It is shown that the large patellazoles biosynthetic pathway is maintained, whereas the remainder of the genome is undergoing extensive streamlining to eliminate unneeded genes.

The new species of Zanclea sango sp. nov. is described from Okinawajima Island, Ryukyu Archipelago, south-western Japan. The new hydrozoan species is associated with at least three scleractinian…
Allorecognition in compound ascidians.
The fusibility locus of botryllids seems to be very similar to the MHC of vertebrates, considering that vertebrates evolved directly from ascidians, it is likely that the fusible locus is an ancestral form of the vertebrate MHC.
Ascidian tunic cells: morphology and functional diversity of free cells outside the epidermis

In some ascidians, phagocytic cells are involved in other functions, such as pigmentation, intracellular photosymbiosis, and bioluminescence, suggesting that tunic cells have a high potential to diversify and evolve a wide variety of cellular functions.
Domination and disappearance of the black sponge: a quarter century after the initial Terpios outbreak in southern Japan.
Preliminary results suggest that T. hoshinota outbreaks, although very destructive, may be sporadic in nature, and not always an irreversible“climax” for affected reefs.
Multiple origins of the ascidian-Prochloron symbiosis: molecular phylogeny of photosymbiotic and non-symbiotic colonial ascidians inferred from 18S rDNA sequences.
Complete nucleotide sequences of mitochondrial genomes of two solitary entoprocts, Loxocorone allax and Loxosomella aloxiata: implications for lophotrochozoan phylogeny.

The results show that identification of the disparate darkly pigmented species has been difficult, and that several reports of P. nigra are likely either P. fumigata or P. philippinensis, and an effort is made to have ranges and potential invasions corrected in the ascidian literature.
Algivore or Phototroph? Plakobranchus ocellatus (Gastropoda) Continuously Acquires Kleptoplasts and Nutrition from Multiple Algal Species in Nature
The results suggest that natural populations of P. ocellatus do not rely on photosynthesis but mainly on the digestion of ingested algae, and that kleptoplast photosynthates form a significant source of nutrition for starved sea slugs.

The genetic diversity of the genus Prochloron is investigated by constructing a phylogenetic tree based on the 16S rRNA gene sequences of 27 isolates from 11 species of didemnid ascidians collected from Japan, Australia and the USA, and implications for the evolutionary relationship of prochlorophytes, cyanobacteria and chloroplasts are discussed.
