Species with strong pair bonds:
* Harbor seals: While not strictly monogamous, they tend to stay with the same mate for several years, especially females.
* Grey seals: These seals form strong pair bonds that can last for multiple breeding seasons.
Species with less defined pair bonds:
* Elephant seals: Male elephant seals are highly competitive and tend to have multiple mates.
* Harp seals: They are known for their polygynous mating system, where males mate with multiple females.
Factors affecting pair bond strength:
* Species: Different seal species have varying social structures and mating behaviors.
* Resource availability: Abundant food sources may allow for more stable pair bonds.
* Environmental factors: Harsh environments may necessitate stronger pair bonds for survival.
Overall: While some seal species show strong pair bonds, others are more promiscuous. It's important to consider the specific species when discussing mating patterns.
