We should view Covid the same way as HIV: both destabilize our immune systems.

The science is clear that Covid is “much more than a respiratory virus — it is a complex immunomodulator that targets central defense cells themselves.”

“We may be living through a slow-moving immune decline crisis.”
“Every infection increases the risk for heart attacks, strokes and heart disease; for new-onset diabetes; for cognitive decline and dementia; for deregulating the immune system; and for reactivating viruses like Epstein-Barr or shingles.”

A larval moray eel, Anilao. The skull and spine are obvious, and the gut is also visible along the lower edge for 2/3 of its length. Otherwise, it's transparent.

'Afternoon, Skylings. Time for a nudi for my UW pic! Trinchesia sibogae, a beautiful aeolid. I was lucky to be able to shoot it against blue water, made black by f13-1/100 sec-ISO 100 setttings.
Nudi Retreats, Lembeh, Indonesia, 2006.

Good morning to you, Skylings. It´s VERY hot here, but looking at my UW image collections helps cooling mind and body. This is Hypselodoris roo, from Bali, 2009, a beautiful nudi. Enjoy.

Garden eels always make me smile when I see them on a dive... unfortunately they're very hard to photograph because they're so shy!

Salps are always worth checking out, because they act as shelter or food (or both!) for a whole bunch of other critters. This is a large solo one, but they're also often found in chains or other colonies at different points in their lifecycle.

As a bit of relief from , here is a squid from Anilao. No idea what sort, alas.

Another dive at Folly Cove a few weeks back. The sand lance were still around, which was lovely. Also found countless gunnels and sculpin again, two zebra lebbeid shrimp, and numerous nudibranchs on the sugar kelp. Nice dive!

I don't think it's widely appreciated how psychedelic clams can be. #marinelife #underwaterphotography

A little nembrotha kubaryana, about 4cm/1.5" long. It's so interesting, how much marine life has vivid reds at depths where there is little or no red light. These diminutive nudis live on a diet of equally tiny sea-squirts. #scuba #underwaterphotography #marinelife

A little chromodoris nudi (colemani I think). I like this photo for two reasons: 1) I got the closest rhinophore in focus - this is harder than it looks! 2) the soft coral on the left (some type of Heteroxenia?) is absolutely crawling with brittle stars. #scuba #marinelife #underwaterphotography

This was a good find, a harlequin swimming crab (Lissocarcinus laevis). Don't be fooled by the name; they are found almost exclusively under or on anemones. #scuba #marinelife #underwaterphotography

Getting ready to start the journey back home after 3 weeks away, half for fun, half for work (which was also very fun). I’ll miss being in a place as biodiverse as Okinawa.

Not looking forward to what I’m returning to federally, but on the bright side I should have some positive news to share soon…

A jellyfish from a blackwater dive in Balayan Bay, Anilao. It has a couple of hitch-hikers; a juvenile fish and... I'm not sure what the little orange thing on the right is. Maybe an amphipod?

It’s #worldjellyfishday ! Medusae, that are often considered jellyfish, can be hydroids, or they can be true jellyfish (Scyphozoa). Only true jellyfish have the life stage you can see in this video, the ephyra. #marineplankton 🦑

Deepstaria with a teensy isopod friend. One of my favorite and a jelly we don't come too often across!
