Тезаурус:
- The experience of travelling in the huge amphibian, and the take-offs and landings on water increased my interest in aviation, but not enough to effect any change in my plans.
- The polarizing region thus has properties similar to that of the amphibian organizer.
- So, if groups of cells are removed from the early amphibian embryo, separated into individual cells, and then reaggregated, the cells mill about and sort themselves out so that, for example, cells that are normally on the outside of the embryo, such as the future skin cells, surround those that are normally on the inside, like future muscle cells.
- Reconstruction of a Carboniferous coal swamp, showing large lycopod and cordaite trees, an amphibian, giant dragonfly and millipede
- Frogs have their origins in the Triassic (they are a relatively recent amphibian innovation, and highly specialized).
- This amphibian is not totally aquatic, as some fishkeepers have been led to believe and it requires a large, dry area on which it can climb to feed and preferably burrow.
- There is only one notable exception to this amphibian rule and that is the extraordinary sharp-ribbed newt.

- If we were asking this question of an amphibian or reptile, which lays its eggs and goes away to live solitarily except when the mating season comes around again, we would answer it purely in terms of the physical ecology of the species.
- In the fertilized amphibian eggs, the upper animal region is heavily pigmented whereas the lower, vegetal, half is white and heavy with yolk.
- One case where the inductive signals may have been identified is in early amphibian development.
- By the late Carboniferous a vertebrate amphibian with weak stumpy legs had arrived, probably descended from the ichthyostegids.
- Fortunately most pet cats, if they do encounter a toad, quickly learn that it tastes bad and, after one preliminary nip, rapidly drop the squirming amphibian and never make the same mistake again.
