1 In most cases, egg sizes are the largest observed in histological sections and may not be representative of the actual sizes of eggs spawned.
2 Periodicities are listed as either S, seasonal and synchronous; A, aseasonal, continuous, and asynchronous; and/or F, continuous breeding
with fluctuating levels of gamete production.
