In many fish species, especially those from the sea, females are dressed modestly while males are true “fashionistas,” adorned like Spanish grandee. This is the case with the smarida fish. The males of this species are colorful, sporting stripes along their sides…
But the females don’t envy them. This is partly because they will eventually transform into males. It’s a remarkable phenomenon! All the eggs hatch into females, but after three years, they become… males!
Equally astonishing transformations occur in the marine fish known as the black sea bream. All the fish are born as males, but over time, each black sea bream is destined to become a female. Their hair-like covering is no joke either; in some species, it can reach up to 140 centimeters.
However, that fearsome horn isn’t made of bone like an elephant’s tusks, nor is it made of keratin like those of buffalo or bison. It consists of tightly compressed hair fibers. With a sharp knife, the terrifying weapon of the rhinoceros can be split apart, revealing a pile of hair.
