The foregut of the Mysida (Crustacea, Peracarida) and its phylogenetic relevance
The foreguts of the mysids Antarctomysis maxima, A. ohlinii, Hansenomysis antarctica, Heteromysis formosa, Mesopodopsis slabberi, Neomysis integer, Paramysis kessleri, Praunus flexuosus, and Siriella jaltensis were examined by maceration methods, histological techniques, and scanning electron micros...
