How about russel for male betta fish

Female eggs are appearing in the testes of some male fish in Illinois, a new study shows.

The eggs of fish and are jellylike. Cartilagenous fish (sharks, skates, rays, chimaeras) eggs are fertilized internally and exhibit a wide variety of both internal and external embryonic development. Most fish species spawn eggs that are fertilized externally, typically with the male inseminating the eggs after the female lays them. These eggs do not have a shell and would dry out in the air. Even air-breathing amphibians lay their eggs in water, or in protective foam as with the Coast foam-nest treefrog, .

Finally, sexual symbiosis may be an optional strategy in some species of anglerfishes. In the , females carrying symbiotic males have been reported in and —and others that were not still developed fully functional gonads. One theory suggests the males attach to females regardless of their own reproductive development if the female is not sexually mature, but when both male and female are mature, they spawn then separate.

Some male ocellated wrasse build seaweed nests to attract females. The fish are found in the eastern Atlantic and throughout the Mediterranean Sea. Some male ocellated wrasse build seaweed nests to attract females. The fish are found in the eastern Atlantic and throughout the Mediterranean Sea. Scientists from the U.S. Fish and Wildlife Service and the U.S. Geological Survey fish in 19 national wildlife refuges in the U.S. Northeast, including Missisquoi. Their conclusion: An astonishing 60 to 100 percent of all the male smallmouth bass they examined had female egg cells growing in their testes.When it comes to sex, some male fish can't catch a break. In species such as the ocellated wrasse, females prefer to mate with "nesting" males that build handsome seaweed nests, court females and care for eggs over smaller, less colorful "sneaker" males. Forgoing any courtship or paternal duties, these males instead wait for a female to release her eggs near a nesting male before sneaking up and inundating the nest with large numbers of sperm. To counter, nesting males release fewer but faster sperm. Scientists have thought that in this fish species and the two types of sperm competed to fertilize the eggs, with the outcome completely out of the female's fins. Now, a new study, which was published today in , finds that ocellated wrasse females hold more sway than researchers realized. Their experiments reveal that the ovarian fluid females release with the eggs creates conditions that increase the speed and accuracy of sperm moving toward the eggs. That favors the already swift swimmers of the nesting males, frustrating the sneaker males and their sperm. Who runs the world? As Beyoncé and these female fish know, it's clearly the girls.Over the past decade, feminized male fish have been discovered in 37 species in lakes and rivers throughout North America, Europe, and other parts of the world. Experts say the new discovery in protected wildlife refuges is worrisome because it suggests that pollution may be even more pervasive than previously thought.Gender in fish isn’t always straightforward. Some species of fish—including clown fish, grouper, and gobies—are hermaphrodites, meaning they naturally have both male and female sex organs. They are born with the ability to change their gender—it’s a special adaptation that some species have evolved to improve their chances at reproducing.
