The Most Beautiful Bivalve In The World – Pedum spondyloideum

The Coral scallop (Pedum spondyloideum) is the most beautiful animal I have encountered underwater. The delicate bivalve lives within the hard coral its entire life.

  • Scientific name: Pedum spondyloideum
  • Distribution:  Ryukyu Islands
  • Habitat:  Hard corals in shallow water
  • Diet: Filter feeders
  • Average Size:  35mm-55mm

What purpose do they serve in the ecosystem? Researchers believe these beautiful bivalves serve a beneficial function among hard corals.

  • Provide circulation for feeding coral
  • Defend the host by expelling water when threatened by corallivorous marine life

The hard coral provides the bivalve with support and protection. The shell is very thin and fragile. Below is a great example of a protected piece of coral with an army of coral scallops.

The crown of thorns starfish is the most devesting predator of the coral. If the coral (host) dies the bivalve will not survive.

The coral scallop is very thin and fragile. The living animal is much more beautiful than the protective shell it produces. These specimens were given to me by a fellow researcher.

Featured Artist | CJ French

 

CJ French is an amazing artist inspired by nature. I have collaborated with her on three separate occasions. The first was the Turtle conservation art show, the second was  Sharks and Rays fundraiser and the third was the Coral Conservation art show. All three events were held at the Okinawa Brewing Company and were a huge success!  She is an amazing musician as well, her band performed at the fundraisers.

 Purpose of the art shows:  To educate others about these amazing creatures and the major threats they are facing. To donate some of the profits for the art pieces to conservation organizations.

CJ’s Story

It all started when I was a toddler. I was holding an orange crayon after coloring on the wallpaper in my bedroom when my parents walked into the room and found me holding it behind my back. In fear of getting into trouble when they asked who had done it I blamed my sister.  From that moment I was given a sketchbook to perform my works of art. This began my journey of pencil sketching.

When I was 14 I decided I wanted to use a much bigger canvas. My parents purchased paint and allowed me to paint my first mural on the fire escape in our house. I found happiness during the night hours with the floodlight beaming down into the fire escape as I painted onto my first concrete canvas.  Additionally, I was enrolled in art classes during this time which further developed my love for various mediums as I started experimenting with watercolor and textures in my paintings.

In college, my artwork took a backburner to my studies but when time allowed, I would resort back to sketching on a pad with pencil-typically on my notes and outlines during classes. This continued into adulthood. Sometimes ideas for new pieces were born from sketches. I would fill my apartment with acrylic paintings but only viewed art as a hobby.

As an adult with two children (4 and 5 years old), my love for acrylic painting was reunited when the three of us worked on a piece together. I asked them to help me pick the colors they see when they open their eyes in the ocean. From there, we completed our first abstract ocean-inspired piece together which still hangs in our bedroom.

I painted pieces for the children’s bedrooms depending on what they were into at the time, whether it be princesses or transformers. All the while completing works of art on my surfboards as an outlet to continually use new mediums-this time it was Posca pens on surfboards and skateboards.

When we finally made the move to Okinawa and I was fortunate enough to meet fellow artists, I was encouraged to provide artwork for OISTs art show with profit donations benefiting marine conservation efforts. Finally, my passion for art collided with my love for the ocean! The first art show was to benefit sea turtle conservation. Much to my surprise, every piece submitted had sold. I was so thankful to find a community that was encouraging and inspiring! I have continued to donate a portion of every one of my pieces to marine conservation.

Most recently when I saw the call for artists to paint the OkiLife building, I immediately jumped at the opportunity to paint a mural again. Completing this mural with the artists I had met on the island was such a great experience. Although we all have different styles and techniques, the artwork came together organically. Currently, my artwork is on display at the OkiLife building.  I will continue to explore the range of mediums, as evidenced by the displays.  You can find everything ranging from a surfboard with Posca pens, a skateboard with acrylics, and a few acrylics on canvas pieces as well.

I had never imagined my artwork would be shared with the public but I am beyond grateful for the supportive community that inspires and encourages one another bound together by their love of artful expression.

Spiders, Webs and Warning Signs – Okinawa, Japan

In the last few months, I have been searching for spiders with unique web designs. The stabilimentum serves a different function for different species of spiders. The Oval St. Andrew’s Cross Spider is a master at designing its web with an obvious warning sign. Researchers believe the X-like stabilimentum serves as a warning to prevent birds from destroying the web. 

