许多变数：一条成年蚯蚓的长短取决于它是哪种蚯蚓 新浪科技讯 北京时间9月5日
消息，一名中国男子在自家后院发现一条半米长的蚯蚓，令邻居大为震惊。云南省宾川
县林业局职工李志伟(Li Zhiwei音译)请了几天假，准备把自家后院的积水排干，结果
发现了这条巨大的无脊椎动物。他说：“它看上去就像一条蛇。我很仔细地看了看，才
发现它实际上是条蚯蚓。”
他打算把这条蚯蚓养在自己家里。而生物学家打算研究这位“土壤居民”，以便确
定其分类以及弄清楚它在一个居民区长到这么长的原因。一条蚯蚓的大小和它所处的环
境有密切关系。如果它们吸收了适当营养，而且没有遭遇天敌，在潮湿季节往往会长得
更长。(孝文) |

但在电视节目上说过长的蚯蚓会很长很长。

Giant Gippsland earthworm
The giant Gippsland earthworm, Megascolides australis, is one of Australia's
1,000 native earthworm species. These Giant earthworms average 1 metre (3
feet) long and 2 cm (1 inch) in diameter and can reach 3 m in length.[1]
They have a dark purple head and a blue-grey body.
They live in the subsoil of blue, grey or red clay soils along stream banks
and some south or west facing hills of their remaining habitat which is in
Gippsland in Victoria, Australia.
These worms live in deep burrow systems and require water in their
environment to respire. These worms rarely leave their moist burrows. They
have relatively long life spans for invertebrates and can take 5 years to
reach maturity. They breed in the warmer months and produce large egg
cocoons which are laid in their burrows. When these worms hatch in 12 months
they are already 20 cm long.
Unlike most earthworms which deposit castings on the surface, they spend
almost all their time in burrows and deposit their castings there. Their
movements through the underground burrows can cause an audible gurgling or
sucking sound which allows them to be detected.[2]
Located near the town of Bass is the Giant Earthworm Museum. This building
allows tourists to crawl through a magnified replica of a worm burrow and a
simulated worm's stomach. Displays and educational material on the Giant
Gippsland earthworm and other natural history of Gippsland are featured. |
