How does a swordfish reproduce?
During spawning, male-female pairs form, but they reproduce through external (rather than internal) fertilization, where the female releases her eggs into the water column while the male releases his sperm. Once the sperm find the eggs, fertilization occurs.
How many eggs does a swordfish lay?
Depending on their size, females can produce anywhere from 1 million to 29 million eggs. They spawn multiple times throughout the year in warm tropical and sub-tropical waters.
What is the lifecycle of a swordfish?
Swordfish reach sexual maturity between 5-6 years of age and live up to 9 years. Little is known about the reproductive behavior of swordfish except that spawning tends to occur in warmer waters year round and during the spring and summer months in cooler regions.
Do swordfish regrow their swords?
Fishermen often catch swordfish with mangled swords, so breaking one isn’t fatal, but they do help their owners swim faster and feed. And they don’t seem to grow back, at least not for adults.
How many babies do swordfish have?
Remember that they can produce offspring in as little as three months and would continue to give more every after 4-6 weeks. Another possibility to consider is the fact that this fish can produce 150 babies in one birthing.
Are swordfish live babies?
Like other livebearing aquarium fish, swordtails (Xiphophorus hellerii) give birth to live young, or fry, rather than laying eggs. Although the swordtail’s gestation period is 28 days, it may be difficult to determine when she became pregnant.
How can you tell how old a swordfish is?
Swordfish ages are derived, with difficulty, from annual rings on fin rays rather than otoliths, since their otoliths are small in size.
Do swordfish live in groups?
They do not generally swim in groups or schools. Together with the marlin, it is one of the fastest fish in the ocean.
Has anyone been stabbed by a swordfish?
There have been very few reports of swordfish attacks on humans and none have resulted in death. Although there are no reports of unprovoked attacks on humans, swordfish can be very dangerous when provoked and they can jump and use their swords to pierce their target.
How often does a swordtail fish have babies?
A swordtail fish is a livebearer, which means they have live babies. At one time they can have between 10-60 babies but the average is 30-35 babies. After giving birth, she can get pregnant immediately and will give birth again in a month. If she is properly taken care of, she can give birth every month.
How does a sword fish reproduce at one time?
Swordfish reproduce by laying eggs, that is to say that they are oviparous. Female swordfish can lay anywhere between 1,000,000 and 30,000,000 eggs at one time and fertilization is external. The mother lays eggs and allows them to develop externally from her body. It is a common method of reproduction for many fish.
How big is a fully grown Baby Swordfish?
Marine biologist Juan C. Levesque captured a stunning close-up of a tiny baby swordfish on his finger tip. “Gladiator of the sea”, the minuscule creature can be measured in millimetres, but when fully grown, reaches 3 meters in length!
Can you save a pregnant swordtail fish fry?
Mostly, swordtails and other livebearers eat their babies. Therefore, if you already have a separate aquarium tank in your home, you can transfer the pregnant swordtail there. If you do not have one, you can still save your fry. Here are the steps to take:
