Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

Strategic ejaculate adjustments occur when males modify their investment in sperm and
nonsperm components of the ejaculate according to the context. This strategy is expected to …

Observations of wild male O. maya suggest that temperatures below 27° C favour their
reproductive performance. From these observations we hypothesize that, as in females, the …

Spermatozoa released by males should remain viable until fertilization. Hence, sperm
longevity is governed by intrinsic and environmental factors in accordance with the male …

Loliginid squids provide a unique model system to explore male alternative reproductive
tactics (ARTs) and their linkage to size, behavioral decision making, and possibly age. Large …

Under intense sexual selection, males less successful in fighting and mate guarding often
adopt alternative reproductive tactics. In many species, males employing alternative tactics …

Animal species usually have a single sperm-storage site in the female body, but females of
the squid Heterololigo bleekeri possess two distinct sperm-storage sites simultaneously …

This book is perhaps the first attempt to comprehensively project the uniqueness of
molluscs, covering almost all aspects of reproduction and development from aplacophorans …

Emergence of male dimorphism within a species is the evolutionary process of disruptive
selection. In squids, two types of male mating behaviour, known as alternative reproductive …

Sperm competition is a powerful postcopulatory selective force influencing male adaptations
associated with increasing fertilization success, and it is usually related to the evolution of …
