5.1 Horizontal Migrations

5.1 Horizontal Migrations

Marine Science

= Large-scale movement of marine organisms.

----------------------------------

Note: "Horizontal" is in relation to the ocean surface.

​

​Horizontal Migration

*Moving between feeding & breeding grounds

*Moving from depleted to fresh feeding patches

*Offspring moving out of parental territory

​Seasonal Migration

Multiple Select

Which of the following horizontal migrations are seasonal?

• moving out of destroyed habitat

• moving out of parent's territory

• moving between feeding & breeding grounds

• moving to a new feeding patch

■Habitat loss

–Construction

–Pollution

–Change in salinity

■Climate shifts

–Temperature

–Sea level rise

​

​Permanent Migrations

Multiple Select

Which of the following horizontal migrations are permanent?
