Introducing the SOS Marine Science Scholars Program in Tanzania — and our first Scholar, Abbas Mbarouk!

Abbas holds a B.Sc. in Marine Science from the University of Dar es Salaam’s Institute of Marine Science and brings hands-on experience in sustainable marine tourism — including dolphin and coral reef education — from his time with African Impact. Now, as part of this new initiative, he’s diving deeper (literally 🤿) into marine science, coral reef restoration, and conservation alongside and the team at in Jambiani, Zanzibar — including learning to dive as part of the program!

Over the next 12 weeks, Abbas will be embedded in our coral larval propagation project, developing the field skills, scientific training, and professional experience to help build a stronger future for Tanzania’s reefs — and for Tanzanian marine science itself. And he’ll be bringing you along for the journey! Follow along as Abbas shares his experience from the water over the coming weeks. We couldn’t be more excited to have him on the team!

Tunatambulisha Programu ya Wasomi wa Sayansi ya Bahari ya SOS — na Msomi wetu wa kwanza, Abbas Mbarouk!

Abbas ana Shahada ya Sayansi ya Bahari kutoka Chuo Kikuu cha Dar es Salaam, Taasisi ya Sayansi ya Bahari, na ana uzoefu wa vitendo katika utalii endelevu wa baharini — ikiwemo elimu kuhusu pomboo na miamba ya matumbawe — kutoka wakati wake na African Impact. Sasa, k**a sehemu ya mpango huu mpya, anazama zaidi (kwa kweli 🤿) katika urejesho na uhifadhi wa miamba ya matumbawe, akifanya kazi pamoja na timu ya marinecultures.org huko Jambiani, Zanzibar — ikiwemo kujifunza kupiga mbizi k**a sehemu ya programu!

Katika wiki 12 zijazo, Abbas atakuwa amezama ndani ya mradi wetu wa uenezaji wa viluwiluwi vya matumbawe, akijenga ujuzi wa uwanjani, mafunzo ya kisayansi, na uzoefu wa kitaalamu ili kusaidia kujenga mustakabali imara kwa miamba ya Tanzania — na kwa sayansi ya bahari ya Kitanzania. Naye atakuwa akileta safari yake kwenu!

No those corals aren’t smoking, they are releasing clouds of s***m as part of their annual reproductive effort. This population of _Porites rus_ may release their gametes (eggs and s***m) each month 5-6 days after the full moon, for the next few months. As part of our project in Zanzibar with to lay the foundation for coral larval propagation we are documenting coral spawning patterns like this. For the marinecultures.org house reef this is the first recorded observation of this species spawning and one of few spawning records in the entire region!

Dr Ashlee Lillis, founder and director of SOS, recently visited the incredible Aavishkaar Center for Math, Science, Art, and Technology in Northern India . Along with research associate we were able to share a bit of our work in the oceans with the center’s enthusiastic educators and education researchers. Another reminder that from the mountains to the sea, we are all connected 🌍

We are deeply inspired by Aavishkaar’s efforts to revolutionize education in maths and sciences.

Part 2/2 Pemba Project August Recap!

Led by our intern Samantha, Sound Ocean Science hosted a hands-on training with the team to teach the ins and outs of using specially-made coral camera traps, designed to capture coral spawning activity in the nighttime. Together, we programmed and deployed two Coral Spawning Cameras to monitor selected coral assemblages in the Pemba Channel.

These cameras are set to take bursts of photos every 5 minutes throughout the night, when corals are known to spawn but we cannot be there in person. Next steps in Pemba will include refining the deployment and camera settings to take better quality images that will enable us to find the elusive coral spawning events!

Stay tuned for some spawning paparazzi 🪸📸

For this edition of Journal Club, we highlight work from 2024 by Dantzker et al. This study developed a high-tech gizmo to connect fish sounds to species in the hustle and bustle of coral reefs in Curacoa.

This is important because reefs are full of sounds, but until now, we couldn’t tell who was making the. This limits our ability to monitor biodiversity, detect invasive species, and track behaviors. Using this method, the team identified 40 species, many for the first time! And this is only the start.

Sound Ocean Science is also working to add fish sound IDs to global libraries, helping scientists monitor reef ecosystems and build AI tools to “listen” to the oceans.

Stay tuned for more reef sound discoveries!

We have been seeing lots of cool, colourful, squishy creatures on our dives lately, which made us wonder - do people know the difference between a sea slug, nudibranch, sea hare or marine flatworm?" 🤔 If the answer is no, you're not alone! These ocean critters are often confused because they share similar features, but let’s break down the differences so you can spot them like a pro! 🌟

1️⃣ **Sea Slugs**: This is a general term for soft-bodied, marine gastropods (shell-less snails or slug-like critters of the sea). Not all sea slugs are nudibranchs, but they’re often called this! Nudibranchs are all a type of sea slug but there are a bunch of other groups in this classification as well. They come in a variety of shapes and sizes and can be pretty much anything from drab to dazzling, and this category usually includes the larger sea hares. 🐌

2️⃣ **Nudibranchs**: A *special* type of sea slug, these beauties are known for their vibrant colors and intricate patterns and usually range from a few mms to a few cms, depending on species. Think of them as the *fashionistas* of the sea. 🌈 They have gills that protrude from their backs, known as *rhinophores*. 🐚

3️⃣ **Marine Flatworms (Platyhelminthes)**: Flat, often colourful or striped, and sometimes having similar patterns of nudibranchs or sea slugs, marine flatworms are easily and often mistaken for sea slugs by the untrained eye. But flatworms are *not* gastropods, they're more closely related to other invertebrates like planarians. They have smooth bodies and also usually lack the distinctive gills and “frills” seen in nudibranchs.

So next time you spot one of these ocean gems, you'll know what makes them different! 🌊🐚 Can you differentiate between the nudibranchs, flatworms, and other shell-less gastropods in our photos? Let us know in the comments if you can't tell who is who! 👇👇

What a year! In 2024 Sound Ocean Science worked globally to uncover the secrets of marine life like our favourite noisemakers - the snapping shrimp 🥰

Today we wish all our coral, shrimp, fish, and human friends a Snappy New Year! 🥳

Keep following for updates on our favourite discoveries of 2024 and what's on the go in 2025. We have a feeling it is going to be shrimply the best!

Happy Halloween ocean lovers!

We have been spending many nights underwater lately observing the spooky critters that appear after dark. Many of our favorites are animals masquerading as other things!

Enjoy some of our favourite creatures in "costume".
