. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. FUSION IN SOLITARY ASCIDIANS 199. FIGURE 4. Part of Figure 3 at higher magnification. The fibrous matrix is continuous between the fused animals allowing free interchange of the cells contained within the tunic. (Abbreviations: see Figure 2.) The majority of fusions were between individuals of equal size, but fusion between individuals of several-fold difference in size was also found. Frequency of fusion One panel was examined for frequency of fusion. Of 190 animals, 48 were single; occasionally they had unscored juveniles attached to their tunics. The re- maining 142 individuals were in direct physical contact with one or more conspe- cifics, yielding groups of 2-10 animals. As 29 individuals in these groups were unseparable by the method described above, a subsample of 13 of these was analysed histologically. These were fused. It was concluded that about 20% of those which occurred in groups were fused to conspecifics. Fusion was, with one exception, between two ascidians; one group of three fused individuals was found.
