"For fiddler #crabs, vibrational signals are a crucial part of their courtship routines... males with larger claws produced higher-energy seismic signals, with higher amplitude drumming spikes. This appears to prevent the male from being dishonest about their size"

Love songs in the sand: Researchers listen in to fiddler crab courtship

For the first time, a study led by University of Oxford researchers has listened in to the fascinating courtship displays of fiddler crabs using geophones. The findings, published in the Journal of Experimental Biology, provide new insights into how the animals communicate effectively on the noisy seashore.

This poem is a story about the survival of a river’s inhabitants. I took most of the photos on the St. Johns River. The story combines two Asian forms: Ki Shô Ten Khetsu and Haiku.

I used Zona AI music to generate the music. Here is what I requested: “Japanese traditional music, haiku, shakuhachi, koto, male and female duet.”

This pattern would match that of two other #fiddlercrabs where a species with a broad Pacific range was found to contain a cryptic species restricted to the Fiji to French Polynesia region, Gelasimus excisa vs. Gelasimus jocelynae and Austruca citrus vs. Austruca perplexa.

An #introduction

I'm a computational evolutionary biologist and data scientist, Director of the Center for Biological Data Science at Virginia Commonwealth University.

My research is eclectic and covers a broad range of taxa and topics, but often returns to #fiddlercrabs when I get bored.
