Tracking larval fish across seasons reveals spawning hotspots around Korea
Seasonal surveys of ichthyoplankton across Korean waters reveal a striking contrast: 30 egg taxa and 61 larval taxa in February, versus 53 egg taxa and 154 larval taxa in July. This measurable increase in species richness underscores the importance of timing in marine surveys. Regional differentiation sharpened in summer, with *Engraulis japonicus* dominating both eggs and larvae. Understanding these spawning hotspots is foundational to ocean stewardship.

Fifteen krill species map the Benguela food web's nutritional architecture
Fifteen krill species map the Benguela food web's nutritional architecture, and the findings demand a recalibration of how we model these waters. Lantern shrimp are far more than a simple link between plankton and predators. Their species-specific diets, ranging from herbivory to exclusive carnivory, reveal a complex trophic tapestry. This empirical data, validated through stable isotope and fatty acid analysis, underscores the need for integrated food-web models.
