Elysia ornata from American Samoa

July 21, 2001
From: Don Barclay


Hi Bill,

Here are a couple of pics of the "typical" Elysia ornata from American Samoa, as promised. The rhinophores are considerably different, at least in color, from the very dark ones. The dark Elysia will average a bit larger than the typical E. ornata, also.

This one was collected at 1800 local time on 13 July 2001, on an algae-covered coral head in about half a meter of water (low tide), middle of Coconut Point, Nu'uuli, American Samoa. 27mm long.

Larry Madrigal says there are several areas on the island where both the dark Elysia and normal E. ornata are found together, but they appear to be one form or the other without intergrades.

Cheers,
Don

Thanks Don,
This is certainly what I would call 'typical' Elysia ornata. I will be ineterested to hear Kathe Jensen's opinion on the dark ones.
Best wishes,
Bill Rudman
