Editing Hatchling (section)

==Fish==
Fish hatchlings generally do not receive parental care, similar to reptiles. Like reptiles, fish hatchlings can be affected by xenobiotic compounds. For example, exposure to xenoestrogens can feminize fish.<ref>{{cite journal|last1=Brouwer|first1=Marius|last2=Kuhl|first2=Adam J.|title=Antiestrogens Inhibit Xenoestrogen-Induced Brain Aromatase Activity but Do Not Prevent Xenoestrogen-Induced Feminization in Japanese Medaka (Oryzias Latipes)|journal=Environmental Health Perspectives|date=April 2006|volume=114|issue=4| doi = 10.1289/ehp.8211|pmid=16581536|pmc=1440771|pages=500–506}}</ref> As well, hatchlings raised in water with high levels of carbon dioxide demonstrate unusual behaviour, such as being attracted to the scent of predators. This change could be reversed by immersion into gabazine water, leading to the hypothesis that acidic waters affect hatchling brain chemistry.<ref>{{cite journal|last=Raloff|first=Janet|title=Acidification Alters Fish Behavior: Higher Carbon Dioxide in Oceans May Affect Brain Chemistry|journal=Science News|date=February 25, 2012|volume=181|issue=4|url=http://www.questiaschool.com/library/1G1-281900482/acidification-alters-fish-behavior-higher-carbon |url-access=subscription|doi=10.1002/scin.5591810412|pages=14}}</ref>
