Pteropods are little mollusks (related to snails, slugs and squid) that drift around in ocean currents, feeding on nutrient-rich plankton. Their rich diet makes them delicious to many fish. Seals eat many fish, and sharks eat seals and fish, so there it is: not even 6 degrees of shark separation.
What does a sea butterfly eat?
The sea butterflies have developed a net of mucous-webbing for inactively catching microscopic organisms like small crustaceans, but it can also be used to catch sinking particles, so-called “flux feeding.” The snails actively sort out the food they gathered and expel particles they can’t digest.
What eats a snail in the ocean?

Why is marine snail called a sea butterfly?
It has earned the name “sea butterfly” because of its elegant swimming style, and “potato chip of the sea” because of its importance as a food source for so many Arctic marine species from zooplankton to seabirds to fish.
What species eat Pteropods?
All kinds of organisms eat them, from tiny krill to fish to whales. And other animals like seals (primary prey for polar bears) rely on the fish that eat the pteropods. These “sea butterflies” are also a major food source for North Pacific juvenile salmon, which we humans enjoy.
Are Sea Angels poisonous?
They are neither eggs nor jellies, and they do not sting. Also called sea angels, these animals are completely harmless.
Are sea angels and sea butterflies the same thing?
They have larger, broader parapodia, and most of that species retain a shell; they are commonly known as sea butterflies. Sea angels are gelatinous, mostly transparent, and very small, with the largest species (Clione limacina) reaching 5 cm. This is about twice as fast as their prey, the sea butterfly.
How long can a snail live without food?
Most snails can survive for weeks and up to a couple of months without eating. Scientific studies on snails have shown that specific species can live up to eight months without food.
Are Sea Angels and sea butterflies the same thing?
Do sea butterflies bite?

Do you think pond snails are good for your pond?
They’re the little scavenging janitors of your pond. In a well-kept pond, though, I disagree with this view. Certainly, pond snails will get rid of some algae in the pond, and some of the debris. However, they will not have a significant effect on the problems that most pond owners face with water health.
Which is better for algae, snails or slime?
Snails might help if you’ve got a bad string algae problem. However, they’ll prefer to feed on the slime algae that actually helps to use up the nutrients that string algae feeds on. If you’re looking for an easy fix for string algae, there are better ways than snails. So, snails aren’t the natural,…
