  • Cigar pteropod (Cuvierina columnella) | Palau, Blackwater Diving
    Wu Photo Naturalist ars gratia scientiae Home Journal Cigar Pteropod and Multi armed Mystery Cigar Pteropod and Multi armed Mystery Change of pace from whales a couple of small critters I encountered while blackwater diving in Palau last year The first is probably a swimming mollusc known as a cigar pteropod Cuvierina columnella which was around 1cm in size Thanks Leslie Probably a cigar pteropod Cuvierina columnella License image And the second well I don t know I think it s some sort of Cnidarian polyp but that s just a guess based on the general appearance of the gelatinous multi appendaged body with mouth in the middle once again something around 1cm in size Some sort of gelatinous thing Larva of tube anemone with lots of arms and a mouth in the middle If you happen to be a Cnidarian specialist and can ID this interesting little critter please let me know There are just so many fascinating forms of life in the ocean Update 10 Feb Looks like it s the larva of a tube anemone See this discussion from the Smithsonian National Museum of Natural History for more information ID and link via Allen Collins Thanks Allen

  • Unidentified Megalop Stage Crab | Blackwater Diving in Palau
    Cute Crustacean Conundrum While writing my previous post about spawning aggregations in Palau I rummaged through photos from my last visit to the island nation and found this Unidentifed crustacean that desperately wants to be a manga character Anyone know what this is These critters were relatively common during late night blackwater dives They re small like half the size of my pinky fingernail or smaller and they zip about in erratic patterns making full use of their multitude of multi jointed appendages Given their diminutive proportions and penchant for Brownian motion they are incredibly frustrating to photograph Front view of the critter s paws claws They come in a range of colours Besides this orange and magenta pattern I recall seeing deep purple as well as tan I wouldn t be surprised if there are more variations I m thinking these manga esque critters are larval crustaceans of some sort If you know what this animal is please clue me in Update via Jody Martin crab curator and Leslie Harris polychaete worm expert at Natural History Museum of Los Angeles Likely the megalop stage of crab development which is the final pelagic stage before settling down to change to

  • Spawning Aggregation Trip to Palau with Nauticam | April 2015
    tends to happen so quickly that the blink of an eye seems an eternity by comparison hence difficult to photograph I have photos of these fish spawning but none that I m entirely happy with so I m going back to try again That s what I do Pick a wall Beat my head against it Again and again Repeat Though I didn t get the Symphorichthys spilurus spawning shots that I wanted during my visit to Palau last year I did manage to get pictures of the developing fish embryo with the help of friends Tom Bowling who operates Biota Aquaculture Palau and Richard Barnden aka Numbnuts who is one half of the Unique Dive Expeditions team The long suffering other half is Paul Collins who is arguably as much a babysitter for Richard as he is a business partner Poor Paul Poor Palau actually For you fellow fish geeks here is a Symphorichthys spilurus embryo at 10 hours post fertilisation Fertilised Symphorichthys spilurus embryo at 10 hours License image And below is a wee baby Symphorichthys spilurus at 35 hours You can clearly see both eyes the spinal development yolk sac and anus Cute no Tom captured fertilised eggs while we were diving picture big scruffy Aussie dude with somewhat deranged expression charging madly into clouds of fish jizz while swooshing white net in the water quite the spectacle indeed and I took both of these photos using his field microscope with believe it or not a handheld D800 The photos turned out much better than I thought under the circumstances Symphorichthys spilurus fry at 35 hours License image The trip is nearly full thanks to the coordination and efforts of Phoebe at Nauticam There s just one spot left The plan is for six days of diving

  • Colorful Autumn Foliage in Kyoto 2014 | Momiji, Ginkgo
    globe unloading at every major tourist site To avoid getting entangled in a gaggle of gawking sightseers we sought out less frequented areas places not necessarily on the typical must do checklists and also endeavoured to avoid peak hours We set out each day on a quest for pockets of underappreciated beauty sometimes in remote places but often right in the middle of the action just steps away from where group tours squabbled for space Green momiji with pink momiji in background Kyoto License image My favorite leaves are those of the many varieties of Japanese maple trees known as momiji Literally translated the Japanese characters mean red leaf probably because the delicate leaves have a tendency to turn various shades of deep red in the autumn The same characters also happen to be the ones used for the Japanese term that refers to the changing of foliage colour in the autumn which should provide a reference for how important and representative momiji leaves are to the fall season in Japan As you ll see in the photos in this post though momiji leaves can take on an entire gamut of hues making for spectacular displays of colour My other favourite leaves are those of the ginkgo tree a plant that is arguably a living fossil having first appeared in the fossil record some 250 million years ago Ginkgo trees also have gender So any given tree is either male or female which means it takes at least two to tango Ginkgo nuts the gametophytes of this fascinating plant feature in some cuisine in Japan too They are delicious in small quantities Yellow ginkgo leaves and small brown momiji after rain License image Anyway my few days of R R are over now It s time to get back to
