I don't know anything about fish spawning in clams but there is an interesting case of fish spawning in the gill chamber of certaiin lithodid crabs. Female liparid fish, Careproctus spp., use their long ovipositor to lay large diameter eggs in the gill chambers of king crab, Paralithodes camschatica, North Pacific, the box crab, Lopholithodes foraminutus, off California and B.C., stone crab, Lithodes tropicalis, off Namibia, and Paralomis granulosa, off Chile. Strangely, the eggs are laid in only one gill chamber at a time. Some references are: Hunter (1969) Pac. Sci. 23: 546-547 Peden & Corbet (1973) Can. J. Zool. 51: 555-556 Melville-Smith & Louw (1987) Sth. Sfr. J. Zool. 22: 140-142 Colin McLay. > Dear Fish-folks, > > A colleague of mine asked me to post the following message.
