Figure 3From: Variation in rates of early development in Haliotis asinina generate competent larvae of different agesVariation in rates of larval shell deposition between larvae of the same age (10 hpf) as revealed by in situ hybridisation against Has-Ubfm [GenBank: DW986191]. (A) An SEM image of a H. asinina trochophore reveals the position of the shell field (sf). (B - D) Representative variation in the spatial expression of Has-UbfmBack to article page
