Return to sea?
[edit]This article appears to contradict Sesarmidae, which states "They do not need to return to the sea even for breeding." mgiganteus1 (talk) 15:55, 5 March 2012 (UTC)
- Indeed. This article says in the section Terrestriality and migration:
- There is no clear distinction between "terrestrial" and "semi-terrestrial" crabs, nor between "semi-terrestrial" and "aquatic" crabs.[2] Rather, there is a continuum of terrestriality displayed among the true crabs, although even the most land-adapted crabs must still return to the sea to release their eggs.[3] Thus, although terrestrial crabs can be found many kilometres from the sea, they have to complete annual migrations to the sea.[3]
- Yet this article also says, in the section Ecology:
- Terrestrial crabs have often evolved from freshwater crabs, since the physiological changes needed for living in fresh water are pre-adaptations for terrestrial living.[5]
- I presume that the passage must still return to the sea should simply be must still return to water, but I'm no expert on this so I'm not going to venture to make the change. I'll put a dubious tag on it though. Duoduoduo (talk) 15:25, 18 October 2012 (UTC)
size matters!
[edit]Someone please add metrics about these little(?) beasts. You can't tell from the pic.
I bet they're yummy with butter! 67.162.165.126 (talk) 01:01, 29 June 2013 (UTC)
