Distribution and Abundance of Amphioxus With Relation To SedimentCharacteristics from South East Coast of India

omicsonline.org  Biodiversity, the variety of life and understood of species survive. Lancelet plays an important role in marine benthic food chain. A study was carried out to observe the abundance and diversity of marine bottom lancelet and observations on sediment characteristics. The lancelet were collected station 1 at Cooum the maximum of 98.12 No/ m2 was observed in site IV and minimum of 4.22 No/m2 was observed in site II. Station 2 at Muttukadu the maximum of 165.12 No/m2 was observed in site I and minimum of 1.10 No/m2 was observed in site IV. Station 3 at Pondicherry the maximum of 98.8 No/m2 was recorded in site II and minimum of 2.35 No/m2 was recorded in site IV. At all station when compared the maximum species was observed in Muttukadu and minimum in Cooum during the study period.
