127. Peacock Flounder (Bothus mancus) infested with Leeches


Subject: Infested with leeches. A Peacock Flounder’s (Bothus mancus) raised eye stumps and gill slits are plagued with leeches. Marine leeches are wormlike parasites that suck blood out of their victims with their suction cup-like mouth. In the process they inject the host with their saliva that contains an anaesthetic and anti-coagulant to keep the blood flowing painlessly.

Technique: Making a close-up shot of a fish is always a bit tricky... every species has its “flight distance”, the distance you can approach an animal without triggering an escape response. Always move slowly with your camera, avoid jerky movements and show that you’re not a threat, otherwise the fish may rapidly get away and ruin your clip.
