I know nothing about you pingoes but I see Eva and I see you on my dash constantly you are my friend and I love you /p

YAYYY THANK YOU !!!!!!! :] i appreciate your oceanposting too im glad to have another fish-loving friend on this website

Opah or Moonfish (Lampris guttatus), family Lampridae, order Lampriformes, found in oceans around the world

This fish is capable of whole body endothermy (warm-bloodedness).

This is the only fish that is known to be capable of this. Some other fishes, like tunas and some sharks, are capable of "regional endothermy".

Taxonomy Tournament: Fish

Lampriformes. This order is made up of opahs (also known as moonfish or sunfish) and their relatives, such as oarfish, crestfishes, and ribbonfishes

Stomiiformes. This order is made up of deep-sea fishes. It includes dragonfishes, loosejaws, viperfishes, and bristlemouths, the most populated family of vertebrates, with population numbering in the hundreds of trillions to quadrillions.

Opawh

Yet another cattofish because people keep suggesting fish to me and I keep listening. Opah (or moonfish) is the common name given to fish in the small family Lampridae. They are unique among fish in that they can maintain the core of their body up to 5 °C higher than the surrounding water. Very little else is known of their biology and ecology but they are thought to be solitary and live out in the open ocean at depths of 50 to 500 m.

FISH KIN: @lampriformity, your fish kin is...

Lampris guttatus, the Opah! Now, I do personally think it's cheating to assign you a lampriforme, because like. It is literally in your name, but I just couldn't resist this guy- and how could I? The Opah is a discoid pelagic ray-finned fish closely related to the Oarfish, probably one of the best-known Lampriformes! The Lampriformes shaped like the Opah are called "bathysomes", where the longer, slimmer ones are called "taeniosomes"- translating to "deep-bodied" and "ribbon-bodied" respectively! While the Opah is kinda an odd-man-out among the Lampriformes, given its unusual shape, the fossil record shows that MOST prehistoric Lampriformes were bathysomes- and it's only relatively recently that they started getting stretched longer! Thank you so much for your donation!

finally getting around to working on the little beans

@lampriformity @sylph--co @vivienna-vivid your guys were the first 3 done! yippee!!

the rest of them are getting finished :D 👍

ok i drew dennis as an oarfish. when ur girlfriend is a large, greatly elongated, pelagic lampriform fish belonging to the small family Regalecidae

[rostbef]

you'll be scrolling through tumblr reading some random interesting post about some rare species of fish or whatever and at the bottom of it you'll suddenly see someone saying "pelagic lampriform fish heritage post"

Animal Crossing Fish - Explained #200

Brought to you by a marine biologist and...holy hell, 200?!!

CLICK HERE FOR THE AC FISH EXPLAINED MASTERPOST!

Well, I’d like to commemorate this momentous occasion by covering a really interesting creature that was featured in AC Pocket Camp and that is the Opah. I’m a little biased here because I just love weird fish, especially deep sea species we don’t really know a lot about. It’s about the mystery. So, I’ll do my best to cover this amazing thing. If you want to know why we don’t have a lot of information into deep sea fish, check out my coverage of ACNH’s museum tour of the deep sea tank.

The Opah appeared in AC Pocket Camp for Fishing Tourney 40, which occurred in July 2021. Like I mentioned in the last entry, it appears that ACPC is less concerned with the actual temperature range or habitat of the fish it chooses for what events. The Opah is considered a deep-sea species, or at least an open ocean species that just doesn’t come close to land. It often lives at depths where the water temperature is around 4º C (about 39º F), which is, ya know, not a balmy summer temperature. Although Opahs as a group have a cosmopolitan distribution (aka they are found all around the world, including tropical areas) they tend to stay deep where the water is cool and sunlight can’t reach.

Anyway, the Opah is a pretty unique fish. It belongs to the Order Lampriformes, a small group of fish that include mostly deep-sea and pelagic species. The Order’s name comes from the Opah’s round shape and brilliantly-colored fins and skin, though most Lamprids are more long and slender, with most fish in the Order belonging to the “ribbonfish” clade, for which the infamous Oarfish is a part. That being said, Opahs exist apart from their cousins in the Lampridae family, which only houses one Genus, Lampris. For much of the time we’ve known that Opahs existed, we accepted that there were two species within this Genus. However, in recent years, Lampris guttatus, the comsopolitan species, has been broken up so that there are now six species with more limited ranges. As I’m sure AC Pocket Camp wouldn’t recognize this, not to mention the study occurred in 2018 after ACPC was released, I’m pretty confident this is simply Lampris guttatus, or the (original) Opah.

So, despite the fact they look a bit goofy and fat, these fish are actually really fast and exhibit endothermy, or warm-bloodedness. In fact, the Opah is the only fish we’ve discovered so far that has whole-body endothermy, in which all of its internal organs and muscles are kept at temperatures higher than the surrounding water. (Please note, this is still unlike birds and mammals that keep their warmth at a constant temperature - the Opah’s body temp still fluctuates.)  On top of that, Opah also exhibit regional endothermy, or the act of keeping some parts of the body warmer than others. This type of endothermy is more akin to billfish, tuna, and lamnid sharks (like the great white, porbeagle, salmon, and makos). This type of endothermy usually keeps the eyes, brain, and swimming muscles at an elevated temperature which helps these fish remain active hunters in colder waters. So, unlike most deep-sea fish, the Opah doesn’t just float around in the dark waiting for prey to come to it - it has the power and energy to seek out and chase down its food, which often includes squid and smaller fish.

And there you have it. Fascinating stuff, no?

An absolutely beautiful specimen of, what looks like, a unicorn crestfish (Eumecichthys fiski). This is a member of the lampriform order, and thus is a relative of the spectacular giant oarfish.
