Mites that kind of look like Opiliones (hence the name). Found all over tropical and subtropical habitats worldwide, poorly studied. These were the first I've ever seen alive! From south of La Paz, Baja California Sur, Mexico. This is Neocarus bajacalifornicus.02 Mar 2024 15:26 +0000at://did:plc:2flnjsva2mesftsliv2zctyx/app.bsky.feed.post/3kmpwis2sut2uhttps://bsky.app/profile/sderkarabetian.bsky.social/post/3kgqxlor66h27Phrynus asperatipes from south of La Paz, Baja California Sur.

Found in a woody debris-covered rock pile at the base of a large eucalyptus tree. The bright yellow spot is the ozopore, the opening for the chemical defense gland. #Opiliones25 Oct 2023 02:56 +0000at://did:plc:2flnjsva2mesftsliv2zctyx/app.bsky.feed.post/3kckaho3qwc2ahttps://bsky.app/profile/sderkarabetian.bsky.social/post/3kcbs7nwgqe2c#Arachtober Scorpion face.

Seen during a rainforest night walk in Crater Lakes NP. Amazing colors on this one. #Arachtober05 Oct 2023 01:49 +0000at://did:plc:2flnjsva2mesftsliv2zctyx/app.bsky.feed.post/3kaxtf4ajdw2yhttps://bsky.app/profile/sderkarabetian.bsky.social/post/3kapltpryf424It's #Arachtober !! To start off, this is an undescribed species in an undescribed genus of Triaenonychidae from northern Queensland, AU. We (@invertebrained and I) found only two at this site, they were a bit hard to find.01 Oct 2023 19:13 +0000at://did:plc:2flnjsva2mesftsliv2zctyx/app.bsky.feed.post/3kapltpryf424https://bsky.app/profile/sderkarabetian.bsky.social/post/3k5zubx7sdr2vDuring fieldwork in Tasmania earlier this year, found this velvet worm, Tasmanipatus barretti, in one of the best woodpiles I've ever looked through. Seems a little shy. A rare species, listed as vulnerable. With permit. What a pleasure seeing this.

Do you like Opiliones? I post (mostly) Opiliones, my macro photos, and research. I’m an arachnologist, systematist, and evolutionary biologist. Expert in Opiliones. (soon to be) Curator of Entomology at the San Diego Natural History Museum. Also, Opiliones.19 Aug 2023 17:46 +0000at://did:plc:2flnjsva2mesftsliv2zctyx/app.bsky.feed.post/3k5dcx5pbbn2i
