The vast and beautiful open ocean of the tropics is the largest ecosystem on the planet...
These jellyfish usually have four arms, but are most recogniseable by the long long wispy tentacles trailing from the bell. The edges of the domed bell are scalloped.
Aurelia aurita, 'Moon Jellyfish'.
These sea-Jellies have eight 'fluffy' divided arms hanging from the bell, rather than the thin wispy tentacles seen on other jelly fish.
Mastigias papua, 'Spotted Jellyfish'.
Cassiopeia ornata, 'Upside-down Jellyfish'.
Nebrius ferrugineus, 'Tawny Nurse Shark'.
This family only contains one living species...
Rhincodon typus, 'Whale Shark'. The biggest fish on the planet.
This group contains various families of mostly unusually shaped fish such as Boxfish, Pufferfish and Sunfish.
There are three species of Sunfish. They look like giant heads with tails, and often bask sideways at the surface of the ocean. They are the heaviest bony fish in the world. The most widespread is the Mola Mola 'Sunfish' found in tropical and temperate oceans around the world. Mola alexandrini, 'Southern Ocean Sunfish', 'Bump-head Sunfish' is found around south-west Pacific.
The following species of flying fish I have given some common names based on the survey book 'Flying Fish'. However, taxonomy on flying fish is unresolved and there are no field guides as such, so take all of these names with a BUCKET LOAD OF SEA SALT - they are just guesses!
Cheilopogon sp.'Yellowband Flying Fish'.
? 'Pink-winged Apache'
? 'Black-eyed Pinkwing'
? 'Freckled Pinkwing'
? 'Rosy-veined Clear-wing'
? 'Solomon Cerulean Flying Fish'.
? 'Pink-tailed Clearwing'
? 'Blue Bandwing'
Chelonia mydas, 'Green Turtle'. Widespread throughout the world's tropical and warm temperate seas.
Onychoprion anaethetus, 'Bridled Tern'.
Phaethon lepturus, 'White-tailed Tropicbird'.
'White-tailed Tropicbird' in the surface of the water.
Fregata magnificens, 'Magnificent Frigatebird'. Found around South and Central American ocean waters.
Stenella longirostris, 'Spinner Dolphin'. This species probably includes many species; as the very least there are many distinct forms around the world. In the middle of the Pacific Ocean, far away from land, I have seen very tiny forms of Spinner Dolphins.
The 'Bottlenose Dophin' is now usually considered to be three or even four different species. Two occur across larger areas of the tropics, with the larger 'Common Bottlenose' Tursiops truncatus, being more widespread and also found in deeper more open water. The closer they examine these two species, the less closely related they seem to be.
Tursiops aduncus, 'Inshore (Indo-Pacific) Bottlenose Dolphin'. Usually found in coastal waters, around the Indo-Pacific oceans.
Megaptera novaeangliae, 'Humpback Whale'.
