Sea Hares

After seeing the nudibranch and flatworm on my previous dives, I was not surprised when seeing for the first time of the following marine species in Ambon Bay (Indonesia):

A new nudibranch species from Ambon (Indonesia)?
My thought at the first time seeing it, it was another species of nudibranch with eyes. Nice, finally there was a nudibranch species that has a face. But this gal was not a nudibranch. I was wrong.

Nudibranch Flabellina iodonea. A face without “eyes”.
It is called as Sea Hares. Yep, in another word: “Sea Bunnies”. These animals have been called ‘Sea Hares’ since classical times because of their resemblance – at least in European species – to a sitting hare (source). Do they look like a sitting hare? – The picture of a sitting hare is available in [here].

It is a sea hare, not a nudibranch
One thing that I adore is their tiny eyes. Their eyes just like Cleopatra’s eyes. It appears their eyes can only tell light from dark, so instead, they use a pair of rhinophores atop their head and a pair of oral tentacles either side of their mouth (source).

Pretty eyes even without mascara 😉
They don’t jump like the bunnies or hares. The sea hares squirt out purple inks. This behavior reminds us of the octopus, but unlike the octopus who squirt and disappear, the sea hares squirt and stay. Why they squirt and stay is still a mystery to solve.

Their purple inks are toxic for other animals
I have seen the sea hares during my dive trips in Cape Verde and Indonesia. Basically, the sea hares can be found in many parts of the world. They often being swept away to the beach as well, thus, beware of the sea hares as their inks are toxic and as reported in Australia, they could be deadly to dogs.

They look really pretty but silly question – which one are their eyes? I guess I’m not that familiar with these sea creatures to figure it out myself…oh no..Haha
lol I do have a similar question too. The sea hare at least has that dot thingies that looked like eyes. But the nudibranch just use the antenna on top of their head. A bizarre animal 😀
Ahh I see, that’s pretty unique to see! You get to learn something new after all…hahaha 🙂
Very cool, this is the first time I’ve ever seen or heard of a “sea hare” ~ and it looks beautiful. The variety of animals underneath the water never ceases to amaze. Wishing you well.
It’s kinda weird creature, I guess. I hadn’t known it either until seeing them during the dive 😀 Thank you so much, Randall!
seperti keong kak tanpa cangkang, kalau lihat aslinya pasti lucu
Iya bener banget, Winny. Makasih yaaa
Very cool and I see those Cleo eyes 😉
That’s quite remarkable eyes to me – not easy eyes make up 😀
Such beautiful captures of the colourful and strange creatures of the sea.
Thank you so much, Otto!
I had never heard of Sea Hares…what incredible pictures Indah!!
Thank you, Kirt! I am happy to introduce this unique species 🙂
Love the name sea hares! Definately not as fluffy as my rabbit but fascinating creatures. I’ve never heard of them before. Thanks for the introduction 😊
Hahaha, I wish they can jump like the rabbit! 🙂
That would be pretty epic and probably completely confuse predators!!!!
LOL that’s true!!
Your underwater photography is magnificent as always Indah. I’ve never seen a Sea Hare before. So cool!
Thank you so much, Lisa!
