of habitats, moving actively on rock and sandy substrates, hiding in crevices and among seaweeds, and climbing on sponges, corals, hydrozoans, seagrasses and mangroves. They are generalist feeders. A young Syllid was one of the first worms to be found with pollen from seagrass in its stomach, making it a possible pollinator. ''Syllis ramosa'' was the first polychaete discovered to have a branching body plan. Later, two species of Ramisyllis were discovered to have a br ...

Syllis Ramosa
''Syllis ramosa'' is a species of polychaete worm in the family Syllidae. It is found in the deep sea where it lives within the tissues of a sponge. It was the first branching polychaete worm to be discovered, with each worm having a single head and multiple anuses. History During the period 1872 to 1876, the Royal Navy's HMS ''Challenger'' was used in the ''Challenger'' expedition to survey and explore the world's oceans. One of the unknown animals dredged from the ocean depths near the Philippines was a species of sponge which was found to contain numerous branching worms inside its cavities. In 1879, one of these worms was formally described by the Scottish marine biologist William Carmichael McIntosh, who named it ''Syllis ramosa''. Branching polychaete worms were previously unknown. Distribution This bristle worm was first discovered living commensally with a sponge at a depth of about near the Philippines and at a depth of in the Arafura Sea. Further branching worms ...

Epitoke
Epitoky is a process that occurs in many species of polychaete marine worms wherein a sexually immature worm (the atoke) is modified or transformed into a sexually mature worm (the epitoke). Epitokes are pelagic morphs capable of sexual reproduction. Unlike the immature form, which is typically benthic (lives on the bottom), epitokes are specialized for swimming as well as reproducing. The primary benefit to epitoky is increased chances of finding other members of the same species for reproduction. There are two methods in which epitoky can occur: schizogamy and epigamy. Schizogamy Many species go through schizogamy, where the atoke uses asexual reproduction to produce buds from its posterior end. Each bud develops into an epitoke and, once fully formed, will then break off from the atoke and become free-swimming. Many genetically identical epitokes are formed in this way, thus allowing a higher chance of finding a mate of the same species and subsequent passing of genes to th ...
