Sea dragon internal or external fertilisation?

Answer 1

Seadragons are like seahorses in that it is the male who carries the eggs The female will deposit up to 250 eggs (bright pink) onto the males tail where the eggs attach themselves to a "brood patch" where they will stay for the next 6 to 8 weeks where they receive oxygen from "cups" on this brood patch and they become "fertilised" which is external

Answer 2

Seahorses breed a little differently than most other sea inhabitants.

The male seahorse has a breeding pouch on the front of his abdomen. The female deposits her eggs (up to 1500 at a time) in this pouch when they are mating. The males then fertilize the eggs and carry them for 9 - 45 days (dependent on the breed of seahorse). When they are ready, the young, tiny seahorses are released from the pouch and the parents' role is done. The young are left to fend for themselves.

Answer 3

Seahorses use external fertilisation because they are not a mammal. Only mammals use internal fertilisation like humans.

Answer 4

internal
