Bubble Vision's video: Mucky Secrets - Part 18 - Sea Slugs inc Nudibranchs - Lembeh Strait

Sea slugs including nudibranchs. Part 18 of my documentary, "Mucky Secrets", about the fascinating marine creatures of the Lembeh Strait in Indonesia. Watch the full 90-minute documentary at http://www.youtube.com/watch?v=nJMZ6reOB0E A huge and fascinating diversity of sea slugs, or opisthobranchs (Opisthobranchia), are found in the Lembeh Strait. Opisthobranch means "gills behind", because their gills are located behind their heart. Most sea slugs have all but lost their protective shell, but compensate with more advanced weapons of defence. Over six thousand different species of sea slug are nudibranchs (Nudibranchia). The name means "naked gills", referring to the rosette of branchial plumes on their back, surrounding their anus. These gills vary greatly in form, but all have a large surface area for oxygen exchange. There are English captions showing either the full narration or the common and scientific names of the marine life, along with the dive site names. The full Mucky Secrets nature documentary features a huge diversity of weird and wonderful marine animals including frogfish, nudibranchs, scorpionfish, crabs, shrimps, moray eels, seahorses, octopus, cuttlefish etc..
