What color are orcas' eyes?
In short, mostly brown. In long, it's a bit complicated as Killer whales (and for that matter, all cetaceans) have multi coloured eyes! Unlike us humans, who have a singular coloured iris and a white sclera, cetacean eyes come in more flavours. Their iris is circled by a pale ring of varying colour, and the surrounding sclera is more often than not coloured too, sometimes even bi-colored. I have actually been working on a cetacean eye-colour-chart thing so I have some neat illustrations ready.
Tumblr media
Here you can see the components that make up a cetacean's eye. It should be noted though that when relaxed, the eyelids cover much of it, leaving almost only the iris visible. As an example: a Harbour porpoise (Phocoena phocoena). On the left a clear view of the eye in its totality; on the right as visible in life.
Tumblr media
Onto the whale in question. All cetaceans have beautiful brown irises: in many it is an unbelievably rich reddish hue when sunlight hits it directly. In shadow or underwater it looks more subdued though. Then comes the pale ring which in Killer whales is quite variable: in some animals it is very pale, almost white, while others have beautiful bright blue rings. The sclera appears two-toned in blackfish as far as I've seen. Killer whales have a rather modest dark brown area of sclera around the iris-pale-ring-combo, with the surrounding "base" sclera reddish pink. For comparison, False killer whales (Pseudorca crassidens) have a bit more substantive dark brown sclera area, with the surrounding sclera a striking bright red.
I hope this answers your question! This makes me want to finish this chart haha so maybe that'll come soon-ish in its totality.

Critter fact #52:

The Vaquita (Phocoena sinus) is the most endangered animal on the planet. It is currently the smallest living cetacean, and is endendemic to the northern part of the Gulf of California.

Dzharylhach National Park
A beautiful natural reserve in Ukraine
Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media Tumblr media
A couple of facts about the reserve (sourced from various websites, i.e. tourist guides, interviews with researchers, news articles etc and rewritten by me; if you notice false information, please, let me know)
Dzharylhach Natural Reserve is an island in the South of Ukraine (Kherson region), surrounded by the Azov Sea.
The territory of the island is uninhabited by people
There is a lighthouse on the island, and a legend related to it: some say that the lighthouse was built by one of the students of Gustave Eiffel (yup, the renown creator of the Eiffel Tower). Is it true? Who knows :) Feel free to explore the topic further!
Dzharylhach is home to wild animals and endangered (worldwide or locally) species: ~20 types of rare insects, ~69 species of birds from the Red Book of Ukraine, ~15 types of mammals. Some of those include: Chrysopogon gryllus (plant), Steppe viper (Vipera ursinii), Caspian whipsnake (Dolichophis caspius), Blotched snake (Elaphe sauromates), Harbour Porpoise (Phocoena phocoena) (threatened in the Black Sea region), and others.
Sadly, after the russian invasion of Ukraine (2022) the island was occupied by russian troops. it is reported that Russians have destroyed the flora and fauna of the island by using it as one of their military bases (several fires broke out there as well). 100% accurate assessment of the damage to the reserve cannot be carried out right now due to occupation; prospects for the future restorement of the natural reserve remain uncertain.

Vaquita - Phocoena sinus endangered species
(not rlly fun facts)
Fun Fact 1 : from 2011 to 2016 alone, 90% of the vaquita population has dropped and now the estimated number for 2023 is 10-13 vaquitas (they live in Mexico). Before this in 1997 there was 600 vaquitas.(;_;)
Fun Fact 2 : A vaquita is a type of porpoise. Porpoises are one of the smallest members of the cetacean familv which includes dolohins and whales. Man species of porpoise are barely studied and most of what we know of them comes from when they are found washed up.
(´;Д;`)
Fun Fact 3 : The vaquita population has been declining because of illegal fishing with gillnets for an endangered fish called totoaba which is wanted for its swim bladder. When gillnets are used many species get caught in it by accident and get tangled while trying to escape, this happens to sea turtles a lot.。゚(゚´Д`゚)゚。
Post dedicated to the Vaquita (srry i didn’t realize i missed a day)

The group of mammals that includes whales, dolphins and porpoises is call Cetacea, and the subject of my recent oil painting is the world’s smallest Cetacean, the Vaquita (Phocoena sinus), little porpoise that, at maturity, is less than five feet long.  The Vaquita is found only in the waters at the northern end of the Gulf of California and is critically endangered, down to about ten to twenty individual animals left, as of earlier this year.  Its existence as a species was first established in 1958, based on the structure of skulls retrieved from dead individuals found on the beach, but it was only in 1985 that its external appearance was finally described.  “Vaquita” means “little cow” in Spanish. No other marine mammal has such a small range.
The main threat to the species is another animal species found only in the Gulf of California, a large drum fish called the Totoaba (Totoaba macdonaldi), itself now an endangered species. I have shown a couple of them in the background. The problem is a demand by an Asian market for the swim bladders and meat of the Totoaba. The nets used to catch the fish caught, entangled drowned the Vaquitas. The bladders are a delicacy in Chinese cuisine, and the bladders are mistakenly credited with treating fertility, circulatory and skin problems. The demand for Totoaba commenced a century ago, after a native Chinese fish, the Chinese Bahaba (Bahaba taipingensis), also known as the Giant Yellow Croaker, as nearly exterminated. It is still critically endangered, with both fish species facing other threats captured by the catch-all rubric, environmental degradation.
A major threat to the north end of the Gulf of California’s marine life is all too well known: the salinity of this region, surrounded by land, has for thousands of years been determined by the flow of fresh water from the once mighty Colorado River, at the “top end” of the sea.  But the water of that river, whose force carved the Grand Canyon upriver, and could fill the aquifer behind Hoover Dam, all gets drained off for farming, kitchen taps, golf courses, lawns, gardens, car washes and multiple other human uses before reaching the sea, while at the same time massively unprecedented draught grips the region. 
Both Vaquita and Totoaba are protected, and work is underway to commercially raise the latter in fish farms, which potentially carry their own environmental risks. But there is not only poaching, but net captures of other marine life that still threaten both the Vaquita and the Totoaba.  The latter has good survival potential but it is extremely frustrating to those of us who care that there seems really to be nothing that can be done to prevent the extinction of the Vaquita at some future point in the current century.  It’s far from my best painting; I wanted to convey a sense of tranquility to symbolize the harmonization within nature even with its predatory and competitive nature whereas I perhaps should have tried a more stark or dramatic effect, perhaps the better to reflect my frustrations over my inability to reduce the damage we do to others, other species often unknown to most people, but I felt that at least I should paint its picture, chasing squid in the shallows, an imagined scene based on a reality soon to leave us.
The painting is in oils on compressed hardboard and is 24 by 30 inches in size.
