I’m “eggscited” and “eggsstatic” now I have a full raft of eggs to look after! That’s because this spring I’ve:
a) secured a territory – my crevice home
b) done my spring cleaning
c) done an “eggscellent” job of attracting the local females in to lay their eggs.
I did this by wafting inviting smells (pheromones) from the enlarged glands just under my belly. Back on 24th March, Belinda was the first female to respond to my smelly message, she came in and had a good look at my home, I gave her a show of my bravado by whizzing round at lightning speed. Once I’d calmed down, she then decided to lay some of her beautiful dark purple eggs with me, which I fertilised immediately. Since then I’ve had visits from Brenda, Barbara, Bertha and Becky too. Belinda has been back twice. I’m very particular where they lay their eggs so you will see in the video that I boss them around to make sure they lay their eggs just where I want them to! They tolerate a little gentle barging and fin nibbling as they know I have a good track record as a Dad; I’ve lived in this crevice for 3 years and have been very successful looking after eggs.
I noticed this year that the females visited us more established males in the better crevices first. Byron and I are the ‘top dogs’ on the reef and we both had a good layer of eggs in our crevices a week or two before the females started to lay eggs with Billy, a small younger male tompot blenny with an inferior crevice home.
I’m glad I chased that velvet swimming crab out when I did. I’ve been in dire need of my crevice home to myself for the last few days. Gales hit the south-west coast but there seems to be some debate whether it was just very windy or officially ‘Storm Doris’, as some of the newspapers called it. It felt like Storm Doris to me. Take a look at this video, imagine what it’s like around my reef, a bubbly wild underwater whirlpool! I’m staying hidden away in the narrowest, snuggest part of my crevice for now, using my fins to keep me safely in position.
The winds are now easing but there is still a big swell coming in from the open sea. The surfers are enjoying it!
Thank you for reading my blogs, I hope you’ve enjoyed them as much as I’ve loved writing them. There’s always so much happening on my reef to tell you about.
Take a look at this photograph, it shows me looking at the children’s book that is all about ME and my world under the sea. It uses lots of underwater photographs to tell you all about where I live, what I like to eat and what would like to eat me! My eccentric author was very keen that I should see the book so, when the first copies were printed, she brought one down with Paul (the photographer) to show me! I came out of my crevice home to have a good look, swam over it and ……
You’ve seen how my amazing my babies were swimming around in the plankton. The ones that managed to avoid being eaten and found enough plankton to eat have grown to around 2 cm long and have now settled back on the reef. The researchers are not sure how they find a good home reef. It may just be luck or something to do with them being able to recognise the smell of the area they hatched from. Some coral reef fish know which reef is home from the sound the waves make!
When my babies first settle they are quite colourless, but soon take on camouflage colours to help them match their surroundings. You can see that their head tentacles have started growing and their pectoral fins are just visible with some black pigment.
Thank you to the National Marine Aquarium Plymouth for their help in getting this photo. The NMA is an excellent place to see tompot blennies like Benny the Blenny and lots of other UK marine life.
Hey, this shows what my tompot blenny babies look like when they have left home, having hatched from those eggs that I’ve been guarding. Swimming among the plankton in the open sea, they are very sleek with gorgeous big eyes and are between 4 and 20 mm long.
When they first hatch they eat very small plant (phyto-) plankton and animal (zoo-) plankton, the youngsters grow quickly and are then able to eat larger plankton. Bigger fish larvae and jellyfish in the plankton are a real danger and my babies have to make smart evasive moves if they see they are about to be grabbed!

This photo was made possible by the National Marine Aquarium in Plymouth so many thanks to them. Paul, my underwater photographer, would never be able to spot and photograph one of my babies in the wild!
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!
