| In the contemporary ocean, cysts tend to be most abundant in seas of temperate latitudes. |
| As a result, there is much less interaction between the lower troposphere air masses of the polar regions and middle latitudes. |
| They are found in all seas, at all latitudes, and from the intertidal to the abyssal zone. |
| At the mid-latitudes, the winds are called the westerlies, and at the highest latitudes, the winds are called the polar easterlies. |
| This contrasts with temperate and especially sub-tropical and tropical latitudes where keratose sponges can be common. |
| Further research using this approach in the high southern latitudes is underway. |
