Seasonal Seas..


       After the whale shark, the basking shark is the largest living fish. It moves slowly, and gradually through the water filter feeding. It has a greatly enlarged mouth and highly developed gill rakers. The color of the basking shark is usually a grayish, brown and seems to have a mottled appearance. The basking shark has very small and numerous teeth, often 100 per row. Basking sharks are a migrating species and are believed to overwinter in deep waters.

Blue Planet: Frozen Seas: Arctic Fox

ARCTIC FOX

The arctic fox lives in some of the most frigid extremes on the planet. This fox has several adaptions including its deep, thick fur, a system of countercurrent heat exchange in the circulation of paws to retain core temperature, and a good supply of body fat. The arctic fox has short muzzle and legs, and short, thick ears. Very little surface area on this fox is exposed to the cold, so very little heat escapes the body. Another adaption for this animal would be it's furry paws. They allow it to walk on ice in search of food. The arctic fox's hearing allows it to hear prey underneath the snow. When it finds prey, it pounces and punches through the snow to catch its victim. Its fur changes color with the seasons: in the winter it is white to blend in with snow, while in the summer months it changes to brown.

The Awesome Ocean: Man of War

MAN OF WAR

The Man of War has a gas filled bladder that causes it to float across the water. So unlike normal jellyfish, the Man of War does not swim underwater.


The Man of War is in the Animalia kingdom and they Hydrozoa Class.
It's in the Siphonophora order, the Physalia genus, it's species is P. Physalis, and it's phylum is Chidaria.


Because of the Man of War's gas filled bladder, it moves along by the tides and the wind.
This creature is most commonly found in the tropical and subtropical regions of the Pacific and Indian
ocean.

Ocean Science Video

During the video we learned about several different creatures. It talked about plankton, silky shark, cleaner fish, spinner dolphin, common dolphin, sei whale, sardines, striped marlin, manta ray, surgeonfish, yellowfin tuna, blue shark, and sunfish. I think the most interesting looking creature they showed was the Sunfish. It was an extremely odd looking fish and I feel like I should have one as a pet. They made it seem like a gentle, peaceful fish. Sunfish eat jellyfish which I give them props for.
