Crocodile and bird - Habit in biological copulation

The crocodile species has the same faithful characteristics as its mate, which is the information concluded in a recent study in Molecular Ecology. This study was carried out for 10 years by a team of scientists from the Savannah River Ecology Laboratory that has revealed that up to 70% of alligators are attached to their partners for many years.

A research team, led by Dr. Travis Glenn, Ruth Elsey, Tracey Tuberville and Stacey Lance, spent a decade experimenting with crocodile behavioral traits in the wildlife world of Louisiana Rockefeller Wildlife Refuge ( RWR). When they choose a potential child, they monitor its behavior in different seasons, then observe whether it interacts with a mate or intercourse?

Mr. Lance said: 'In the environment of the number of crocodiles as large and dense as the RWR, we do not expect them to find exactly what you are dealing with. But surprisingly, up to 70% of the children we follow find exactly their sexuality. I did not expect that there were crocodile couples coping with each other since 1997 and still continued until 2005 and they were probably building nests in this transition season. '

This new discovery has given people a better understanding of the very complex crocodile process. There is almost no concept of caring for parents in reptile animals, nor do any crocodiles show their care through raising and protecting the nest. In 2001, scientists discovered a multi-origin with a copulation system in crocodiles, however, it is still impossible to know how to benefit species.

Crocodile is the only reptile dinosaur, it is a group of ancient reptiles including dinosaurs and birds evolved into birds. Crocodiles with a unique phylogenetic location can provide more information about the intercourse system of both bird ancestors and many other dinosaurs.

'In this study, combining molecular techniques with professional studies, we can point out some findings that have never been known about species.' Mr. Lance concluded. 'Hopefully future research will bring even more interesting and surprising results.'
