People often ask me what is the purpose of conservation photography? Having the ability to affect some form of positive change in the environment and make a global difference with the photographs. Hopefully, the images will inspire people to care more about nature and make a positive difference in the environment.

The Hallowell’s tree frog – Okinawa

The Hallowell’s tree frog ( Hyla hallowellii ) is found on Okinawa, Amami and Tokunoshima Island.

  • Scientific name: Hyla hallowellii
  • Common name: Hallowell’s tree frog
  • Distribution: Ryukyu Islands
  • Habitat: Forests, grassy areas and farm fields near water.
  • Diet: Insects
  • Average size: 30mm-40mm

They are easy to locate during mating season. The male produces a fairly high pitch squeak sound over and over.

The Light & Motion Stella 2000 rocks part 1 – Okinawa, Japan

The Stella 2000 offers lightweight professional lighting for photographers and videographers. It delivers 2000 lumens of beautiful wide light on high power. It is waterproof to a depth of 100 meters and extremely durable.

Stella 2000 waterproof lighting

My favorite features of the Stella 2000

  • Waterproof to 100 meters
  • Can be mounted on the camera hot-shoe, light stand,  loc-line arms or ball mounts.
  • Quick adjustable power output control
  • Fast charging and the ability to use the light when it’s charging

I tested the Stella 2000 in the humid jungle and on the shorelines of northern Okinawa. I used it as a spotting light, hiking light, camera modeling light and video light. I tested the light with the 120-beam angle with no modifiers, with custom-made soft-boxes attached, studio umbrellas and with the combination of on-off camera flash.

I concentrated on the reptiles, amphibians and land crabs of northern Okinawa. Below are some of my favorite photographs.

Crabs With Beach Trash Homes – Okinawa, Japan

  Crabs with beach trash homes is a series I am currently working on. I photograph Blueberry hermit crabs (Coenobita purpureus) that have begun to use beach trash as their home. The crabs are photographed in their natural environment and also on white for the Meet Your Neighbours global biodiversity project. The images are used for environmental awareness and educational purposes.

 Blueberry hermit crabs are commonly found on local beaches in Okinawa. Most crabs are blue but occasionally have color variations of purple, pink, orange and or gray. They prefer to have a seashell as a protective home but when no shell is available they adapt.

Before plastic caps filled our shorelines, hermit crabs adapted using tree nuts if no shells were available.

It’s becoming more common to find crabs with beach trash homes.  I have friends combing local beaches in search of more crabs for my series. While these are cute images, our trash is becoming a serious problem to the ocean and the animals that call the shoreline home. I often find hermit crabs using a variety of plastic caps from twist top pet bottles, laundry detergent containers, small propane tanks, sports water bottles and beauty supplies.

Possible reason why Blueberry crabs adapt with beach trash
  • Limited number of available shells causing them to make due with the best homes they can find. This is a good example of adaptive behavior.

Hermit crabs are very social animals and often fight over shells. Having a protective lightweight shell that covers the abdomen (soft parts of the animal) is crucial for survival.

Hermit crabs are scavengers and take advantage of any food washed ashore. They mainly feed on dead fish, barnacles, other crabs, algae, insects, plants, fruit and various seeds. The screw pine (Pandanus odifer) is one of their favorite foods. I imagine long ago these vital plants lined our shorelines in abundance. Numbers are decreasing due to deforestation.

Eventually the fruit drops to the ground and the sweet smell attracts the hermit crabs

The hermit crabs feed on the the fresh keys and help with seed dispersal. They both benefit in this relationship.  The Pandanus tree provides shelter, shade, food for the hermit crabs.

Eventually the keys dry, turn brown and litter the local beaches. The dispersed keys provide a perfect environment for hermit crabs to blend in with.

Hermit crabs prefer to be in a shell that protects the entire body from predators. Sometimes they have to temporarily adapt with a much smaller shell.  The retracted hermit crab tightens up to protect itself.  Ball up, play dead and blend into the environment, minimizing the risk of being preyed upon.

Could this be a form of masquerading or just coincidence ?  It resembles (mimics) the shape of the screw pine seed to possibly avoid detection from potential predators.

I also photograph the hermit crabs using a dedicated macro lens. I mainly use the Canon 60 mm or 100 mm macro lens to concentrate on the subject. These crabs are fairly small and  it’s important to have a lens that will focus close and deliver high quality sharpness.

School project  ” Crabs with beach trash homes ”  My family and I collected trash on a  local beach in Onna village. This is just a small portion of our beach trash findings.  The kids did a great job creating a project with impact.
