Structural specialties, curiosities, and record‐breaking features of crustacean reproduction

摘要: Crustaceans are a morphologically, physiologically, and ecologically highly diverse animal group correspondingly their reproductive characteristics. They have evolved structural specialties with respect to penis construction, sperm form, storage, fertilization, brood care. Unique in the kingdom safety lines that safeguard hatching first molting. Further curiosities dwarf males parasitic sessile crustaceans bacteria-induced feminization gigantism of crustacean hosts. Record-breaking features relative length, size, clutch chromosome number, viability dormant eggs, fossil ages penis, sperm, brooded embryos. These examples from single invertebrate subphylum life history aspect illustrate morphological solutions functional requirements can be as spectacular behavioral adaptations. may provide valuable sources for comparative morphologists, ecologists, evolutionary biologists, applied biologists advance topical issues such competition, posthumous paternity, evolution care, adaptation freshwater, infectious feminization, sustainable male-based fishery, maintenance genetic diversity under conditions limited mating opportunity, long-term impact pollution on genotype phenotype.
