  1. Hi Lasse, Sorry for the lack of response. Since the beginning of this month, we have had 2 members of our family pass away. As a result, emails, orders, business, and life in general has been put on hold until now. I will email you shortly regarding the addition to your original order. Sorry for the inconvenience. Keri
  2. Here are two photos of a touch-me-not sponge. Here are two more photos of the shrimp. I took the first one in Dominica inside the sponge, Ray Haberman took the second in St. Vincent on the outside surface of the sponge. It is rarely out of the sponge. Les Wilk
  3. When Cindy and Everett brought this shrimp to my attention a couple of years ago, they noted that they were finding it only in touch-me-not sponges (Neofibularia notitangere). Since then I've made a point of looking inside touch-me-nots whenever I've gone diving in the Caribbean, and I have asked many others to do the same. I'm finding the shrimp inside about 25% of the sponges I check, and from the reports I've been receiving it's pretty clear that it has a very broad distribution in the tropical West Atlantic --- wherever you find the touch-me-not sponge. The main reason this shrimp is so "unknown" is that its body color perfectly matches that of its host environment, i.e. the inside of the sponge's excurrent opening, and its white claws (not mentioned in the original 1949 description, and unusually subdued in Tepper's photo) blend in perfectly with the white worms that live inside the sponge. When the worms are out you'll have a hard time seeing the shrimp. Another reason is that divers are told to keep away from touch-me-not sponges, which is not a bad suggestion. This is a great example of how underwater photographers can contribute to the advancement of science. The colors of preserved specimens can differ greatly from life colors, for two reasons: the specimens are dead, and they have been immersed in preservative. Both can cause dramatic color changes. Underwater photographers can supply not only the missing color information, but also accurate information about habitat, behavior, and geographical distribution. Thanks to Cindy and Everett and their friends, Periclimenes harringtoni has been "resurrected" after 60 years of obscurity, and now has a common name --- the "whitefoot shrimp". Look for it. Les Wilk
  4. For the worm lovers out there (Leslie?). Found at 60 feet off Dominica last July. What are they and what are they doing? Les
  5. John McCosker is a world expert on snake eels. I think he would agree that based on the photos alone one cannot distinguish whether it's E. intertinctus (spotted spoon-nose eel) or E. punctifer (snapper eel). However, E. intertinctus has never been reported from the eastern Atlantic, while E. punctifer has been reported from Sierra Leone and south to the Democratic Republic of Congo. Based on location, there is a high probability that this is E. punctifer. This sighting would be a significant range extension for E. punctifer. In our DVD field guide we indicate how to unambiguously separate the two species: "The feature used by ichthyologists to most reliably distinguish this species from E. intertinctus is the nature of its preopercular pores. These are small openings on the lower side of the head, slightly behind the mouth and in front of the opercle. E. intertinctus has 2 rather inconspicuous pores, while E. punctifer has three pores, each one usually surrounded by dark pigment." Unfortunately, those pores are not visible in the photos. Les Wilk
  6. I agree with Luiz on all of them except the third one, which looks more like a wrasse blenny (Hemiemblemaria simula ) Les
  7. A nice (rare) find! That's Leptopisa setirostris in the family Mithracidae. In our upcoming marine creatures guide we are calling it the "roughnose decorator crab". Note the hairs (setae) on the rostrum. Les www.reefnet.ca
  8. Nice!!! See you in a month. Les
  9. In the article mentioned by Bill, http://scubageek.com/articles/wwwdome.html , the first paragraph states: "The main drawback of a flat port on an underwater camera housing is the narrowed field of view caused by refraction at the planar air/water interface. The object seems closer, so that less of it is seen by the camera lens. In fact, the theoretical maximum angle of view behind a flat port is 97.2 degrees. A spherical dome port removes this problem" THAT is why you use a dome port for underwater wide angle photography --- it restores the capture angle of your lens. Improved corner sharpness, etc. are just icing on the cake. Les Wilk
  10. In the ReefNet DVD under "hybrid hamlet" we have included a photo (11 of 12) from San Andres that is almost identical to yours. We also have a photo of a masked hamlet without a mask. For hamlets, it's extremely hard, and very subjective, to define a dividing line between a "species" and a hybrid. Les Wilk
  11. This is one form of Halicampus crinitus (banded pipefish). Les
  12. Autopsea - You paid $350 for a SubSee and a port adapter. Today, that same system would cost roughly $450-500. The 150 euros that you saw is for ONLY the SubSee. You actually saved over $100 by ordering so far back londonsean69 - Mid-march should not be a problem at all. If everything goes smoothly, we should have all backorders cleared out and have plenty of stock by the end of January. Contact us directly (info@reefnet.ca) so that we have an email record of your potential request, and we will add you to our backorder list. Keri
  13. After more than a year of struggling with poor-quality assembly facilities located all over the world, we've finally found a facility capable of consistently providing us the volume of perfect SubSee units that we require. Over the coming weeks, they will be producing/assembling hundreds of units, so our very lengthy backorder list should be fulfilled by mid/late January. We are shipping SubSee units out in chronological order as they arrive. As for your initial question, Aqua_soul, the "average waiting time" is both difficult to estimate, and somewhat irrelevant at this point, since we are no longer searching for or fighting with sub-standard assembly facilities... full-scale production is now underway. We appreciate the extraordinary patience and commitment that our customers have shown us through our frustrating production difficulties.
