The kissing of sea slugs. Reminds me of Gustav Klimt paintings. Elysia viridis, commonly known as the solar-powered sea slug or sap-sucking slug, is uniquely distinguished by its rare ability to steal plant-like cellular machinery from the algae it eats and use it to perform photosynthesis.
It’s so happy to announce my paper entitled “Density-dependent courtship interference by neighbors in fiddler crabs: Increased male-male competition but reduced female choosiness at high population density“ has been published in behavioral ecology and sociobiology! link.springer.com/article/10.1...
Density-dependent courtship interference by neighbors in fiddler crabs: Increased male-male competition but reduced female choosiness at high population density - Behavioral Ecology and Sociobiology
High population density increases the proportion of unsuccessful males in both male-male competition and female choice contexts. This prediction assumes that these components of sexual selection opera...

Dear enemy phenomenon in fiddler crabs: escalation of fights with unfamiliar individuals rather than familiar neighbours
In territorial animals, fights against strangers are often more aggressive than those against neighbours. This is called the ‘dear enemy’ phenomenon a…

🚨 Exciting new crab preprint! A Japanese team found that sideways walking only evolved once! Maybe carcinization itself is necessary but not sufficient to go sideways? When it's lost, the species that go forward have alternate anti predation behaviors. 🧪🦑🦀 www.biorxiv.org/content/10.1...
Evolution of sideways locomotion in crabs
The evolutionary change in the mode of locomotion is often a major evolutionary event, triggering diversification. Sideways locomotion is a defining feature of true crabs (Brachyura) and may have cont...

Parasite aggregations: Females attract conspecific males to the hosts in the ectoparasitic isopod Onisocryptus ovalis
For symbionts of marine invertebrates, migration between hosts for mate-searching entails various ecological difficulties. Aggregation in hosts is a b…
