lancelet branchiostoma
Cephalochordata
The lancelet belongs to the subphylum Cephalochordata within the phylum Chordata. They are small, fish-like marine organisms that exhibit characteristics of chordates, such as a notochord and a dorsal nerve cord.
Phylum chordata is divided into three sub-phyla: 1) Urochordata or Tunicata 2) Cephalochordata 3) Vertebrata
Phylum chordata is divided into three sub-phyla: 1) Urochordata or Tunicata 2) Cephalochordata 3) Vertebrata
There are three surviving subphylums of Chordata. The first, which branches off earliest, is called Urochordata and contains tunicates. The other two branches fork later, and are the Cephalochordata (amphioxus/lancelets) and Craniata (all vertebrates).
A vertebrate is a type of chordate. For example In the phylum Chordata they're are three subphyla, Urochordata, Cephalochordata, and Vertebrata. Vertebrates fall in the subphyla Vertebrata.
The three examples of phylum annelida are earthworm,leech and whatever............
Lower chordates refer to a group of simple, marine invertebrate animals that belong to the phylum Chordata but do not possess a backbone or vertebral column. Examples of lower chordates include tunicates, lancelets, and hagfish. They are considered primitive chordates with some characteristics of vertebrates.
Examples of protochordata are Balanoglossus,Herdmania and Amphioxus.
