Pleurobranchaea

A monster came to our lab.


Pleurobranchaea californica.


Dr. Gillette said this is a super-Tritonia.
I gave it a piece of salt, but did not induce the escape swim.

Tank 080609

Tanks look great.
Slugs ate seapens well. No death reported over the weekend.

Tank D had no water in upper level, because the bypass valve was left open. The water condition was fine, though. I cleaned the upper level and adjusted the valve.

15 Tritonia in A, 15 Tritonia in B, ? Aplysia in C, and 5 Tritonia in E.

Tank 080606

There was the temperature alert from Tank D this morning.
I went down to check it and found that the bottom floor where motor and cooling units are sitting was all wet. There must be some water leak from somewhere.

Tank D often has this this leakage problem. I could not found detect where it is. No cracks, no loose connection.

Today, I found it.
This tube pass water from the upper tank to the lower tank.
The nozzle of this connection was loose. It was spraying water on the acrylic board.




I must have hit the cover when I opened or closed this cover for cleaning. I cleaned them all three times this week.
