Ever heard that saying that we know more about space than the ocean?

Well, it probably isn't quite true, but there is certainly a lot we don't know.

Last year, we made a bunch of new discoveries - truly amazing life hidden deep - and not so deep - beneath the waves. Here are just a few of them.

🐟 The Lady Elliot shrimp goby.

This 5-centimetre fish was spotted hanging out on a shallow reef at Lady Elliot Island, which is part of the Great Barrier Reef. The last time a new-to-science species was discovered in the Great Barrier Reef was in 2019.

🐟 The Vanuatu scorpionfish

Yes, a relative of our flame-coloured friend just above! The Vanuatu scorpionfish became a new-to-science species thanks to work done by researchers on four specimens collected from Malekula Island back in 1994 and kept in storage until recently.

🐌 The margarita snail

Found on a coral reef in the Florida Keys, the margarita snail gets its name from its brilliant bright yellow. Unlike the snails you find in your garden, these snails tend to live in the same spot for pretty much all their lives.

🪸 Pocillopora tuahiniensis

This new stony coral species was found in French Polynesia. Identifying corals is pretty tricky because they can look very similar. Advancements in genomics are helping us separate them out.

🧽 Megaciella sanctuarium

Back over in the USA, a new species of sponge has been discovered off the coast of California. The species is named after the Monterey Bay National Marine Sanctuary, where the sponge was spotted back in 2021. Actually, the research voyage that found this new species also led to the discovery of 11 other new-to-science sponges!
