midshipman fishとは 意味・読み方・使い方

The midshipman fishes are the genus Porichthys of toadfishes. They are distinguished by having photophores (which they use to attract prey and after which they are named, reminding some of a naval uniform's buttons) and four lateral lines. Typical midshipman fishes, such as the Plainfin Midshipman, are nocturnal and bury themselves in sand or mud of the intertidal zone during the day. At night they float just above the seabed. Some species are armed with venomous dorsal spines and are capable of inflicting serious injuries if handled.
