Crocodiles, alligators, caimans, and gharials the Crocodylia, known collectively as crocodylians (or crocodilians) are the world s largest living reptiles. The largest of them, probably the estuarine or saltwater crocodile, Crocodylus porosus, can grow to almost twenty feet and weigh more than two thousand pounds.

They are formidably strong, active predators, with jaws that can tear apart large prey items, yet a mother or a father can gently...

This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management.
A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene...
