Talking of marauding predators, I watched this cuttlefish cautiously from the safety of my crevice home. It grabbed a small fish with its long tentacles and I wondered who had been the unlucky victim. Before the cuttlefish jetted away, I saw a sea scorpion’s tail sticking out from its tentacles. That fish’s camouflage hadn’t deceived the superb vision of the cuttlefish this time, with fatal consequences! Sad to see I guess, but cuttlefish have to eat and better a sea scorpion than a tompot blenny, especially as sea scorpions can eat young tompot blennies too.
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!
Close escape today! I was on the ‘balcony’ (all right then, the rock ledge) outside my home, nosing around when whoosh down came a diving bird, a shag. It almost caught me in its sharp beak! I flicked speedily into the back of my crevice and stayed hidden there as the shag continued to swim around my rock, prodding its beak into many of the cracks and crevices looking for food. I saw an unfortunate corkwing wrasse (a type of fish) being crunched. I am now a bit nervous about coming out again. It’s a good thing I spotted this predator so quickly. Having my eyes set so high on my head is a brilliant adaptation that helps me see well in all directions.
