Cuthona divae with eggs [2]

July 25, 2007
From: Jackie Hildering

Both dives today allowed me to find Cuthona divae with eggs but different eggs at each site. On the NE Pearse site the animals were on hedge hog hydroids (Clavactinia milleri).

Locality: NE Pearse, +/-40 feet, British Columbia, Canada, Pacific Ocean, 28 April 2007, Wall. Length: 3 cm . Photographer: Jackie Hildering.

[See message #20138 for eggs at "Bob's Spot" site where the animals were on barnacle fur hydroids (Hydractinia ).]

Hi Jackie,

As I mentioned in my reply to message #20138, you have the eggs of two different species here. I am going to guess that one was feeding on the hedge hog hydroids (Clavactinia milleri), while the other was feeding on barnacle fur hydroids (Hydractinia). Cute common names

Bill has pointed out to me that the small animal just above the big one - can see it clearly in middle right photo, might not be Cuthona divae, but another species, possibly Cuthona cocoachroma or C. concinna. This would certainly explain the two different egg mass morphologies.

Hope this helps,
Dave Behrens
