Lancelet - Wikipedia The term "amphioxus" is still used as a common name along with "lancelet", especially in the English language All extant lancelets are all placed in the family Branchiostomatidae, class Leptocardii, and subphylum Cephalochordata
Amphioxus | Anatomy, Habitat Reproduction | Britannica Amphioxus, any of certain members of the invertebrate subphylum Cephalochordata of the phylum Chordata Amphioxi are small marine animals found widely in the coastal waters of the warmer parts of the world and less commonly in temperate waters
Amphioxus as a model to study the evolution of development in . . . Cephalochordates and tunicates represent the only two groups of invertebrate chordates, and extant cephalochordates – commonly known as amphioxus or lancelets – are considered the best proxy for the chordate ancestor, from which they split around 520 million years ago
The Natural History of Model Organisms: Amphioxus as . . . - eLife Here we describe the life cycle of amphioxus, and discuss the natural histories and habitats of the different species of amphioxus We also describe their use as laboratory animal models, and discuss the techniques that have been developed to study different aspects of amphioxus
Amphioxus as a Model for Understanding the Evolution of . . . Amphioxus was first discovered in Europe as a lancelet Taxonomically, it belongs to the subphylum Cephalochordata, which means “chordate in the head ” The fossil evidence, as well as the modern molecular phylogenetic tree, suggests amphioxus as the most basal chordate
Amphioxus: a rare and valuable marine wild cephalochordate . . . Amphioxus is widely distributed in tropical and temperate shallow seas, especially in coastal areas between 48° north latitude and 40° south latitude, such as the Mediterranean Sea, Malaysia, Japan, and the coast of North America It is found in Xiamen, China, and the South China Sea
