Alertichthys blacki is a little knownmarine fish species from the order of the perch-like (Perciformes)foundin New Zealand . The species has so far been proven at a depth of 458 to 549 m.
features
Alertichthys blacki becomes 15 to 20 cm long and has a laterally flattened body that is covered with relatively small scales. The dorsal fin is divided into two by a deep incision. It is supported by seven strong fin spines and 17 soft rays. The anal fin has two spines and nine soft rays, the pelvic fins one thorn and five soft rays. The pectoral fins are located relatively far down and, similar to the closely related Zanclorhynchus spinifer , can probably be used together with the pelvic fins for a gait-like, quadruple locomotion on the ground, a locomotion that is very unusual for fish.
Systematics
Alertichthys blacki is assigned to the pig fish (Congiopodidae) in most sources . In Ishii and Imamura, the species forms together with Zanclorhynchus spinifer and, in contrast to the genus Congiopodus (subfamily Congiopodinae), the subfamily Zanclorhynchinae. Mandrytsa (2001) and Betancur-R. (2013 and 2017) raise the Zanclorhynchinae to the rank of an independent family, the Zanclorhynchidae.
