Zanclorhynchus spinifer
Zanclorhynchus spinifer
Zanclorhynchus spinifer is occurring in the Southern ( Antarctic ) Ocean Meeresfischart of the order Perciformes ( Perciformes ). The species was observed previously at the Prince Edward Islands, the Crozet Islands, Kerguelen at the, at Heard Island, Macquarie Island and the Kara -Dag - seamount northeast of the Prince Edward Islands.
Features
Zanclorhynchus spinifer is 40 cm long and has a laterally strongly flattened body whose height is 30 to 33% of standard length. The length of the large, flattened head is 33 to 35 % of the standard length. The eye diameter is from 22 to 33% of head length. The snout is pointed and longer than the eye diameter, the small mouth is terminal. Jaw and palate are covered with small teeth. There are strong spines on the nostrils and the back edge of the Knochengrates around the eyes. Another directly behind the eye on the Praeoperculare and the longest and strongest on the gill cover. The latter reaches about 25% of the head length. The top of the head and the " cheeks " are partially wrinkled. The dorsal fin is divided in two by a deep incision. It is supported 8-10 strong spines and 12 to 15 unbranched soft rays. The third and longest fin spines, the length of the head. The anal fin has 10 or 11 fin rays, the pectoral fins 9 unbranched fin rays and pelvic fins a sting and 5 segmented fin rays. The pectoral fins are sitting relatively far down and can, together with the ventral fins are used in a vein-like, quadrupedal locomotion on the ground, a way of locomotion, which is very unusual for fish. The base of the pectoral fins is narrow. The fin rays of the caudal fin are branched and segmented. The lateral line extends over 11 to 15 spiny and voided shed from the gill cover to the middle caudal peduncle. The body of the fish is covered with relatively small, prickly scales, which give it a slightly rough appearance. Some areas, such as on the dorsal fin base, are scaleless. Zanclorhynchus is spinifer brown, purple and ocher- colored and shows some dark markings. The fins are ocher with dark bands. Dark spots are located at the base of the second dorsal spine and the back portion of the first, hartstrahligen dorsal portion.
Way of life
Zanclorhynchus spinifer lives in depths of 5-340 meters between kelp and on sandy seabed and feeds on small invertebrates, especially amphipods.
System
Zanclorhynchus spinifer in most sources associated with the pig fish ( Congiopodidae ). In Ishii and Imamura type together with Alertichthys blacki and in contrast to the genus Congiopodus ( subfamily Congiopodinae ) the subfamily Zanclorhynchinae. Mandrytsa (2001) and Betancur -R. (2013 ) raise the Zanclorhynchinae the rank of a separate family, the Zanclorhynchidae.
