Maybe one of these false clownfish is the dominate female in this anemone
Did you know that many of the lovely fish we regularly see on the coral reef have the ability to change their sex? The biological term is ‘sequential hermaphroditism,’ and wrasses, moray eels, gobies and clownfish are known to do this.
According to Wikipedia
“A school of clownfish is always built into a hierarchy with a female fish at the top. When she dies, the most dominant male changes sex and takes her place. In the wrasses (the family Labridae), sex change is from female to male, with the largest female of the harem changing into a male and taking over the harem upon the disappearance of the previous dominant male.”
The Spanish hogfish is one of the larger Caribbean wrasses
The blue-ribbon eel is one of the most beautiful
The fire goby is one of my favorites

I see divers and snorkelers slathering on sunscreen every time I go out on the Sea Rovers’ boats. Since there are only a limited number of dive sites at Menjangan and here in Pemuteran, it really worries me about the impact these chemicals may be having on the reefs. Here are some excerpts from an article from National Geographic and PADI. Click on the links if you want to read them in full.
The sunscreen that you dutifully slather on before a swim on the beach may be protecting your body—but a new study finds that the chemicals are also killing coral reefs worldwide.
Four commonly found sunscreen ingredients can awaken dormant viruses in the symbiotic algae called zooxanthellae that live inside reef-building coral species. Even low levels of sunscreen, at or below the typical amount used by swimmers, could activate the algae viruses and completely bleach coral in just four days, the results showed.
The researchers estimate that 4,000 to 6,000 metric tons of sunscreen wash off swimmers annually in oceans worldwide, and that up to 10 percent of coral reefs are threatened by sunscreen-induced bleaching.
So what’s a diver (or snorkeler) to do?
When it comes to sunscreen, any natural product (organic, biodegradeable etc) is better for the environment then the conventional one. Look for a brand that uses physical sunblocks such as titanium dioxide and zinc oxide instead of chemical ones.
Read the label. A product advertising itself as “reef safe” doesn’t necessarily mean what it says. Always look at ingredient lists to make sure reef-damaging substances (such as oxybenzone, butylparaben, octinoxate and 4-methylbenzylidine camphor, all of which have been shown to cause coral bleaching even at low levels) aren’t included.
Apply sunscreen at least 10-15 minutes before going in the water so that the lotion absorbs into your skin.
Now that you’re ready to make the switch to coral reef safe sunscreen (and human-safe), consider the 10 options below, all of which have a “1” rating from the EWG, and positive reviews from online consumers.

I wear a thin wetsuit or dive skin whenever I’m on the boat (I do have a noticeable tan line that starts at my wrists; I could wear my gloves if it becomes too unsightly). I try to sit in the shade, and if I can’t, I use a towel over my head to shield my face from the sun. A broad-brimmed hat would also protect your face.
Some of the world’s problems seem so big that there’s nothing we can do; consider making this small change to do your bit to protect our precious coral reefs.
Recent visit by the Green School out of the landlocked Port of Ubud, (http://www.greenschool.org) turned out to be a good opportunity to put the Nasty Nemo through her paces. And she handled it all with easy and space to spare.
The Green School was up on a field trip to the Biorock Project. Where they learn how to electrify coral to good effect 😉 After a morning of learning and snorkeling the projects they took a break to explore a local reef (Close Encounters) where they got to see first hand what can happen when local businesses work with the village and fishing community to help protect the local marine environment in a sustainable way.
The Next day they head out again this time to visit the Solar Powered Biorock offshore structures. The Biowreck and BioBoomer. The later named in honour of the once long time resident of the of the Turtle Project, run by my old mate Chris Brown just down the beach from us. Another longtime resident and local Eco warrior.
Then its prepare for the beach and Mucky Pirates Bay clean up.
DiveMaster Made and Captain Sahari lend a helping hand.
Despite the lousy visibility everyone heads out with a modicum of enthusiasm on their perilous mission to rid our bay of marauding plastic.
A Junior Eco Wench is Joined by Captain Botac scouring the Bay for hidden enemies amongst the fishing boats.
After a hard morning of snorkeling, diving and rescuing our beloved and now not so Mucky Pirates Bay. The lads and lasses of the Green School sit down to enjoy a well earned Nasi Bungkus.
