Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  I hoki mai ia ki Mount Holyoke i te 1872, i whakaako i te pāngarau me te hitori taiao i mua i tana noho hei kaiwhakaako hākinakina o te whare wānanga mai i te 1876 ki te 1891. I haere tonu a Clapp i ana akoranga paetahi i te Louis Agassiz's Anderson School of Natural History i Penikese Island, Buzzard's Bay, MA i te 1874. I tangohia e ia te kupu a Agassiz "Akohia te taiao, kaua nga pukapuka!" a ka whakamahia ki tana ake whakaakoranga. I whakauruhia e ia tana matauranga i akohia ma te akoranga embryology i Mount Holyoke, i whakakapihia e nga tauira mai i nga akonga o tawahi. I te wā raumati o te tau 1875, i kohikohi a Clapp me ētahi atu o ngā kairangahau mō ngā pūngāwerewere o New England i ngā ngārara mai i ngā Maunga Ma o New Hampshire, i ngā kāwanatanga o waenganui o te Moana-a-Kiwa i te tau 1877. (Ko nga tuunga ko te teihana moana o te Whare Wananga o Johns Hopkins i Beaufort, SC me te Smithsonian Institution i Washington, DC) I whakaotihia e Clapp nga rangahau poto mo nga kikokiko heihei me nga rewharewha i te Massachusetts Institute of Technology i raro i te W.T. Sedgwick me te Williams College i nga tau moata o te 1880. I te timatanga o te tau 1888, i hono a Clapp ki te Marine Biological Laboratory i Woods Hole, MA, i reira ia i whakahaere rangahau taiwhanga, a, i muri mai ka noho hei kaiwhakaako me te kaitiaki. I whakaputaina tana tuhinga tohungatanga mo te toadfish i roto i te Journal of Morphology i te 1889.  Pātai: He aha te āhua i haere ai a Clapp ki te kohikohi i ngā pepeke i te tau 1875?
