Unusual creatures we share our world with
The Leafy Sea Dragon
A marine fish in the family Syngnathida, which also includes seahorses. It is the only member of the genus Phycodurus. It is found along the southern and western coasts of Australia
Those that live in the deep waters are generally more dark brown to burgundy, while those living in the shallow water are more yellow to greenish.
The Pygmy Seahorse is known to occur only on gorgonian corals of the genus Muricella, and they have evolved to resemble the coral.
The Sea Horse has kept itself so well camouflaged that it was not discovered until a specimen of coral was taken by scientist and the little Sea Horse was finally spotted
during an examination of the coral!
The Ocean Sun Fish
Injuries from sunfish are rare, although there is a slight danger from large sunfish leaping out of the water onto boats.
Adult sunfish are vulnerable to only a few natural predators.
Sea Lions, Orca & Sharks will consume them.
Among humans, sunfish are considered a delicacy in some parts of the world, including Japan. The sale of their flesh is banned in the European Union.
In the course of its evolution, the caudal fin (tail) of the sunfish disappeared, to be replaced by a lumpy pseudo-tail, the clavus. The ocean sunfish resembles a fish head with a tail.
It’s a Sea Slug!
Spanish shawls are hermaphtodites, which means they have both male and female sex organs. However, self-fertilization very rarely occurs.
When in harm by other predators, they can gracefully move away by flexing their body strongly and pushing off.
Another type of Sea Slug
They can always be distinguished by the bright orange stripe down the midline of the dorsum. A blue to white line occurs on the dorsal surface of the oral tentacles. At the the rhinophores this line splits in two, with one line following the edge of the foot to the tail, the other flanking the orange midline stripe.
They will eat small crustaceans, tiny clams or dead animals of any sort. They will even eat other.
When mating most are often found in southern California in winter, but are found year around in the Puget Sound (Washington)
Many studies have been carried out on Hermissenda, but the main area of focus is the eye. It has five cells, each about 75 um in diameter, which are large enough to receive a recording electrode. Within the cells it is suspected of containing symbiotic fungi. Hermissenda is an aggressive creature. When two individuals encounter fights will break out, which involves lunging and biting. Encounters most likely to induce a fight are those of mutual head on contact. The individual whose head is closest to the others tail or side will usually get the first bite in, this also means that they usually come out the winner.
