welcome back :)

Did you want your golden barbs back? there's two of the descendants left...

also, toying with the idea of a post about Bothriolepis - anything I should know? and what advantage is there in spawning at sea?

Glad to see the fish still live! Had to leave all my friends (including the python and Saratoga) back in Melbourne. Alas, will not be in Perth (or this hemisphere for that matter) for much longer - will hopefully have a 2 yr position in Beijing at the end of the year ( ... )

Hmm, the osmotic benefit didn't occur to me - good point! the converse - spawning up-river - certainly would have made sense back when there was nothing in land to eat you, but non-euryhaline fingerlings certainly would prefer the ocean even with m,ore chance of a toothy death, wouldn't they?

Also it should be noted that there are at 12-15+ spp. of Bothrio in the freshwater (fluvial-lacustrine) Mid-Devonian (Givetian) Aztec Siltstone of Antarctica - seem to have produced a rift-lake cichlid-esque species flock - and suggests that (like cichlids) they lacked a dispersive larval stage (limited dispersal of juvies leading isolation and speciation within a single freshwater system).

All my refs are currently in transit from Melbourne... will give you citations when they arrive.

Glad that you enjoyed your time - and achieved so much - in the Barony of Stormhold!

Welcome back.

How long before you leave our shores?

Probably Dec-Jan at this rate.
