“…Benthic Chaetopterus make light using a unique photoprotein (Shimomura 2006) five times as large as cnidarian photoproteins. Luminescence is also present in a recently discovered planktonic species of Chaetopterus (Osborn & Rouse 2008).…”

“…Haddock, unpublished data), and a newly discovered group of deep-sea polychaetes carries luminescent "bombs" that it drops when disturbed (Osborn et al 2009). These are families in which planktonic existence is a derived trait (Osborn & Rouse 2008), suggesting another independent origin of luminescence correlated with animals moving up into the water column.…”

Bioluminescence spans all oceanic dimensions and has evolved many times--from bacteria to fish--to powerfully influence behavioral and ecosystem dynamics. New methods and technology have brought great advances in understanding of the molecular basis of bioluminescence, its physiological control, and its significance in marine communities. Novel tools derived from understanding the chemistry of natural light-producing molecules have led to countless valuable applications, culminating recently in a related Nobel Prize. Marine organisms utilize bioluminescence for vital functions ranging from defense to reproduction. To understand these interactions and the distributions of luminous organisms, new instruments and platforms allow observations on individual to oceanographic scales. This review explores recent advances, including the chemical and molecular, phylogenetic and functional, community and oceanographic aspects of bioluminescence.

“…Namely, families that are considered aberrant, specialized, or of limited diversity, and are difficult to place in phylogenetic trees based on morphology, are often nested within larger well-recognized annelid families. Examples of this include Flotidae, Poeobidae and Pisionidae (Burnette et al 2005;Struck et al 2005;Wiklund et al 2005;Osborn & Rouse 2008). However, arguably we need better taxon and gene sampling to illustrate fully this point with the taxa examined here.…”

Struck, T. H. & Halanych, K. M. (2010). Origins of holopelagic Typhloscolecidae and Lopadorhynchidae within Phyllodocidae (Phyllodocida, Annelida).-Zoologica Scripta, 39, 269-275. Several distinct lineages of annelids have evolved holopelagic life styles. Unfortunately, our knowledge of the biology and evolution of most of these groups is limited. Typhloscolecidae and Lopadorhynchidae are two such examples of recognized families of holopelagic annelids about which little is known.Both groups have a limited number of known species (13 and 15, respectively) and are rarely discussed in the literature other than to note occurrence. Placing these groups in a phylogenetic context has been difficult due to their seemingly unique morphology, and, to the best of our knowledge, lack of molecular data. Nonetheless, previous authors have suspected that they are members of Phyllodocida and perhaps within Phyllodocidae. To test such hypotheses, we have employed nuclear 18S and 28S ribosomal data in both a Bayesian inference and a maximum-likelihood framework. The resultant topology indicates that typhloscolecids and lopadorhynchs are sister taxa nested within Phyllodocidae near another holopelagic taxon, alciopids. Whereas posterior probabilities strongly support this placement, an AU hypothesis testing approach and bootstrap values are more equivocal but both still strongly suggest Phyllodocidae affiliations. Recognition of Typhloscolecidae and Lopadorhynchidae as annelid families is called into question.

“…Phylogenetic analyses of Flabelligeridae were conducted several times by using morphological and molecular data sets (Burnette et al 2005; Osborn and Rouse 2008; 2011; Salazar-Vallejo et al 2008). A morphological analysis suggested that Trophoniella was similar to Piromis .…”

Trophoniella hephaistos sp. n. was collected from a tank irrigated with seawater pumped directly from Nabeta Bay, Japan. This species is discriminated from other Trophoniella by having dorsal tubercles, a tongue-shaped branchial plate, a tunic covered with large sediment grains dorsally and ventrally, having eyes, and anchylosed neurohooks starting from chaetigers 17–20. This is the first record of Trophoniella from Japanese waters. Identification keys to species of Trophoniella and four gene sequences (COI, 16S, 18S, 28S) of this species are provided. Phylogenetic analysis was conducted to clarify phylogenetic position of Trophoniella in Flabelligeridae using four genes.
