Cymatium lotorium
…is a species of triton (Ranellidae) which is widely distributed throughout the Indo-Pacific oceans. Like other tritons Cymantium lotorium is a predator and will feed on echinoderms and other molluscs by gripping them with its muscular foot and using its radula to saw through their hard shells/skin. Once it has finished “drilling” it will inject a paralyzing saliva into the prey which subdues the prey allowing C. lotorium to feed at its leisure.

MORE SNAILS WHEEEEE we took new photos of them today with Piippu

These are Achatina fulica f. white jade, they can be found from this post over here as well. They are already adults! <3<3<3 Miss Universum is 8.5 cm and Riviera 8 cm in shell length. We had a third one, who is seen in the post I linked, but he never really grew and died just recently. Rest in peace, sweet little Invisible Man. ♥

But these two, I really really REALLY love them ahhh they’ve already been showing each other their love darts, I can’t wait for them to lay eggs! Though… there’s always a possibility that neither of them is fertile, but I won’t give up hope! SNAIL BABBIES IHIHIIIIII

Corolla ovate - a rare sea butterfly     
This tiny sea butterfly spends its days floating in the ocean, feeding on plankton
by Becky Crew
FLOATING THROUGH THE ocean like a lonely spacecraft on a mission to smother its transparent hull in stars, Corolla ovate is a rarely encountered species of sea butterfly.
Found all around the world&#8217;s oceans at depths of up to 2km, this tiny creature is known to haunt the coast of Australia, in the Bismarck, Solomon and Coral seas up near the Cape York Peninsula and Papua New Guinea, and down south in the Bass Strait.
It&#8217;s delicate thing, at just 4cm long, and spends most of its days trying to avoid the enormous mucous webs laid out for it by carnivorous sea slugs called Cliopsis. Also known as sea angels, these formidable hunters are the sea butterfly&#8217;s own Doctor Who nightmare&#8230;

Pleurobranchaea californica 
&#8230; is a large snail (a sea slug in the family Pleurobranchidae) without a shell. It can get to over 8 inches long and live at depths to 400 meters (~1200 feet). Its mottled brown mantle resembles the muddy bottom on which it forages. It feeds on a variety of sand and mud bottom invertebrates, but has also been documented to eat small flatfish, and sometimes cannibalizes its own species! 
This species is a common inhabitant of the muddy seafloor observed using MBARI&#8217;s ROV Ventana at depths between 100 and 400&#160;m.

The Butterfly Snail (Limacina helicina) is a species of predatory swimming marine snail. They are a keystone species within Arctic pelagic ecosystems and are currently under serious threat.

They are being impacted by Ocean Acidification, due to pollution the ocean waters are becoming too acidic for survival. The corrosive waters off the West Coast of the U.S are dissolving the shells of these unique creatures and inevitably killing them. The decline of these will have major flow on effects to major marine ecosystems.

Otway Black Snail | ©Ken J. Beath 
The Otway Black Snail, Victaphanta compacta (Rhytididae), is a carnivorous land snail, only found in wet forests and cool temperate rainforests in the Otway Ranges, Victoria, Australia. 

The body of the snail is grey-blue to black; the shell is spherical with four whorls and varies from a glossy dark brown to black with tinges of yellow-brown on the inner whorl. The shell has a maximum diameter of 28mm and is positioned towards the tail of the body. The shell is thin, light weight and moderately flexible and comprised mostly of conchin [1]. 
Victaphanta compacta is regarded as Endangered species os the IUCN Red List [2].

Snail Consumes Worm With Frightening Efficiency

by Lisa Winter

Powelliphanta is a genus of carnivorous land snails from New Zealand, who are also known as amber snails. They can grow to be 91 mm (3.6 in) long, about the size of a fist. Earthworms are a staple of amber snail’s diets though it doesn’t seem like it should be much of a match-up. Worms are really slippery and wiggly and snails are pretty slow, right? So how do the snails capture their prey? …

Green snail - Rhinocochlis nasuta | ©Paul Bertner   (Mt. Kinabalu National Park, Sabah, Borneo)
Rhinocochlis nasuta (Dyakiidae) is an elegant land snail known from Borneo, with a compressed and small shell up to 24 mm.
The shell of this snail is levorotatory or sinistral, this means that the direction of rotation of the shell around its axis occurs in counterclockwise, so if the shell is placed with the apex upward then the opening of the shell is to the left side.
As the common name indicates, the body of the animal is of a bright green color, however, the shell is actually milky white, but is observed green because it is very thin and translucent.
