Primitive jawless aquatic vertebrate: lampreys; hagfishes.

原始的无颚脊椎动物；七鳃鳗；八目鳗类鱼。

Extant jawless vertebrates, represented by lampreys and hagfishes, have innate immune receptors with variable domains structurally resembling T/B-cell receptors. However, they lack cardinal elements of adaptive immunity shared by all jawed vertebrates: T/B-cell receptors and major histocompatibility complex molecules.

在以七鳃鳗和盲鳗为代表的无颌类脊椎动物中，虽然发现了与有颌类脊椎动物T细胞受体(T-cell receptors， TLRs)、B细胞受体(B-cell receptors， BCRs)可变区具有相似结构的先天性免疫受体，却从未发现有颌类脊椎动物适应性免疫系统的核心组分：TCRs、BCRs、组织相容性复合体(Major histocompatibility complex， MHC)。

Very possibly the same will happen with this book, and it isn't just the colugos and tree shrews. The position of tarsiers (Rendezvous 7), and the grouping of lampreys with hagfishes (Rendezvous 22) are unsure. The affinities of the afrotheres (Rendezvous 13) and the coelacanths (Rendezvous 19) are still slightly unsure. The ordering of our rendezvous with cnidarians and ctenophores (Rendezvous 28 and 29) could be the wrong way round.

很可能本书也会同病相怜，这不仅仅是因为猫猴和树鼩——跗猴的位置（见第7纪），以及七鳃鳗和八目鳗类鱼的分组（见第22纪）尚不能确定；远古非洲哺乳动物（见第13纪）和腔棘鱼类（见第19纪）的亲缘关系也有待商榷；而我们在刺丝胞动物和栉水母类（见第28纪和第29纪）章节的编排上也许也是一个错误。

They are similar to those found in rivers; but as there are no suckers nor lampreys here, I know not by what fish they could be made.

它们和河流中可以看见的很相似。但这里没有胭脂鱼或八目鳗，我不知道它是哪一些鱼建筑起来的。

Today, only sharks and a few other marine species, such as sturgeons and lampreys, can sense electricity.

现在，只剩下鲨鱼和其它一些海洋生物，如鲟鱼和七鳃鳗等还仍旧保留着这种&超能力&。

And be sure the lampreys are not overcooked.

还有确保鳗鱼不要烧过了

To super-abundance once the larger carnivorous fishes were destroyed by sea lampreys.

超丰度一次较大的食肉鱼类被摧毁海上 lampreys 。

Not all adaptive immune systems use the immunoglobulin fold as the basis for specific recognition molecules: sea lampreys, for example, have evolved an adaptive immune system that is based on leucine-rich repeat proteins.

并不是所有的获得性免疫系统都是利用免疫球蛋白来特异的识别外来分子，例如七鳃鳗，它利用的是一种富亮氨酸的蛋白。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
