  1. Hello, everyone. I am both happy and a little sad to present my final weekly update. Unfortunately, I’ve been busy with real life matters that are demanding more and more of my attention, and since my workload won’t be decreasing anytime soon, I’ve decided to discontinue this project to focus on other things. I didn’t intend for this to end so soon, but life happens. Since this is my last update, I thought it would be fitting to feature my favorite aquarium creatures that never got their own post, complete with some background info for each one. This is a lion’s mane nudibranch. They’re fairly common in kelp forests, and my boss often finds them during his shrimp collections. They use their hoods to snare prey, and the ones at SMPA are fed with brine shrimp and the occasional fish powder. That stuff you see inside its body is its last meal. This is our ocean whitefish, a resident of the “Under the Pier” exhibit. Whitefish are usually a creamy-white color, but this one is an unusual and ironic shade of black. It’s the most dominant fish in the tank and will often attack the algae scrubs when we try to clean the glass. (Also, the fish behind it is a kelp seabass) Another abnormally colored animal is our red swamp crawfish. While most of our creatures are saltwater natives, the red swamp crawfish is neither saltwater nor native. As an invasive species, it is used as a bad example for our field trip presentations, but who could hate that rare shade of blue? Here’s our scorpionfish. It has stingers all over its body, and its venom is said to be like that of a rattlesnake’s. If you go fishing in California waters, you better hope you don’t catch one of these. The only safe way to get rid of it would be to cut the hook. They do sell protective gloves that are supposed to be stinger proof, but even these sometimes fail. And here’s our stargazer, who is located in the back room. It used to be on display, but was removed because the guests apparently found it boring (???). Nowadays it spends its time gazing at the stars, wondering where the roof went. And now we’re getting to my favorite creature in the aquarium: the keyhole limpet! There are a bunch of these in the touch tanks, and the above photo is one of the very first I took as an intern. I love gastropods in general, but there’s just something about the keyhole limpets in particular. Just like most of our sea snails, they feed on kelp, and their backside is usually covered by a slimy black mantle. However, the limpet that lives in our “Rocky Reef” exhibit always has its mantle fully retracted for whatever reason. Here’s a photo of it: Also, the “keyhole” is used to expel waste. Good luck getting that image out of your head. Lastly, I would like to present our newest addition: This is a bell jellyfish, and several of them are now sharing a tank with the planktonic jellies I showed off last week. They’re known to scientists as “Polyorchis,” which means, “many testicles”. No, that’s not a joke. I think the name refers to the eyes lining their rim. Just like their snowflake-shaped tank mates, they’re happy to feed on brine shrimp. There you have it, folks. I wish I could’ve kept this thread going a bit longer, but the good news is that I at least managed to share my favorite aquarium facts. That said, I appreciate everyone who took the time to read these posts and learn about my experiences. I’ll still be reading replies for another day or two, but after that, I’m off to bigger and better things. Cheers! -Kamran
  2. This week's update is about our newest exhibit. It features a species of planktonic jellyfish. Periodically, my boss goes to collect the wild shrimp (Mysidae) to feed our Pacific seahorses. We kept them in the tank (pictured above) until it's feeding time, but sometimes, we'll get animals. Our accidental catches range from amphipods to pipefish larva, but the most common example is Vallentinia adherens. Their numbers got really high after a while ... ... So in response, my boss decided to give them their own tank. We feed them brine shrimp, and they no longer get in our way when he feeds the seahorses. At first my coworkers and I thought these were jellyfish larvae, and visitors tend to make the same assumption. But they're definitely adults, and now they've gone from an accidental catch to a featured species. Hopefully the baby pipefish will get a tank when they're older. -Kamran
  3. For this week's update, I've decided to focus on our decorator since its appearance has been changing. Decorator crabs like to cover themselves with plants for camouflage. Our decorator crab does this too, and over the past month, it's been adding things to its shell. This is how it looked two weeks ago. It had molted recently, so its shell was uncovered. The following week, it put on some kelp. When my coworker saw this, she added some red algae to the tank, and a week later ... ... it put the algae on its legs. We have other decorator crabs too, like juveniles and another adult. Here is a picture of its disguise: Also, here's an old molt that we preserved. The crab was much smaller back then ... I hope you enjoyed this update. Next week, I'll discuss one of our newer exhibits. -Kamran

  5. (Thank you for the translations!) Hello again, everyone. One of our swell sharks recently emerged from its embryo, so for this week’s update, I thought I’d provide a summary of how the aquarium handles its shark offspring. Currently, we have two kinds of sharks on display: swell sharks (first photo) and horn sharks (second photo). Although both our sharks reproduce, the swell sharks do it more often and will be the focus of this post. These are what swell shark embryos look like. These three are in a public tank, and we have many more in the back room. When a pup emerges from its embryo, it’s immediately moved to the quarantine tank seen in this photo. There are a lot of them, and only three horn shark embryos in comparison. Several things can happen to the pups after they are born. Sometimes, they’re moved to the public exhibit (pictured above), which is what happened to the newest pup. Other times they’re donated to other aquariums, and still other times they’re kept until they’re large enough for the main shark tank. It depends on how much room there is. An adult swell shark spat water at me once. It was unpleasant. -Kamran
  6. The time has come for my first official update. The Santa Monica Pier Aquarium is nestled beneath the very front of the pier, with a nice big aquarium banner for good measure. Every creature on display is native to Santa Monica Bay, with a few exceptions (ex: El Nino caused some Pacific seahorses to appear in our waters, which were then collected and given their own exhibit). Obviously, the goal is to give visitors a sense of what is right the bottom of the bay, and most of our main exhibits are modeled after a specific ecosystem. Attached to this post a few photos showing the aquarium's position in relation to the pier, the entrance, and some of our exhibits. All of these photos are mine, except for the aerial shot. If you have any questions, please do not hesitate to ask! -Kamran
  7. Help translate? (Помогите перевести?) Hello, everyone. My name is Kamran, and I am a helper here at Santa Monica Filtration. I am also an aquarist intern at the Santa Monica Pier Public Aquarium: https://healthebay.org/aquarium/ I’ll be giving periodic updates regarding various going-ons at the aquarium, and if you have any requests for things you want me to find out about our creatures, feel free to share. I hope you all enjoy!

