A Dad’s duties

Tompot blenny, single with eggs 1

Here, I’m using my pectoral (shoulder) fins to fan water over Belinda’s developing eggs and keep them healthy. I also have a special gland near my tail that releases important stuff to keep bugs from growing on the eggs. Female tompot blennies like Belinda take care to lay their eggs in a single layer that makes it easy for me to give them all a good wipe over.

Since Belinda’s visit, two other female tompot blennies (let’s call them Barbara and Brenda) have been attracted by my smelly messages (pheromones) and have been flirting just outside my home at different times. I’ve encouraged them in and they have laid their eggs next to Belinda’s. I fertilised them straight away, as I need to make sure I’m their Dad. I have to be on my guard because lots of animals would love to eat my eggs. I can’t leave them unguarded for more than a few moments so I have to grab my own food very quickly!
