Here it finally is, the full cetacean eye colour info sheet! A long time coming, and an even longer time in the making. I hope that all you cetacean eye curious people will find this one as fascinating as the killer whale eye colour post. It’s a wild world out there! 

Elysia chlorotica, also called the “Eastern Emerald Elysia” is a bright green sacoglossa found along the Atlantic coast of North America that's earned the title of “solar-powered sea slug” for its ability to produce its own energy with sunlight and the chloroplasts that it sucks off of algae.

This unusual process, which is similar to photosynthesis, is known as kleptoplasty. Except for a select number of creatures like the adorable “leaf sheep” Costasiella kuroshimae nudibranch, very few non-plant organisms are capable of the phenomenon.

helloo!! sorry if this is a question u get a lot, do you know any good website to keep up with marine animals news?? and for research??

It's a good question to ask, especially in a world where you have to sift through a lot of misinformation surrounding science (and, to set a good example, I will now be adding references in the notes for my information, particularly if I mention specific studies).

For news, Science.org, SciTechDaily, NewScientist and Nature.com are all websites I have used for keeping up to date with global marine biology news/research although it's always possible to use any news site as long as you ensure they are reliable (e.g. do they include references to research for further reading? does the content of the referenced research match the claims they make in the article? is the site likely to be biased towards a particular viewpoint?)

For research, there are tons of databases storing centuries of marine biology research. Many people like to recommend Google Scholar and I always think it's a good starting point for beginning scientific research but you can't always trust it to be a reliable tool.

ResearchGate, Wiley Online Library, ScienceDirect are all good places for peer-reviewed scientific articles (and I'm sure the people over at @jstor will assure you of the strength of their database too) although, keep in mind, you might have to search through many other databases if you want to dodge paywalls to access full articles.

If anyone else has any other suggestions, feel free to mention them in the notes!

I love this idea.

Can you render the lyrics of Never Gonna Give You Up?

i’ve gotten this request several times now, so for anyone who asked for this after uniquepickles you can just look at this post.

enjoy!:

protein guy analysis:

i was really interested to see how this one would turn out, as it is made up almost entirely of repeated domains (the chorus). unfortunately, as many of you may be quick to point out, the chorus of Rick Astley's 'Never Gonna Give You Up' is not in fact a protein domain, and the only thing repeated are some terrible looking loops. i've even included a second picture to properly show you how flat this terrible protein is.

i thought i understood Levinthal's paradox before starting this blog, but these structures are giving me a newfound appreciation. for those who are unaware, Levinthal's paradox is based on the fact that any given protein can fold into an enormous number of possible conformations, but cannot test all of these within the seconds or less that it takes for a protein to fold into its stable tertiary structure. correct folding is controlled by the primary structure (or, the sequence of amino acids encoding the protein) as well as complex factors including the presence of any chaperones to assist with folding, and the relative abundance of the tRNAs matching specific codons for each amino acid. running this blog makes me think of all the ways this process can fail along the way, and all of the almost correct places a protein can get stuck. this one certainly looks like it failed, but even then its hard to believe this is the shape that stuck.

for those interested, the one beta sheet goes with the line 'you wouldn't get this from any other guy', which does only occur once in the song.

THIS OCTOPUS IS HAVING A NIGHTMARE, SCIENTISTS BELIEVE.

Sleep is a fundamental biological function present in all vertebrates and most invertebrates. Octopuses are really complex animals, displaying active and inactive sleep states similar to those of vertebrates. In particular, octopuses have active sleep states during which they display sequences of camouflage patterns, while remaining relatively quiet and unresponsive to external stimuli. Some scientists have speculated that these states could be analogous to dreaming in mammals.

Now, researchers have recorder what is believing an octopuses having nightmare. During a month, researchers recorded a male Brazilian reef octopus (Octopus insularis), and they detected four brief episodes were identified during which the octopus abruptly emerged from sleep, detached itself from its sleep position, and engaged in antipredator behaviors, despite no predator was present. The longest of these episodes resembled the species-typical response to a predatory attack, suggesting that the animal may have been responding to a negative episodic memory while sleeping.

However, these are just conjectures, as it is hard to be sure, according to scientists, who claim that more studies are needed to ensure that they really are nightmares.

Orchid plants nurture their seedlings via shared underground fungal network, study shows

The Common Spotted Orchid (Dactylorhiza fuchsii) is found all over the U.K. These orchids produce tiny seeds that can be carried anywhere by

The Common Spotted Orchid (Dactylorhiza fuchsii) is found all over the U.K. These orchids produce tiny seeds that can be carried anywhere by the wind, yet they often appear in clumps with small seedlings growing near mature plants. This phenomenon has puzzled ecologists since Darwin's time, with the exact reason remaining a mystery. A new study, led by researchers from the University of Sheffield in collaboration with The University of Manchester, provides the first evidence that early stage orchid seedlings germinate and thrive near to adult plants due to a kind of parental nurture using underground fungal networks. Scientists investigated the idea that fungal networks, known as mycorrhizal networks, act as a direct pathway for established orchid plants to share recently produced sugars with developing seedlings.

My evening was spent making tiktaalik hate, I have to share it somewhere

I thought this feisty little critter was an isopod until I got a closer look. This is a carrion beetle larva, and, as their name suggests, adults and larvae of this insect eat dead animals, maggots that live in carrion, and/or other types of decaying organic matter. I have no idea where this one came from, since there were no dead animals nearby or compost. Perhaps an insectivorous bird dropped it, or maybe this particular species likes chicken manure (there was a chicken tractor nearby vroom vroom). Putting this next part below the cut because it's a little gross. Proceed with caution:

This carrion beetle child seemed somewhat hungry, as it was nibbling at some dead skin around my finger nail. It tickled a bit and reminded me of the shrimp they sometimes have at aquariums that will nibble at your fingers. Yes that's a thing.