  19. вынос питательных веществ Что все водоросли (и циано тоже) нужно, чтобы выжить ? Питательные вещества . Каковы питательные вещества? Аммиак / аммоний , нитриты, нитраты, фосфаты и мочевина являются основные из них . Какие из них вызывают большую часть водорослей в аквариуме ? Эти же самые . Почему вы не можете просто удалить эти питательные вещества и устранить все водоросли в аквариуме ? Потому что эти питательные вещества являются результатом животных вы держите . Так как же ваши животные " сделать " эти питательные вещества ? Ну большая часть питательных веществ происходят из мочи (мочевина) . Пи является очень высоким в мочевины и аммиака , а этолюбимая еда водорослей и некоторых бактерий . Вот почему ваш стакан всегда будет нуждаться в чистке ; потому что моча попадает в стакан , прежде чем что-либо еще, и водоросли на стекле сразу потреблять аммиака и карбамида (используя фотосинтез ) и расти больше. В океане и озерах , фитопланктон потребляет аммиака и карбамида в открытой воде , и водоросли потребляют его в мелководных районах , но в баке у вас нет достаточно места или объем воды для этого, и ваши другие фильтры или животных часто приводит к удалению или убить фитопланктон или водоросли в любом случае. Таким образом, питательные вещества остаться в вашем аквариуме . Тогда аммиака / аммония парад ваши камни , и перифитон на них потребляет больше аммиака и карбамида . Перифитон есть как водоросли и животные , и является причиной ваши камни меняют цвет после нескольких недель . Тогда аммиака идет внутри скалы , или бьет тебя в песок , и бактерии там преобразовать его в нитритов и нитратов . Однако , питательные вещества по-прежнему в вашем аквариуме . Также давайте не забывать, фосфат , которая поступает из твердых органических частиц пищи . Когда эти частицы поедаются микробов и убирать экипаж , органический фосфор в них превращается в фосфат. Однако , питательные вещества по-прежнему в вашем аквариуме . Поэтому, когда у вас есть водоросли "проблемы" , вы просто не экспортировали достаточное количество питательных веществ по сравнению с тем, сколько вы были кормления ( к сведению : . Живые камни могут поглощать фосфат на срок до одного года , что делает его показаться никогда не было проблемой Тогда , существует проблема ) . Так что просто увеличить экспорт питательных . Кроме того, можно уменьшить подачу , и это имеет такой же эффект , но это , конечно, не весело, когда вы хотите , чтобы накормить своих животных ------------------------------------------- ENGLISH --------------------------------- Nutrient Export What do all algae (and cyano too) need to survive? Nutrients. What are nutrients? Ammonia/ammonium, nitrite, nitrate, phosphate and urea are the major ones. Which ones cause most of the algae in your tank? These same ones. Why can't you just remove these nutrients and eliminate all the algae in your tank? Because these nutrients are the result of the animals you keep. So how do your animals "make" these nutrients? Well a large part the nutrients come from pee (urea). Pee is very high in urea and ammonia, and these are a favorite food of algae and some bacteria. This is why your glass will always need cleaning; because the pee hits the glass before anything else, and algae on the glass consume the ammonia and urea immediately (using photosynthesis) and grow more. In the ocean and lakes, phytoplankton consume the ammonia and urea in open water, and seaweed consume it in shallow areas, but in a tank you don't have enough space or water volume for this, and, your other filters or animals often remove or kill the phytoplankton or seaweed anyway. So, the nutrients stay in your tank. Then the ammonia/ammonium hits your rocks, and the periphyton on them consumes more ammonia and urea. Periphyton is both algae and animals, and is the reason your rocks change color after a few weeks. Then the ammonia goes inside the rock, or hits your sand, and bacteria there convert it into nitrite and nitrate. However, the nutrients are still in your tank. Also let's not forget phosphate, which comes from solid organic food particles. When these particles are eaten by microbes and clean up crew, the organic phosphorus in them is converted into phosphate. However, the nutrients are still in your tank. So whenever you have algae "problems", you simply have not exported enough nutrients compared to how much you have been feeding (note: live rock can absorb phosphate for up to a year, making it seem like there was never a problem. Then, there is a problem). So just increase your nutrient exports. You could also reduce feeding, and this has the same effect, but it's certainly not fun when you want to feed your animals
