I’ll be posting this week from the International Sea Turtle Society symposium in Hawai’i Day 1 was full of fantastic workshops: in the morning I attended one about applying for research permits to study turtles, and my afternoon was all about sea turtle epibionts 🌊🐢 #ISTS44 #ISTS2026 #seaturtle
A selfie in front of the conference welcome sign. The logo shows a sea turtle at the water’s surface with a volcano in the background. Across the volcano is the word “Kaiāulu”, which is a Hawaiian word for community/neighborhood/village. The theme reflects the close-knit nature of the people who work with sea turtles -  celebrating how we support one another to coordinate conservation, science, and management around the world.

The pronunciation of Kaiāulu in English is roughly "kai-ah-oo-loo": Kai sounds like "kite" without the "t", ā is a long "ah" sound, ulu is like "oo-loo". So, the full pronunciation is "kai-AH-oo-loo" with emphasis on the "AH" syllable.

Having a full suite of reference genomes allows for all kinds of cool analyses. Look at how much synteny there is among the sea turtles (first 6 shown, I don't know where Kemp's ran off to). That's despite the fact that leatherbacks (in blue) diverged from the other species >50 million years ago!
Figure 2 from Arantes et al. 2025 shows a gene synteny plot for 6 sea turtle species, along with the Chinese pond turtle, Goode's thornscrub tortoise, European pond turtle, red-eared slider, and Mississippi diamondback terrapin. There is extremely high synteny among the sea turtle species. Below is a phylogeny with estimated divergence times for each species above (plus a few more). Leatherbacks diverged from the hard-shelled sea turtles in the ~late cretaceous.
