|The family Aglajidae
includes elongate species with small internal shells. Most are
nocturnal but brightly colored species such as Chelidonura hirundinina are
diurnal. They are predators feeding on flatworms, polychaete worms or
other opisthobranchs. At least 15 species are known from Hawaii in five
genera (Aglaja, Chelidonura, Migaya, Navanax, Odontoglaja and Philinopsis).
