Nudibranchs are distantly related to sea slugs. Nubibranchs are primarily sighted at reefs and the deep ocean. These beauties are renowned for their often striking colors and unusual bodily forms.
And yes, your suspicion is correct - the word "nudibranch" comes from the Latin nudus, i.e. naked.
They are hermaphroditic, which means that they have a set of both male and female reproductive organs, both produce eggs, but are unable to fertilize, laying their eggs within a gelatinous spiral.
Their flesh is poisonous and unpalatable.
Lion’s Mane Jellyfish
This regal looking creature, also known as ‘hair jelly’, is identified as the biggest known jellyfish. It’s typically found in the waters of the Arctic, northern Atlantic, and northern Pacific Oceans, Australia and New Zealand.
The lion’s mane uses its stinging tentacles to capture prey; however, sea anemones can seize their tentacles, which become tangled and risk being torn apart
With an uncanny resemblance to bulldogs, the stargazer fish should be on your bucket list if you’re not allowed to keep a canine.
Smooth trunkfish are found in coral reefs
Word of advice: don’t piss them off. When provoked, toxins are released from their flesh which can kill assailing fish and themselves.
These creatures are believed to have originated from the very pits of hell itself.
Peacock Mantis Shrimp
This paradisiacal creature is magnificent. This shrimp, which looks like it’s been conjured by Alice’s imagination, feeds on its prey by smashing it open until it can access its tissue.
Flamingo Tongue Snail
A class of tiny but vibrantly colored sea snail.
Sea squirts are sessile animals – typically, they stay tightly attached to substratum, such as rocks and shells but are often found swimming freely as well. Essentially, they enjoy physical and behavioral characteristics of both seabed-dwelling and free-swimming organisms.
They are not limited to certain geographical locations – often sighted all over the world in saline waters.
This distinctive animal is believed to embody a "transitional organism" which also enjoys both seabed dwelling and swimming freely tendencies.
Maybe there’s Santa under the sea too?
A very pretty looking mollusk, the lined chiton flaunts colorful lines on its valves with white or yellow spots or bands on its girdle. It’s breathtaking hue also serves practical purpose: concealing it from predators as it feeds on coralline algae.
The parrotfish bears an uncanny resemblance to another favorite domestic pet. It is able to alter its shape, color, and even gender during its lifetime.
It may look formidable, but the Atlantic wolffish is not known to be particularly vicious. Wolffish possess an innate ‘antifreeze’ system which enables blood movement when they feel particularly cold.
No – this bizarre creature is not plants floating in the sea. This here is a marine fish whose long leaf-like protrusions serve as camouflage.
Flower Hat Jelly
This exquisite jelly is bea-u-tiful.
Don’t let their ethereal looks disarm you: the flower hat jelly can deliver an excruciating sting. Found off Brazil, Argentina, and southern Japan.
