In coastal waters, tidal flows may also be strong and highly variable over scales of a few hours. While general features of currents are often well known, the variability of flow within currents is often much harder to assess.

Most eggs are small, and synchronized spawning results in the discharge of both types of gametes into the sea for external fertilization. Hermaphrodites usually bring in sperm from another individual through the incurrent siphon.
