What does the pteropod use to move itself through the water
Supporting Sentence: She was aboard a research ship in the North Pacific, carrying out experiments on a species of pteropod – small molluscs with shells up to a centimetre long, which swim in a way that resembles butterfly flight, propelled by small flaps. these flaps are used by Pteropods to move through water.
What does pteropod eat

Why are pteropods in danger
Pteropods are at risk to ocean acidification because their thin shells are sensitive to changes in ocean chemistry. In more corrosive water, pteropods can have trouble growing their shells because there are fewer carbonate “building blocks” in the seawater. In extreme cases their shells can dissolve.
Can pteropods swim
Swimming Mollusks
Ptero stands for wing and pod for foot. Also called sea butterflies, these snails use their feet as wings for swimming. There are many different species measuring a few millimeters to several centimeters. Pteropod mollusks have two wings on either side of a soft body, sometimes protected by a shell.
What is the range of pteropod
Pteropods are found in all major oceans, usually 0–10 metres (0–33 ft) below the ocean surface and in all levels of latitude. Pteropods can be found lower than 10 meters, but in less amounts in terms of biomass, however, pteropod distribution is more spread out deeper based on findings.
What is the diet of a pteropod
Most pteropods enjoy a nice salad of plankton like diatoms—or, after the seasonal algae bloom is over, an entrée of zooplankton like foraminifera or copepods.
Why are pteropods dying
That's where climate change comes in. Carbon dioxide from human activities ends up in the ocean, increasing the acidity of seawater. As the pH level falls and water becomes more corrosive, calcium carbonate in pteropod shells dissolves.
How old are the pteropods
Ages are given in million years ago (Ma), with 95% credibility intervals in brackets (see also Fig. 2A). Our phylogenomic time-tree dates the origin of pteropods to the early Cretaceous (139.1 Ma with 95% credibility interval [CrI] 188.2 to 111.4; Fig.
Who eats 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.
