A new marine research laboratory on Monterey Bay in California gave Frank Mace MacFarland the ideal setting to begin, in 1892, his lifelong study of sea slugs (nudibranchs). MacFarland became a world expert on nudibranchs—colorful mollusks that have no protective outer shell, and include some 3,000 species. MacFarland’s wife, Olive Hornbrook MacFarland, worked alongside him and painted the watercolors that illustrate his publications. Many sea slugs warn away predators with striking patterns and colors that advertise their powerful chemical defenses. Some species produce their own toxins, including sulphuric acid. Others store poisons taken from prey such as toxic algae.

Mottled in green, brown, and pink, this giant clam was spotted in the Fagalua/Fogama'a area of National Marine Sanctuary of American Samoa. 

Once nestled into a location on the reef, giant clams remain stationary throughout life, and play a major role in reef community structure. Like corals, giant clams have developed symbiotic relationships with algae called zooxanthellae. In return for shelter, zooxanthellae provide giant clams with nutrients they’ve photosynthesized!

Thinking in the Deep: Inside the Mind of an Octopus
In “Other Minds,” Peter Godfrey-Smith shows how the abilities of the octopus offer insight into the evolution of animal intelligence.
By Carl Safina

If we met an alien whose intelligence derived through an entirely separate provenance from ours, would we recognize the sparkle in each other’s eyes?

In “Other Minds,” Peter Godfrey-Smith hunts the commonalities and origins of sentience. He is an academic philosopher but also a diver. Watching octopuses watching him, our author considers minds and meanings.

Octopuses and cuttlefish — cephalopods — make surprisingly good foils here. Our last common ancestor, 600 million years ago, was a wormlike creature. Cephalopods are therefore an independent voyage into complexity.

“If we can make contact with cephalopods as sentient beings, it is . . . because evolution built minds twice over,” Godfrey-Smith writes. “This is probably the closest we will come to meeting an intelligent alien.” When seeking other minds, we find that “the minds of cephalopods are the most other of all…”

Ghostly critters from the deep sea: CIRRATE OCTOPUS   

Making a rare appearance just in time for Halloween, this ghostly-looking orange cirrate octopus was recently observed by MBARI’s ROV Doc Ricketts swimming over the Taney Seamounts. These finned octopuses belong to an order of animals called Cirrata named for the presence of hair-like structures called ‘cirri’ on their arms which may aid these animals in the capture of food.

Toriel will only give you 3 real uses/facts about snails out of the 72 uses for snails. The forth is a joke and she will not give any different ones after that, no matter how many times you reload. 
This means that she doesn’t want to tell us the 69 uses for snails…
clever Toby…. 

Anyway, let me go give more interesting facts about snails
69. Snails have both a penis and a female opening located behind their head, as almost all are hermaphrodites and possess both male organs and female organs, so they have to link with another snail and exchange sperm so they both can fertilize their eggs.
68. Snails can be carnivorous.
67. Some Snails have flattened shells inside their body with their mantle covering the shell.
66. Snails die in salt because it is soluble and causes all the water inside the snails cells to exit and become replaced with solute, this is called osmosis and diffusion.  This is why we can’t drink salt water or swim in salt water when we have bad burns destroying our skin. 
65. Snails grow new larger chambers of their shell as they get older, meaning the very inside of the spiral of the shell is from when they were smaller, and the chamber that is at the opening of the shell is the most recent.
64. Snails can have special “doors” to their shells called operculum, which are hard circular parts that can be retracted and sealed, allowing the snail to be protected and last longer without drying out. 
63. Snails have been eaten all over the world, not just in fancy French dishes. 
62. Some species of snails have “love darts” which are arrow shape spiny calcified barbs that they will attempt to stab the other snail they are mating with, the barbs will inject chemicals that inhibit the sperm of the snail that is stabbed with it, basically like poison that acts as spermicide. this means the snail that stabs its mating partner first will gain the advantage of not having to be the female of the mating relationship and will not have to produce and maintain the energy costing eggs. the stabbed partner will become the female and have to gestate the eggs. 
61. The study of snails is called conchology
60. due to the effects of buoyancy and high oxygen content in the deep ocean waters, the largest marine snails can grow up to  91 cm long and weigh up to 18 kg. The largest land snail can reach is 38 cm and 1 kg because of how heavy its shell is.

I could go on, but 59 more snail facts would take a long time to type out.
