Cool facts about the Nudibranch

Being part of the rich Coral Triangle is what makes the Philippines an excellent, world-class diving destination. Philippines is famous for its never ending variety of the little beautiful nudibranch. Working for Quo Vadis Dive Resort we see these wonders of the ocean every day.

Did you know…

  • Nudibranchs, once like snails lost their shells over countless years of evolution. Today you can find many different chemical defenses among them; some can store cells within their body capable of stinging. Others can secrete acid which they release when danger presents itself. Though there is currently only one known species of nudibranch that can be harmful to humans as it eats the infamous “Portuguese man-of-war” jellyfish.

  • Nudibranchs are commonly referred to as sea slugs. Although this is true, not all sea slugs are nudibranchs.
  • Nudibranchs obtain their stunning colors as a result of the colorful food they eat. Due to each species being extremely picky eaters they will generally only consume one type of food leading to a plethora of color variations over the 3000+ species.
  • Some nudibranchs such as the “blue dragon” are capable of creating their own food through photosynthesis.
  • Following the Darwinian principle of natural selection or “survival of the fittest” some nudibranchs are known to be cannibalistic, generally eating the smaller of its species.

  • Generally they have very short life spans. Some may live up to a year, other merely a few weeks.
  • Nudibranchs are hermaphrodites meaning they are both male and female simultaneously, possessing sexual organs of each gender.

NUDI2

Nudibranch the tiny wonder snail

The word “Nudibranch” is derived from the Latin “nudus” meaning naked and “branchial” meaning gills. The gills are located in the centre of the back of a nudibranch, looking like a very pretty flower. In the front of body you can find two club shaped rhinophores that detect odours.

Nudibranchs are favourites among many divers due to their sheer variety of shapes and colours. As well, anyone can spot an enormous school of sardines yet a keen eye is required to spot these tiny creatures, thus creating a welcome challenge to the avid diver!

Where are they found?

There are well over 3,000 species of nudibranchs which can generally be found in the shallows, however, some species have be known to be found at impressive depths of 2,500m.

They can be found in tropical waters and freezing waters alike, such as in the Antarctic. Though why freeze when you can find them in the warm waters here in the Philippines, which is one of the countries with the most diversity of the nudibranchs in the world? If merely reading about them is not enough then you should book your next holiday with Quo Vadis Dive Resort and we will make your dreams happen!
