BLUE is for Boys and YELLOW is for Girls…..

Blue & Yellow Ribbon EelNo, we are not talking about this year’s fashionable wetsuit or fin colours – we are talking about Ribbon Eels!
How many times have you heard divers coming back from dives talking about the blue ribbon eel that they spotted or the small black ribbon eel that they were trying to entice out of its hole? What many people don’t understand is how these differing colours signify the different ages of ribbon eels – and yes, their gender too!
Unlike some marine species such as cuttlefish and leaf scorpionfish, ribbon eels do not change colour to blend in to their surroundings or because they are displaying mating or defensive behaviours, they change colour with age and as their gender CHANGES!

So, let’s take a look at the different stages that ribbon eels go through:
Ribbon eels begin life as juveniles which are easily recognized by the bright yellow dorsal fin which runs the length of their dark, black bodies. As the eel matures the black changes to a bright, electric blue with an equally vivid yellow dorsal fin; this marks the male stage of its life. The eel continues to grow and at approximately 1.3 meters / 4 feet its colour changes again, this time to yellow, and the eel enters its female stage where upon it is able to lay eggs.
Two Blue Ribbon Eels togetherRibbon eels are found predominantly on healthy coral reefs but they also seem to do well on damaged reefs too where they favour sand and rubble areas. They are frequently found hiding under rocks and ledges or buried in the sand with just their heads and upper body visible – it is quite a special sight to see the entire length of a ribbon eel at any stage of its life cycle. We have also noticed that the juvenile black phase eel is more regularly spotted on sandy and rubble patches whilst the electric blue male and yellow female are seen with more frequency at our dive sites that have a higher density of coral.
They all have long protruding nostrils which are almost sea horse like in appearance and are used to sense vibrations in the water. As with moray eels, divers often mistake ribbon eels as being aggressive as they are commonly seen with their mouths widely opening and closing in what could be interpreted as a threatening manner when they are in fact just breathing.
Despite their slender bodies ribbon eels have an incredible lifespan of up to 20 years and can grow to over one meter in length. Ribbon eels are carnivores and their diets consist of shrimps and small fish.
Ribbon Eel portraitRibbon eels do not appear to be seasonal and can be seen at all three of our resorts in North Sulawesi. Some of our best sites for seeing ribbon eels include Sahaung and Paradise Pier in Bangka; Circus and Tanjung Bulo in Manado; and Angels Window and Nudifalls in Lembeh – where they have been known to be spotted out swimming!
So now you know a little bit more about these amazing little eels maybe you’re feeling inspired to come and see some for real!
