Egg-laying fish
Most fish lay eggs that hatch outside the body, either scattered in the water or laid on plants, rocks or nests.
Also: oviparous, egg scatterers
Most fish are oviparous: they lay eggs. Pelagic spawners such as cod, tuna and Indian major carps release tiny floating eggs in vast numbers and give no care. Others lay fewer, larger eggs on a surface and guard them. Some sharks, rays and skates lay large eggs in tough cases, which take months to hatch. Egg size and number trade off: millions of small eggs, of which nearly all die, or a few large ones with a better chance each.
