Lacy scorpionfish

Lacy scorpionfish, Rhinopias aphanes holds top position on the bucket list of many underwater photographers. You can not find this fish visiting regular diving destinations like Anilao or Lembeh, you’d add some adventure (and money) and visit Papua New Guinea, Australia or New Caledonia.

Usually they are found on offshore reefs, not deep, sitting motionlessly in ambush near crinoid, perfectly matching with surrounds. You are lucky if you managed to get a small collection of differently coloured Lacy – Golden, Grey, Greenish, Red.

Harpa harpa – beautiful predator snail

Harpa harpa

The family Harpidae comprises elegant marine gastropods with shell, resembling the strings of a harp. They are nocturnal hunters, hiding in the sand during the day and feeding on crabs and shrimps at night. The prey is enveloped by the foot and mucus, then saliva containing digestive enzymes is injected. Finally, partly digested crab is sucked out by the mollusc.

Amazing mimicry: Pseudoceros imitatus

Pseudoceros imitatus (Mimic Flatworm), one of my favourite flatworms, mimic Phyllidiella pustulosa (Pimpled Phyllidiella), very common toxic nudibranch. Phyllidiella can emit very toxic substances on the skin, extracting them from the sponges it feeds on. Our flatworm unfairly enjoys poisonous fame, avoided by predators!

Can you tell flatworm from nudibranch on this photo?

Do you see the difference?
