Nudibranch in Lembeh
This week’s featured nudibranch is the Ceratosoma gracillimum since we’ve seen so many different species of Ceratosoma this week! It’s been an awesome week for nudibranch in Lembeh and we can barely keep track of all the species we’ve seen. Ceratosoma nudibranchs tend to be quite large and so easier to spot (and photograph!) and they have a very distinctive ‘T-bar’ shape.
Many people will point at any colourful slug in the water and call it a nudibranch. However, while all nudibranchs are sea slugs, not all sea slugs are nudibranchs! The name comes from Latin ‘nudi’ meaning ‘naked’ and ‘branch’ referring to the lungs. Nudibranchs, therefore, all have external lungs. These can be easily seen on most species as the branchial plume protrudes from the back of the body. It is thought that the Ceratosoma nudis have evolved the extra lobe that curls up at the rear of the body as a distraction and protection for the delicately exposed lungs. When you see as many nudibranch in Lembeh as we do, it’s easy to become a nudibranch nerd!
It’s been a fun week here at Two Fish Divers Lembeh Resort as we welcomed Conny from Germany to start her PADI Divemaster internship here. After an intense 10 days of training with instructor Dan, Conny has now completed her PADI Rescue Diver Course and 5 PADI specialty courses meaning she has now achieved the rating of Master Scuba Diver. This training will serve her in good stead as she continues on to Two Fish Bunaken to start her professional training proper.
With amazing critters, Lembeh is a great location to tick off during your PADI Divemaster Internship. It’s also a great place to continue your dive education. This week we have taught the PADI Peak Performance Buoyancy, Underwater Naturalist, Night, Deep and Nitrox specialty courses! Interested in diving and spotting nudibranch in Lembeh?
