Occurrence of the New Zealand lancelet in the plankton

New Zealand Journal of Marine and Freshwater Research, 1979
Fourteen specimens of the New Zealand lancelet, Epigonichthys hectori (Benham), were taken in two oblique plankton hauls worked after dark on 4 February 1978 off the west side of Great Barrier Island.

Heteropleuron hectori, the New Zealand Lancelet

Journal of Cell Science, 1901
ABSTRACT By the kindness of Sir James Hector I have been able to examine a couple of specimens of an “Amphioxus” that have been for some years past in the Colonial Museum at Wellington, N.Z. The specimens are referred to by Captain Hutton in his ‘Catalogue of the Fishes of New Zealand,’ published by the Colonial Museum and Geological ...

Occurrence of the Lancelet in Haifa Bay, Israel

Nature, 1954
A SPECIMEN of Branchiostoma lanceolatum (Pallas) was collected during the September 1953 cruise of the research vessel of the Sea Fisheries Research Station at a position at 32° 53′ 36″ N., 35° 1′ E., in Haifa Bay at the depth of 15 fathoms. Another station in the eastern Mediterranean has thus been added to the zoogeographical distribution of the ...

Establishment of left‐right asymmetric innervation in the lancelet oral region

Journal of Comparative Neurology, 2001
AbstractLancelets (amphioxus) exhibit a remarkable asymmetric development in the anterior body region, which is reflected in the peripheral nervous system even at adulthood. Not all of the anterior nerves are involved, but the left third to fifth nerves are clearly asymmetric.

A model of antagonistic triarticular muscle mechanism for lancelet robot

2010 11th IEEE International Workshop on Advanced Motion Control (AMC), 2010
This paper describes the development of a robot simulating a lancelet, a chordate often treated as a surrogate for the ancestor of the vertebrate. Although a lancelet has primitive neural circuits, it accomplishes dexterous swimming motion. Hence this study attempts to imitate the swimming motion with simple control architecture and investigate the ...

Population Dynamics of Lancelet Branchiostoma japonicum in the Seto Inland Sea, Japan

Zoological Science, 2020
The population dynamics of lancelet Branchiostoma japonicum are reported for six sampling sites in the Seto Inland Sea, Japan, for November 2007-2016. Lancelet growth and life span varied spatially, being faster and shorter, respectively, at Stn 3 (off Marugame, western Bisan-seto) than at other sites; average body length at Stn 3 was 36.1 mm for 2 ...

Larval Locomotion of the Lancelet Branchiostoma Floridae

Journal of Experimental Biology, 1997
ABSTRACT The ontogeny of locomotion in the Florida lancelet (Branchiostoma floridae) is described for the early developmental stages through to metamorphosis. Recently hatched larvae swam at speeds up to 1 mm s−1 using their epidermal cilia; this speed decreased to approximately 0.2 mm s−1 by 60 h after fertilization.

[Discovery and early studies of the lancelet "Amphioxus"].

Svensk medicinhistorisk tidskrift, 2007
The paper describes the discovery and early studies of the lancelet, "Amphioxus", (Brachiostoma lanceolatus). It became very popular as a scientific object in the 19th century as it was supposed to be a link between vertebrates and invertebrates. Most of the early investigators belonged to the medical profession. In Sweden still a freshmen in a medical
