However, in recent years both field and laboratory studies have provided evidence for an astonishing array of parental care in amphibians. We began our search of parental care traits by extracting all relevant data from the most comprehensive review of parental behaviour in squamate reptiles to … On the contrary many reptiles species have little parental care. Newly hatched baby. E.g. A majority of domesticated animals have the advantage of having a caretaker who can train them for different things that can improve their overall fitness. INTRODUCTION Parental care has been defined as "any kind of parental behavior that appears likely to increase the fitness of the parent's offspring" (CluttonBrock, 1991).

On the contrary many reptiles species have little parental care. It seems that you might have a lot to thank cockroach milk for your survival to adulthood. The Evolutionary Ecology of Parental Care in Lizards.

He conducted a literature search to see how often mentions of parental care in reptiles are recorded. ADVERTISEMENTS: In this article we will discuss about the parental care provided by amphibians. The evolution of parental care is beneficial if it facilitates offspring performance traits that are ultimately tied to offspring fitness. List five characteristics of living amphibians.
