This ocean creature is known as a comb jellyfish. I cannot think of a more inappropriate name. It is not a fish, it does not seem to resemble jelly, and it certainly does not resemble a comb.
Ever wondered what a hairy squat lobster looks like?
It is one of the rarest animals on the planet, the coelacanth. There are no live specimens in captivity, but there are a few dead ones, like the one above in an aquarium in Numazu, Japan.
And here is another view.
The puffer fish (or blowfish, or globefish) is probably the second most poisonous vertebrate (the most poisonous being a golden frog).
In Japan, Korea and China it is prepared by specially licensed chefs and is often eaten raw. I once ate it. The flavour was good, but no better than many other fish.
Last year this eel was found for the first time in an ocean cave in Palau.
It is so different from common eels that it is not only a new species, it is a new genus too, Protoanguilla palau is its full name, and it has been around for millions of years.
It is thought that there are thousands and thousands of animals still waiting to be discovered, especially in the oceans and underground.
This is a cousin of the seahorse, but is much rarer. The Weedy Seadragon can be found in the oceans near southern Australia.
In the Gulf of Mexico can be found one of the most unusual fish, the pancake batfish.
