Anyone interested in returning to the oceans?
Have fun and enjoy!
Swan1. What are a group of sea birds called? A Wreck.
2. Purple sea anemones and clownfish enjoy sharing a unique living arrangement: What is this living relationship called? Symbiosis.
3 What are a group of herring called? Army/ Shoal.
4. What are a group of jellyfish called? Brood/ Smack.
?5. What is the definition of a plant-eating animal? Sea urchins are a good example of a marine animal that feeds on kelp, for instance. Herbivore
6. A species that occurs naturally in an area (i.e. is not introduced) is referred to as what type of species? Native.
7. A species that can live in many different habitats and can feed on a number of different organisms is referred to as what? For example, shore crabs on the Pacific coast live in a wide variety of habitats, such as mud, sand and rock, and feed on everything from the algae growing on rocks to invertebrates to detritus. Generalist.
8. What are microscopic algae with plate-like structures composed of silica called? Diatom.
9. To protect themselves against predators, many animals acquire coloring and markings to match and conceal themselves in their usual surroundings. For example the nudibranch (sea slug), Rostanga pulchra, is practically indiscernible from the red sponges on which it lays its eggs. What is this phenomenon known as? Cryptic Coloration.
10. What is a species which no longer exists called? Extinct.
11. What is the broadest classification for animals called? A Phylum.
12. This term refers to the form and structure of an organism, in particular its outside features. What is this term? Morphology.
13. What is the name of the zone of the ocean that extends from 1000m to 4000m below the surface of the ocean called? Bathypelagic Zone.
14. Pelagic organisms that are free-swimming and so whose movements are independent of the tides, currents and waves are called what? Such animals include fish, whales, squid, crabs and shrimps. The distribution of these characters is limited by temperature and nutrient supply and decreases with decreasing depth. Nektology.
Thank you everyone! Excellent job!

Well Actually, bluefin Tuna and some other species are neither warmblooded nor coldblooded. They are species in between, meaning that they selectively warm parts of their body.
However, http://marinebio.org/species.asp?id=236
Atlantic bluefins are homeothermic ("warm-blooded") and are therefore able to thermoregulateexternal link keeping their body temperatures higher than the surrounding water, which is why they are so well adapted to colder waters.
Description & Behavior
Atlantic bluefin tuna, Thunnus thynnus (Linnaeus, 1758), aka blue fin tuna, blue-fin tunny, bluefin tuna, horse mackerels, northern bluefin tuna, and squid hounds..., are regarded as one of the most highly evolved fish species and one of the most prized fish in danger of overfishing. Tuna, originating from the Greek word meaning "to rush," usually swim at speeds of 1.5-4external link knots, can maintain 8external link knots for some time, and can break 20external link knots for short periods. These are one of the most magnificent fishes in the sea. One fish can sell for hundreds of thousands of dollars. A 342external link kg tuna sold at Tokyo's Tsukiji fish market for 32.49 million yen ($396,700 US dollars), the highest price for a single fish since record-keeping began in 1999, that's 95,000 yen ($1,157) per kg!
Atlantic bluefin tuna are the largest member of the Scombridae Family (albacores, bonitos, mackerels, tunas). They are one of the largest bony fishes and can reach lengths of up to 3external link m, although they are more commonly found from 0.5-2external link m in length. Adult weights range from 136-680external link kg, although the upper weight range is rare, especially now. They can dive as deep as 914external link m, and are known to swim long distances as they are a highly migratory species.
Atlantic bluefins are dark blue to black on their dorsal (upper) surface and silvery ventrally (underneath). Bluefins are known for their finlets that run down their dorsal (upper) and ventral (lower) sides toward their anal fin. There are 12-14 spines in their first dorsal fin and 13-15 rays in their second dorsal fin. Their anal fin has 11-15 rays. The average natural lifespan of bluefin tunas is 15-30 years.
Atlantic bluefins are homeothermic ("warm-blooded") and are therefore able to thermoregulateexternal link keeping their body temperatures higher than the surrounding water, which is why they are so well adapted to colder waters.

What is being described is the unique abilities of the "mesotherm"...truly amazing animals that are neither exotherms nor endotherms. Interestingly enough, Tuna fall into this category.
"... analysis revealed that dinosaurs sit somewhere between the endothermic and exothermic extremes, epitomized by most mammals and reptiles. They couldn’t control their body temperature as precisely as a horse or human; equally, they weren’t as dependent on their environment as a snake or lizard. “The data pointed to dinosaurs not being quite like a reptile or a mammal, but to weird things like great white sharks, leatherback turtles, and tuna.”
Great whites and tuna are mostly cold-blooded but their hard-working muscles naturally heat their blood. In most fish, the warm blood would lose its heat as it travels to the gills for a dose of oxygen. But in these fish, the vessels are arranged so that the warm blood from the muscles travels past cold blood from the gills, and heats it up. They create body heat, and keep that heat in their bodies—a trick that can keep certain body parts up to 14 degrees Celsius hotter than the surrounding water...."

So very interesting! 2001/ 2010 Space Odysseys have left so much to the imagination and to interpretation stretching from the monolith to the eventual 'star child'. And, while the Romans named the planet after their god, Jupiter, I have always considered/ defined Jupiter as a goddess (with her powerful personality as she rearranged the solar system and boasts 67 moons). In the Space Odysseys, Jupiter is also being considered as female, and it is she who will bring forth the new birth of man and evolution. This is the only time in which I have seen this interpretation. I wonder if, hypothetically, Jupiter should have become a star....

Jupiter is exothermic. Produces more internal heat than it absorbs from the sun. Holst's The planets Jupitor score has always been one of my favorite pieces of classical music,...Mars a close second. John Williams based The Empires theme from Star Wars on Holst's Mars score.

The Ariane 5 Rocket heavy lift from ESA (European Space Agency ) in Kourou, French Guiana has successfully launched two satellite passengers this afternoon.
Arianespace has successfully launched two telecommunications satellites: Thor 7 for the private Norwegian operator Telenor Satellite Broadcasting (TSBc), and Sicral 2 for the operator Telespazio, on behalf of the Italian Ministry of Defense and the French defense procurement agency DGA (Direction Générale de l'Armement, part of the Ministry of Defense).
Congratulations Arianespace on another successful launch!

What is generally considered the deadliest creature on earth, besides humans. Deadliest defined as causing the most human deaths yearly by its actions?
Posted : April 27, 2015 6:55 am
Mosquitoes.
Mosquitoes kill 163,780 more humans than all the other “dangerous” animals combined (humans are the second deadliest animal).

Nasty creatures! Does anyone know what they are good for?

You'd think not but in the case of mosquitos there are many animals, mainly bats that rely on them greatly for food. Some species of bats can eat over 500 of them an hour. One could argue then why not take out mosquitos and bats, bats as well serve just as important of a role if not more so than mosquitos. Some even help to pollenate plants just as bees and some birds do.
Aside from bats many aquatic species that also rely on them for a food source due to the fact that mosquitos are laid, hatched and semi-raised in water.
As tiny as they might be they also pollenate some plants.
Nonetheless when push comes to shove they might be annoying but we would miss them greatly due to the amount of food chains that would collapse and species of plant and animal that would be forced into extinction.
One can also say that they are a indiscriminate factor in population control.
Live in an area with lots of mosquitoes? Build a couple of bat houses.

Thanks Alana! Now I know what is going on at my house. When we first moved here we had tons of bats. In the last few years we have had more and more mosquitoes and I never see bats anymore. What has happened to all the bats? We need to get them back.
