Hi everyone. I felt really dejected for a long time about the state of science communication on Twitter, and was reluctant to give things a try on yet another new platform. I’m so touched by the support everyone has shown so let’s give this one last go, as KaiTheFishGuy on Blue Sky!

An amazing talk on mesophotic fish given by @kaithefishguy.bsky.social 😱 at #IPFC12 in Taiwan. So many new records for Australia from the deep(er) sea😍

Yes I use all my annual leave every year to risk it all for pictures of literal INSECTS.
And I love it!

Trogonoptera brookiana, Rajah Brooke’s Birdwing.
Malaysia’s national butterfly is quite a thing of beauty. Its black wings with emerald green feather-like markings, bright red head, and blue wing accents isn’t even its most remarkable feature. It’s probably the fact that it measures close to 15 cm

The two specimens I have on loan here, including one paratype, are invaluable pieces of natural history.

This is one of the most exciting loans I’ve ever unpacked. There are only seven specimens of Prognathodes guyotensis known from collections worldwide; three specimens in the type series, all from the Kyushu-Palau Ridge, and a further four from scattered localities across the Indo-Pacific.

Last weekend I was fortunate to encounter two female Yellow Jewel butterflies (Hypochrysops byzos) along a creek line about 45 minutes from Canberra.
This is a very elusive and one of the more difficult of the Australian Jewels to find, so finding bro one but two was an extra special treat.

Watching The Boys and there’s a fish I named in one of the scenes!
Cirrhilabrus cyanogularis, the Blue-throat Fairy Wrasse. I described this species in 2018!
