A Graphorn
In Fantastic Beasts and Where to Find Them, Newt explains that he saved the wizarding world's last pair of Graphorns from extinction. Under his care, these horned, hump-backed beasts produce a new generation of baby Graphorns, giving hope for the future of this magical species.
'They’re the last breeding pair in existence. If I hadn't managed to rescue them, that could have been the end of Graphorns – forever.' – Newt Scamander
