简单描述
检索表 | 型态特徵 | 形态测量图
Pectoral and caudal fins absent. Anal opening below front end of the dorsal fin. With 17-19 body rings. The snout is short and bent upwards (Ref. 35388).
胸鳍与尾鳍鳍不存在。 在背鳍的前端之下的肛门孔。 藉由 17-19个体环。 吻部是短而且向上弯曲.(参考文献 35388)
Intertidal to about 30 m (Ref. 6733), among rocks or holdfasts and lower branches of algae (Ref. 4509). Spawn in the summer months. Become sexually mature at an age of 2 years. Feed on small crustaceans and fish fry (Ref. 35388). Larvae are attached to the ventral surface of the males (Ref. 42359). Ovoviviparous (Ref. 205). Parental care is exclusively paternal (Ref. 42359). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
潮间带到大约 30 公尺 (参考文献 6733), 在岩石或钩子与藻类的矮支之中.(参考文献 4509) 产卵于夏天数个月中。 在一个 2 年的年龄时性成熟了。 捕食小型甲壳动物与鱼苗。 (参考文献 35388) 仔鱼被依附于雄性的腹面。 (参考文献 42359) 卵胎生的.(参考文献 205) 亲代养育是仅由雄性负责。 (参考文献 42359) 雄鱼带卵在一个孵卵袋是在尾部下面发现.(参考文献 205)
Males brood their offspring attached to their flattened ventral surface. All throughout the gestation period, parental care is strictly paternal. No further care is needed once the newborn juveniles become free-swimming (Ref. 42359).
Sex roles are reversed in this species. The females are the courting sex and change color more intensely than the males (Ref. 42363). Unlike in other pipefishes, the courtship ritual takes place in close contact with the substratum which may characterise adaptation to typical intertidal conditions (Ref. 42363).東大西洋: 挪威南部， Kattegat 與不列顛群島到西撒哈拉的里奧德奧羅。
