And it’s sooo colorful that its most likely to be very, very poisonous! o_O Oh, yeah, this sea slug is called Nembrotha megalocera. It can be found at the Protector Reef in Red Sea, off Sudan at a depth of 8 meters. This species has close similarities in colour to a group of western Pacific species, including Nembrotha rutilans. It is reported to swim by lateral flexion when disturbed.
