lamprey

1 Again, Seneca tells us that Augustus ordered Pollio’s crystal smashed and all his lamprey pools filled.

2 The illustration shows the V-shaped Vertebrata clade, which includes lancelets, lampreys, fish, lizards, rabbits, and humans.

3 "Sea lampreys have provided an additional clue. Now we need to look even further back in evolutionary time to discover when the gene circuitry governing hindbrain formation first evolved."

4 Lamprey is a typical migratory fish, some time in the sea of life.

鳗是一个典型的洄游鱼类，一些在海上的生活时间。

5 King Henry I ate a lamprey, a parasitic fish that is known to bring harm to humans.

亨利一世国王吃了一条七鳃鲤，这是一种已知会对人有害的寄生鱼类。

6 The larger of the two new species, Yanliaomyzon occisor, stretched over two feet long, making it the biggest fossil lamprey yet uncovered, about the size of the largest living lampreys.

7 It involved a fish tank stocked with lampreys as well as an alteration to the terrace’s paving stones: A handful of tiles were removed to expose the soil underneath.

8 And the genes found active only in the joints of the skate and in other vertebrates were active throughout the lamprey’s body.

9 Which would you rather be: a lamprey or a desert island?

10 Moffatt had found lampreys at several new sites, well into the tropical zone above the Tropic of Capricorn.

11 Then came lamprey pie, honeyed ham, buttered carrots, white beans and bacon, and roast swan stuffed with mushrooms and oysters.

12 Beneath it scamper little lampreys and tadpole shrimp, two prehistoric life forms, which stopped evolving before humans arrived on the scene.

13 Here you learn, for example, that the lampreys and the tadpole shrimp are species believed not to have evolved in millions of years.

14 "We found that not only are the same genes but also the same cue is involved in sea lamprey hindbrain development, suggesting this process is ancestral to all vertebrates," said Bedois.

15 A couple of inches below is a mound of sand around which swim little brown eel-like lampreys and bright orange Triops cancriformis, or tadpole shrimp.

16 Like other vertebrate animals, sea lampreys have a backbone and skeleton, but they are noticeably missing a feature of their heads -- a jaw.

17 Dams transformed the free-flowing freshwater highways that once supported abundant salmon runs, lamprey and other life.

18 “The lamprey fossil record is very sparse and poor,” Miyashita says, with mostly small species, only a few inches long, known from the first two hundred million years of their history.

19 This, on the condition that it take steps to salvage and relocate fish and make a “sufficient effort” to ensure that no more than 30,000 juvenile lampreys were killed in the process.

20 In contrast, he says, lamprey cartilage is soft and flexible, as if their skeleton “is one big joint.”
