Featured observation: Weedy pygmy seahorse by kati-romblon

Our new featured observation comes to us from kati-romblon, who snapped this great pic of the weedy pygmy seahorse (Hippocampus pontohi) in Romblon, Phillipines. kati-romblon is looking like a rather proliferate user, having posted 12 observations of 5 species already!

The weedy pygmy seahorse is a species that inhabits algae and soft corals among the Indo-Pacific islands. Being one of the smallest species, it grows only to a maximum of 1.4 centimetres and so is very tough to spot in the water.

As a result of its small stature and cryptic nature, the species was only discovered in 2008. Scientists do not currently have enough information to know how well the species is doing, and so it is listed as ‘Data Deficient’ on the IUCN Red List of Threatened Species. Observations like these will help us to gain a more comprehensive understanding of the weedy pygmy seahorse, thereby enabling us to protect it and its ocean home.

Thanks for the observation kati-romblon!

Featured observation: Giraffe seahorse

Every few weeks we're going to be highlighting a new and noteworthy seahorse observation.

This week’s featured observation comes to us from hdarrin, who managed to snag a photo of a giraffe seahorse (Hippocampus camelopardalis) in Inhambane Bay, Mozambique.

H. camelopardalis makes its home along the southeast coast of Africa from Tanzania to western South Africa. It lives in seagrass, algal beds, and on shallow reefs. The species is traded heavily in Tanzania as a curio, but is listed as Data Deficient on the IUCN Red List of Threatened Species, as very little is known about it.

This and other future observations of the Giraffe Seahorse on iSeahorse will be used by scientists and conservationsists to get a better idea about its biology and geographic distribution, and will hopefully help to inform decisions about the management of its ocean habitat.

Thanks for the observation hdarrin!

Featured observation: Knobby seahorse

iSeahorse's first featured observation comes from tamiw, who spotted this short-head or knobby seahorse (Hippocampus breviceps) near Melbourne, Australia.

H. breviceps is endemic to Australia and makes its home on sponge reef, sargassum, and rocky reef in deeper water. Its maximum recorded adult height is 10 cm and the males have tails proportionally longer than the females.

The species is currently listed as Data Deficient on the IUCN Red List of Threatened Species, meaning we do not yet have enough information about H. breviceps to determine its conservation status.

Thanks, tamiw, for your observation!

The results so far...

It's been just about eight weeks since the official launch of iSeahorse. Collectively, as citizen scientists, we've logged 173 seahorse observations in just about every corner of the world, from Africa to Australia, South America to Asia, and beyond.

Most promisingly, there have been observations of 23 different seahorse species, including some rarely seen ones such as the West African seahorse (Hippocampus algiricus), Reunion seahorse (H. borboniensis), Severnsi’s pygmy seahorse (H. severnsi), short-head seahorse (H. breviceps), and the sea pony (H. fuscus).

Your data and stunning photos will prove very useful as the iSeahorse and Project Seahorse teams continue their work on seahorse conservation.

Thanks to everyone who has joined iSeahorse so far, and please be sure to encourage your friends and colleagues to join as well! Special congratulations go out to iSeahorse user davidr, who leads all contributors with 16 observations and 5 different species sighted. Great work!

Observation map issue

We're currently experiencing minor technical issues with our observation map. For most of today, you may find that the map does load properly. We're working on a fix and should have everything running smoothly very soon.

In the meantime, you can still upload your sightings. They will be saved to the database and viewable on the map when it is back online. Thanks for your patience.

UPDATE: The map issue is fixed!

Off to a roaring start

Just a quick note of thanks to everyone who has joined iSeahorse and contributed observations so far. The iSeahorse team is thrilled with the amazing response so far and we'll be doing our best to help with all the species IDs for your sightings.

Don't forget that you can do the same: You can help identify species by clicking the ID button at the bottom of any individual observation. We have two different ID guides that will help with identification.

Welcome to the new Getting started

We're pleased to launch the brand-new iSeahorse website today. What is iSeahorse? Simply put, it's a tool for seahorse science and conservation.Whether you’re a diver, or a fisher, or a scientist, or a seahorse enthusiast, we need your help!

iSeahorse harnesses the power of ‘citizen scientists’ — anyone, anywhere in the world who sees a seahorse in the wild — to improve our understanding of seahorses and protect them from overfishing and other threats.

You can upload your photos and observations. You can help identify seahorse species. You can advocate for their protection in your ocean neighbourhood.

To get started, create an iSeahorse account today.

Scientists from Project Seahorse and seahorse experts around the world will use your vital information to better understand seahorse behaviour, species ranges, and the threats seahorses face. We will use this knowledge to improve seahorse conservation across the globe.

For iSeahorse users involved during the beta-testing phase of the website, you'll notice that the our seahorse observation tools and database are now powered by iNaturalist, one of the most sophisticated and powerful citizen science tools on the web. Within the next few days, you will receive an email explaining the changes and what this means for your existing observations data. Drop us a line if you have any questions or concerns in the meantime:

Thanks for visiting! We hope to see you around the site.

Changes at iSeahorse

Just a heads up to current iSeahorse members on iNaturalist: Next week we'll be launching, our standalone citizen science site with integration. This means that you'll be able to submit your observations via either iSeahorse or iNaturalist and they will be added to the iNaturalist database and maps. We will launch a dedicated iSeahorse app for iPhone in the coming weeks as well.

More info to follow very soon.
