Weblatissimus is in somite counts. L. latissimus is a high-count form, with about 240-250 somites; L. pseudolatissimus is a low-count form, with about 115-125 somites. Most of this difference is in the number of tail somites. For example, Bertin (1938) re-ported the following counts: for seven lar-vae of L. latissimus, total somites about 240, Web22-somite stage but in the transplanted embryos, it commenced as early as the 18-somite stage.
