Letters

Diving in January

Where are good dive locations off Pacific in January?
Jennifer G. Smith, via Twitter - @JenniferGSmith

We recommended Palau in Micronesia or Hin Daeng and Hin Mouang in Thailand. Anyone any other suggestions? E-mail news@scubatravel.co.uk or tweet @SCUBANews.

Snorkelling in Cuba

We are a couple who love to snorkel so reefs need to be fairly shallow and close to a nice beach so we can enter from the beach. We have never been to Cuba before. Can you recommend a suitable area/place.

Can anyone help Susanne? E-mail news@scubatravel.co.uk and we'll pass your message on.


Creature of the Month: The Scarlet Lady Nudibranch

Coryphella browni, or the Scarlet Lady nudibranch, is one of the few animals to eat stinging hydroids, in particular the Oaten pipes hydroids (Tubularia indivisa). It not only doesn't mind their stinging cells, it actually puts them to use. The nudibranch passes the intact cells through its digestive tract and out to the cerata tips (the colourful projections on its body). Any animal taking a bite out of the cerata will discharge the stinging cells, then give up and go and eat something less painful.

Coryphella browni has a translucent body and numerous red cerata with white tips. The inner cerata are longer than the outer. It grows up to 5 cm long. You find it around the British Isles and Northern Europe. There are other species very similar to C. browni, such as Coryphella lineata which is distinguished by white lines down its body and along its cerrata.

Nudibranchs are hermaphrodites: possessing both male and female organs. If you see wavy white threads amongst the hydroid stems, these are the eggs of Coryphella browni.

Humpback whale
