中国海毛颚类物种多样性的研究

A study on the species diversity of Chaetognaths in China seas

中国海已记录毛颚类有３７种，可分为３个生态类群，即暖水性、暖温性和深水类群。种数是由北往南、由近岸向外海递增。中国海毛颚类可划分暖温带区系、热带一暖温带混合区系和热带大洋区系。大多数种类广泛分布于印度洋、大西洋和太平洋等水域。

Thirty seven species of Chaetognaths which are divided into 3 ecological groups, i. e. warm-water (tropical and subtropical species), warm-temperate and bathybic group have been recorded in China seas. The number of species increases from north to south and from inshore to off shore. The Chaetognaths in China seas can be differentated into the fauna of warm temperate, mixed tropic-warm temperate and tropical oceanzones in geographical characteristics.