Theories why orb-weavers have specialized web decorations 

  • Stabilize the web
  • Make the spider look much larger
  • Disguise itself / Camouflage
  • lure prey in (ultraviolet light)
  • Serve as a warning sign for large birds
  • An attractive piece of art/lure in a mate
Argiope aemula

Argiope aemula -X-factor

Octonoba yaeyamensis has a very unique stabilimentum. The pattern reminds me of the mysterious design the Amami pufferfish constructs to lure in the female.

What purpose does this design serve?

  • Hide under the web /disguise itself
  • Beautiful design to lure in a mate or insects
  • Deterrent- scare off larger animals to prevent web damage

Octonoba yaeyamensis

When I first found this spider it was hiding under the stabilimentum. It serves as camouflage and protection from ultraviolet light (sunblock strand). I found it in the open sunlight on a branching leaf.

Spider web prism

I have always wondered if spiders are unknown musicians. Their web has to produce some type of sound frequency. The tension of the web gently plucked by the spider or just blowing in the wind.

Do spiders use attractive frequencies to lure in insects or mates?

The next step is to photograph the x-shaped stabilimentum under ultraviolet light. stay tuned to see my results.

Fish Populations Decline At Maeda Point – Not A Good Sign!

I originally got SCUBA certified at Maeda Misaki in 1992. I have seen this popular snorkeling location drastically change over the years with the increase in tourism. Meada point is now a high traffic area, literally thousands of people enter the water on a given weekend.

If you have ever been to maeda point you have seen the beautiful schools of Teira batfish (Platax teira). In the late 90’s there were massive schools of hundreds of these beautiful fish. Below is an old photograph I found in my photo album. This was a common site back in the 90’s.

Teira batfish at Maeda misaki

In 2017, I noticed that populations started declining.

Schools of batfish

2018-2019, I started seeing numbers decline to less than twenty individuals. July 2019, I went to the same location on three different days and didn’t see any batfish.

Wide angle macro

These fish are a huge tourist attraction. What could have caused the decline of the batfish populations? Possible reasons for decline:
  • Feeding the batfish man-made products
  • Noise pollution from an increase in boat traffic
  • Moved on to a safer location
  • Overfishing
  • Contaminates entering the water – sunblock, shampoo, perfume and urine
IMG_3955

Fu (wheat gluten)

In the past, guides would feed the fish sausage and bread. In recent years many local companies switched over to Fu (wheat gluten). It’s much cheeper than fish sausage.  Kilos of Fu enter the water for fish consumption on a given week at Maeda point. Could this gluten based product be good for the fish? Why you should not feed wild animals:
  • Interfere’s with their natural diet and feeding cycle
  • Makes the fish more vulnarable to predators
  • Reef algae overgrowth due to the fish being full
  • Increase’s your chance of getting bitten
Sometimes, I see plastic bags filled will remnants of fish food floating on the surface of the water. With the increase in tourism, I am finding more trash left behind at Maeda Point. This is a photograph I took recently at Maeda point. A collector urchin (Tripneustes gratilla) is covering up with discarded sausage wrapper.

This is one of my favorite photographs taken at Maeda Point.

Hopefully the teira batfish populations are not a blur left behind.

Searching for the Amami Oshima Frog by Shawn Miller

The Amami Oshima frog is featured in National Geographic this month for the series ” Wildlife As Canon Sees It “

IMG_4077

The Amami Oshima Frog (Odorrana splendida) is considered the most beautiful frog found in Japan. It is only found on Amami Island and is listed as an endangered species. It is one of the many endemic species facing extinction due to habitat loss. This protected species is designated as a living national treasure of Okinawa.

  • Scientific name: Odorrana splendida
  • Distribution:  Amami Island
  • Habitat:  Forest streams 
  • Diet:  Insects, worms, and millipedes
  • Average Size:  90mm-110mm

Odorrano splendida 6 Amami Island

We were on the Island for a short period of time but managed to see eight Amami Oshima frogs. It rained the entire time but that didn’t stop us, we were on the mission to find the endemic species. I explored the island with Zoologist Valdimir Dinets and bat Scientist Jason Preble.  We were fortunate to see the Amami rabbit, Amami Jay, Owston’s woodpecker, Hime habu, Ryukyu robin, Amami woodcock, Amami Spiny rat, Otton frog, Amami tip-nosed frog, Whip scorpion, Wood pigeon, Coral snake, Crocodile newt and the banded ground gecko endemic to Tokunoshima. Below are some of my favorite images of the Amami Oshima frog in it’s natural habitat.
