I measc na speiceas suntasach laistigh den ollfhine tá:

* ''Macrocheira kaempferi'' an portán faoilinne Seapánach, an speiceas portán beo is mó, atá le fáil ar bhun an Aigéin Chiúin.
* ''Libinia emarginata'', an portán crúbach rinneangaithe, speiceas a fhaightear i ngnáthóga inbhir ar chósta thoir Mheiriceá Thuaidh.
* Hyas, géineas crúbach, lena n-áirítear crúbach an lín chruinneogaigh (''Hyas araneus''), atá le fáil san Atlantach agus sa Mhuir Thuaidh.
* ''Maja squinado'', ar a dtugtar “an portán faoilinne spíonach" sa Ghaeilge, a fhaightear amach ón Tasmáin aus tá sé amuigh go mbíonn siad carntha suas ar a chéile, na portáin atá ag gluaiseacht níos gasta ag dul suas thar na cinn níos lú agus níos moille.<ref>Life.
