"astomous"的意思是：无头的，无首的。
以下是一篇以"astomous"为关键词的英文范文：
The fish we caught today was astomous in size, with a large head and a long body. We cooked it over a campfire and enjoyed the delicious taste of fresh fish. However, we noticed that the fish had no head, which was a bit surprising because we usually associate fish with having heads. But it turns out that this fish species is naturally astomous, which means that it lacks a head and is able to survive without it. This is an interesting example of how adaptations can help animals survive in their environment.
astomous的中文意思是[鱼]无颚的；无鳃的^[1][2]^。
astomous一般指无腮类鱼，这类鱼是没有腮，利用皮膜的呼吸来代替鳃的呼吸。由于这个特点，它们和娃娃鱼一样，只能在水里呼吸，离开水就不能呼吸，会活活饿死^[1]^。
astomous的意思是[adj.]无头的；不分的；不可分的；杂乱无章的^[1][2]^。
例句：The river is astomous and turbid.这条河流不分你我了，而且水很混浊。
