…and of course the scenery was stunning! NZ is a great place to live and work.

Nights were our primary focus, but we made the most of the daylight to sample other parts of the system for stable isotope work

New Zealand’s Fiords are a fantastic spot to study mesopelagic species! We just returned from a bucket list expedition on RV Polaris, and with buckets full of “lanternfish-adjacent” pearlsides.

Hi Chris - I'm not sure, but I think there was a suggestion that it could have been an early life stage of the fangtooth, Anoplogaster cornuta. The team also captured the adults of this species in the nets.

Critters from the deep sea never cease to amaze me! They really are "textbook exemplars" of adaptation. Lanternfish are, of course, the coolest--but other critters are neat too! 🧵(3/3)

"The Great Migration" voyage (TAN2412) was an amazing success by any metric. Big thanks to Voyage Leader Amandine Sabadal, fish experts Andrew Stewart and Mike Miller, and all the other wonderful participants and crew! 🧵 (2/3)

"The Great Migration" voyage (TAN2412) has wrapped, and our team successfully sampled 1575 myctophids comprising 33 species from a latitudinal gradient spanning New Zealand to New Caledonia. A treasure trove for our future work! 🧵(1/3)

Its "D-Day" for the "The Great Migration" TAN2412 voyage of the RV Tangaroa, and our lab members Niamh Smith and Alisha Gill are aboard and geared up to catch lanternfish for the next 35 days! - super excited to follow their exploits! @vicuniwgtn.bsky.social @marsdenfund.bsky.social

This may be the first example of environmental sex determination driven by moonlight! Spawning patterns of sixbar adults closely resemble birthdates of males. Selection patterns suggest adults may spawn on new moons to make males, full moons to make females. Super cool! (5/6)

“What doesn’t kill you, makes you stronger”. Most sixbars born on a new moon will die. But for survivors, their developmental plasticity shapes future traits that position new moon babies at the top of a dominance hierarchy. (4/6)

Jeff Shima @drjeffshima.bsky.social · 08/08/2024

Why do sixbar wrasse spawn the most eggs at the new moon—a time that effectively kills more of their offspring? We suspect compensatory benefits later in life. We know offspring have developmental plasticity, and also that new moon birthdates benefit larval growth… (2/6)

Do fish use the moon to manipulate the sex of their offspring? See our latest paper in Proceedings of the Royal Society B! (1/6) royalsocietypublishing.org/doi/10.1098/...

We’re ‘shining a light on lanternfish’ thanks to a new grant from the Marsden Fund How might lanternfish contribute to the global carbon cycle? How might they shape life histories, population dynamics, and productivity in coastal ecosystems? @marsdenfund.bsky.social
