On the lancelets of West Africa.
Proceedings of the Zoological Society of London, 1955 SUMMARY. During 1948–1952 a large number of small terrestial mammals were collected in connexion with Scrub‐Typhus investigations. Simple standard data of weight and state of fertility of these animals were kept, and the results are summarized in table 15. With a few exceptions, the sex ratio approximated to equality.

Filter Feeding in Lancelets (Amphioxus), Branchiostoma lanceolatum
Invertebrate Biology, 1999 Little work has been done to describe lancelets as filter feeders, and hitherto no data have existed on either filtration rates or the efficiency with which food particles are retained in the filters. The aim of the present work was to describe and characterize Branchiostoma lanceolatum as a true filter-feeding species. The clearance-rate capacity in B.

Putative extremely high rate of proteome innovation in lancelets might be explained by high rate of gene prediction errors [PDF]
Scientific Reports, 2016 A recent analysis of the genomes of Chinese and Florida lancelets has concluded that the rate of creation of novel protein domain combinations is orders of magnitude greater in lancelets than in other metazoa and it was suggested that continuous activity

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2007 The lancelet is considered to be a promising laboratory model animal. To establish laboratory colonies of lancelet, we collected parental lancelets of Branchiostoma belcheri and B. japonicum (previously named as B.

Zoological Science, 2006 Lancelets in Xiamen were reported as Branchiostoma beicheri in 1932, and subsequently were believed to comprise a single species. However, recent studies revealed that Xiamen lancelets actually represent two species, B. belcheri and B. japonicum.

A Taxonomic Review of Lancelets (Cephalochordata) in Japanese Waters
, 2016 Until the 1980s, the Japanese lancelet fauna had been believed to contain a single species, but now the number of species becomes six in total, covering all the three known genera: Branchiostoma japonicum (Willey, 1897); Asymmetron lucayanum Andrews, 1893 complex spp. A and B; A. inferum Nishikawa, 2004; Epigonichthys maldivensis (Cooper, 1903); and E.
