Searching For The Strawberry Conch in Okinawa By Shawn Miller

The Strawberry conch (Strombus luhuanus) is a popular food source found on the Island of Okinawa. Locals know as uchinanchu (sea people) search for this marine snail during extreme low tides. The sweet tasting meat of the conch shell is sought after during the summer months.

After harvesting and consuming the conch meat, the shells are giving back to the ocean in large piles. This will provide shelter for marine-based hermit crabs and eventually stabilize the sediment.

Land hermit crabs are often found next to these onshore shell piles, scavenging on conch meat remains.

The beautiful conch shells are commonly confused with the hazardous cone shells. The main difference is that conch shells have a stromboid notch. A small side slit or indentation which allows the animal to see while moving.  The conch shells movement is much different as well, they travel using a jumping style movement instead of a steady crawling motion.

The animal has strange eyes located at the end of long eye stalks.  The eyes color is usually a vibrant green, yellow and orange combination.

Take a close look at this strawberry conch below. What do you see?   I see two extra eyes poking out of the stromboid notch.  The marine snail naturally has two eyes, not four.

What is the cause of this?  Could this deformity be caused by nutritional deficiencies, a genetic disorder or pollution?

Regardless of the cause, I hope these images will inspire people to care more about nature and make a positive impact in the environment.  We all depend on the ocean in some form. Let’s work together to make a difference.

Hummingbirds on Okinawa By Shawn Miller

I’m sorry to disappoint you but we do not have any hummingbirds on Okinawa.  We do have hawk moths that resemble hummingbirds. The hawk moths are also called hummingbird moths. They are extremely fast and challenging to photograph.

I used a slow shutter speed to convey motion in the wings of the Hummingbird hawk moth (Macroglossum corythus)

I often find the insects feeding early morning and or late in the evening. They feed using a long proboscis to drink the nectar.

They are hard to see since they are small (35 -45mm) and move extremely fast. They can be heard creating a humming sound as they fly by. They hover for a short period of time collecting the nectar and move on to the next flower.

The Convolvulus hawk moth ( Agrius convolvuli ) is the largest hawk moth I have seen on Okinawa.
