Temperate Ocean

The temperate oceans of New Zealand and southern Australia...

Ecklonia radiata, 'Common/Spiny Kelp'.  Can form dense underwater forests. Found from shallow waters down to 25 metres. Widespread in temperate waters of southern hemisphere.

Kingdom Plantae

Order Asimatales

Family Poisidoniaceae

Posidonia sp. 'Strapweed'. A group of seagrass with a disjunct distribution; they are found in the Mediterranean and in southern Australian waters.

Kingdom Animalia

Phylum Cnidaria: Corals and Sea Jellies

Antipathella (previously Antipathes) fiordensis, 'Black Coral'.

Phylum Annelida

Class Polychaeta

Protula sp. 'Marine Polychaete Worm' 

Phylum Echinodermata: 
'Sea Stars', 'Sea Cucumbers' etc

Family Asteriidae

Coscinasterias calamaria, 'Eleven-armed Sea-star'. Found along southern Australia and New Zealand shores. 

Fish

Family Serrandiae

Caesioperca lepidoptera, 'Butterfly/Red Perch'. Found in New Zealand and southern Australian waters.

Family Kyphosidae: 'Sea Chubs', 'Drummers'

Kyphosus cornelii, 'Western Buffalo Bream'.

Family Pomacentridae: Damselfish

Pomacentrus milleri, 'Miller's Damselfish'.. Adults uniformly dark dull, with blueish tinge, darker edged scales and lighter blue on edge of fins. Extends into tropical areas of eastern Indian Ocean, where it is often brighter in colour.

Family Labridae: Wrasses

Pseudolabrus miles, 'Scarlet Wrasse'. Endemic to New Zealand.

Notolabrus fucicola, 'Blue Wrasse'. Found in temperate eastern Australian and New Zealand waters; in the latter region it is the largest wrasse.

Coris auricularis, 'Western King Wrasse', juvenile. Found along west Australian coast. When at juvenile stage, often works as a cleaner fish.

Family Monacanthidae

 Meuschenia scaber, 'Smooth/Velvet Leatherjacket'.

Class Reptilia

Chelonia mydas, 'Green Turtle'. Even though they do not grow as large as Leatherback or Loggerhead turtles, the individuals in cooler waters can be large and heavy, much more so than their tropical equivalents. The Green is the most widespread and commonly seen of the marine turtles, and although they are mostly tropical, they can turn up in cooler waters all around Australia. 

Class Aves: Birds

Order Charadriiformes

Family Laridae: Terns & Gulls

Thalasseus bergii, 'Crested Tern'.

Family Spheniscidae: Penguins

Eudyptes pachyrhynchus, 'Fiordland (Crested) Penguin'. Breeding endemic to New Zealand.

Order Procellariiformes; 'the tubenoses'

This order includes the Albatross, Mollymawks, and all the petrels. 

They are distinguished by their nostrils being enclosed in a tube that runs along the bill.

They include the largest of all flying birds; the Great Albatross reach wingspans of 3.6 metres

Thalassarche chrysostoma, 'Grey-headed Albatross'.

Family Procellariidae: Prions, Shearwaters, Diving Petrels and various Petrels 

Pterodroma gouldi, 'Grey-faced Petrel'. Breeding endemic to north island of New Zealand.

Pachyptila vittata, 'Broad-billed Prion'.

Pelecanoides urinatrix, 'Common Diving Petrel'. A tiny seabird that 'flies through waves'. I think Diving Petrels are potatoes with hummingbird wings. Because they only seen in colder oceans usually remote from humans, they are not commonly seen or known by most people. Because they are so small and fast, they are hard to photograph, and indeed even see.

Class Mammalia

Cetaceans

Lagenorhynchus obscurus, 'Dusky Dolphin'.

Cephalorhynchus hectori, 'Hector's Dolphin'. The smallest dolphin species in the world. Endemic to bays around the New Zealand coast.

Physeter macrocephalus, 'Sperm Whale'.

Order Carnivora

Pinnipeds

Family Otariidae: the 'Eared Seals', including sea lions and fur seals

New Zealand Fur Seals often expose their flippers to the sun to warm up.

Arctocephalus forsteri, 'New Zealand Fur Sea'.  Found around coast of New Zealand and southern Australia.

Places to experience Australasian temperate oceans

New Zealand has great coastline and rich temperate waters to explore. The seas off Kaikoura are incredibly rich with life, due to a drop off close to the coast. There is an interesting window into the underwater world through the Milford Sound Underwater Observatory. The rarely visited Snares Islands are south of Stewart island off the South Island, New Zealand.
