Unveiling the ocean's secrets: The sea sheep, an intriguing creature beneath the waves
Seas and oceans form the largest unexplored area on Earth, giving scientists ample opportunities for discovery, work, and innovation. It's key to remember that exploring the waters of our globe is necessary for understanding oceanic systems and their processes better, vital to human survival. At times, not just experts but even ordinary divers encounter rare and unique species of underwater fauna and flora. One such intriguing creature reminds people of Shaun the Sheep (a character from animation) or a Pokemon! What creature is this, and does it pose any threat to us?
Introduction to the sea sheep
This unusual and captivating sea creature has been dubbed as the sea sheep or the leaf sheep. Despite its deceptive name, it doesn't resemble a large furry mammal in any way. Its full name is Costasiella kuroshimae. It's a small sea slug, often just under half a centimetre. Sea sheep are invertebrates characterised by their creamy, gelatinous bodies. Their black eyes and dark tentacles are their most distinguishing features, reminiscent...of a sheep’s ears! Thanks to these tentacles, Costasiella kuroshimae can locate food and avoid various dangers.
A glimpse into the habitat of this unique marine creature
The sea slug, Costasiella kuroshimae, is common off the coasts of Japan, the Philippines, North Australia, and Indonesia. These creatures have only been known to the scientific world for a few decades. Experts are still in the process of uncovering information about this sea slug, including their lifespan. However, one thing we know for sure is these creatures are not dangerous to humans. It's worth emphasising that Costasiella kuroshimae was first discovered in waters near the Japanese Islands in 1993.
Most people who have seen these creatures in person are often surprised by their miniature size. Along with this, these invertebrates have body markings with distinctive green patches that look like leaves. But in actuality, these are branched digestive glands. Interestingly, most sea sheep are green, though as per researchers, these creatures might also come in a range of other colours.
