What is lancelet classification?

CephalochordataLancelet / Scientific name

What group do lancelets belong to?

amphioxus, plural amphioxi, or amphioxuses, also called lancelet, 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.

Is Balanoglossus a Cephalochordata?

Hence option D is correct. Thus, the correct option is Non-Chordata (option D). Additional information: Previously balanoglossus was classified under phylum Hemichordata which was considered as the subphylum under Chordata. But now Hemichordata is considered as a separate phylum under Non-Chordata.

What are the tunicates and lancelets classified as vertebrates chordates?

Lancelets and tunicates are the two groups of invertebrates that belong to the phylum Chordata. They possess the four distinctive features of chordates at some point during their development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. However, they never develop a bony backbone.

What is Branchiostoma lanceolatum?

The mature adult Branchiostoma lanceolatum, aged 2 to 3 years, congregate in masses on the sea floor. Individuals are either male or female and spawn once a year. The eggs are laid and fertilisation takes place externally. The early larval stages take place in the substrate but a little later, the larvae become pelagic.

Geographical Distribution of Branchiostoma: It has almost a cosmopolitan distribution and is found on the sandy shores covering the tidal area to depths of many meters. It is an inhabitant of the shores of tropical and temĀ­perate seas.

What type of vertebrate is a lancelet?

Branchiostoma lanceolatum, the European lancelet or Mediterranean amphioxus, is a lancelet in the subphylum Cephalochordata. It is a marine invertebrate with a notochord but no backbone and is used as a model organism to study the evolutionary development of vertebrates.
