Morphometric relationship of Lingula larvae collected from the Arabian Sea

Morphometric studies were made on Lingula larvae collected from three different stations off Karwar and Coondapur. The data pertaining to length, breadth and the pairs of cirri were subjected to statistical analysis. The relationship between length and breadth shows allometric growth. The rate of increase in length in relation to breadth is not statistically significant up to the 10 P.C. stage. Increase in length is faster up to 12 P.C. stage.
