"caecilian" 的定义和意义

What is a "caecilian"?

Caecilian is a limbless amphibian belonging to the order Gymnophiona. They are often mistaken for snakes or worms due to their elongated and cylindrical bodies. Unlike snakes, caecilians have distinct eyes and lack scales, possessing instead smooth, slimy skin. These fascinating creatures are primarily found in tropical regions, particularly in moist soils and freshwater habitats. Caecilians are highly adapted for burrowing, with specialized sensory tentacles on their heads to help them navigate and locate prey underground. They are known for their unique reproductive strategy, with some species giving birth to live young and others laying eggs. Despite their seemingly elusive nature, caecilians play a significant role in their ecosystems by controlling invertebrate populations and serving as prey for other animals.
