The brood pouch may have moved locations when there was strong a correlated selection for a prehensile tail and diminutive size, resulting in a very small, trunk brooding organism. [15] Viviparity and male-pregnancy in Syngnathidae have a complex evolutionary history with many independent origins of similar traits.
Other distinctive pygmy seahorse characteristics include a fleshy head and body, a very short snout, and a long, prehensile tail. With their short snouts, they have the appearance of baby animals. Pygmy seahorses are 14–27 millimetres (0.55–1.06 in) long from the tip of the tail to the end of the snout, so that their vertical height while ...
Pregnant male pipefish can absorb nutrients from their broods, in a manner very similar to filial cannibalism found in many other families of fish. The smallest eggs in a brood of various egg sizes usually have lower survival rates than larger ones due to the larger eggs having a longer-lasting food source (absent contributions from the father ...
A pregnant Southern platyfish. Pregnancy has been traditionally defined as the period of time eggs are incubated in the body after the egg-sperm union. [1] Although the term often refers to placental mammals, it has also been used in the titles of many international, peer-reviewed, scientific articles on fish.
Their prehensile tail is composed of square-like rings that can be unlocked only in the most extreme conditions. [17] They are adept at camouflage, and can grow and reabsorb spiny appendages depending on their habitat. [18] Unusual among fish, a seahorse has a flexible, well-defined neck.
