Description:
We show that reproductively mature male sea lampreys release a bile acid that acts as a potent sex pheromone, inducing preference and searching behavior in ovulated female lampreys. The secreted bile acid 7alpha,12alpha,24-trihydroxy-5alpha-cholan-3-one 24-sulfate was released in much higher amounts relative to known vertebrate steroid pheromones and may be secreted through the gills. Hence, the male of this fish species signals both its reproductive status and location to females by secreting a pheromone that can act over long distances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Weiming -- Scott, Alexander P -- Siefkes, Michael J -- Yan, Honggao -- Liu, Qin -- Yun, Sang-Seon -- Gage, Douglas A -- New York, N.Y. -- Science. 2002 Apr 5;296(5565):138-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Fisheries and Wildlife, Michigan State University, East Lansing, MI 48824, USA.
