(qui ce una foto dove le uova sono sul vetro?)

in dei topic ho letto che le uova sono sul giallo.... vedi giallo nel buco?
Comunque mi sembrano solo conferme di quello detto precedentemente (Essendoci di mezzo Ike Olivotto, non c'e' da sorprendersi!).
- depongono in un "nido" o nella tana.
- i comportamenti cambiano durante la deposizione. In particolare il maschio difende la tana.
- le femmine di alcune specie cambiano i colori nel periodo della deposizione
- le larve nascono con bocca e occhi, quindi sono da alimentare da subito.
- le larve sembrerebbero intorno ai 3.5mm.
"Blennies attract mates near the holes or crevices in which spawning occurs. The females will often initiate courtship, some assuming new coloration for spawning. When the female enters the area the male engages in courtship behavior that can include changing into spawning colors, bobbing the head up and down at the mouth of the cave, and leading the female to the nest by swimming with an undulating motion. One the male may mate with several females. Males of some species apparently move toward an olfactory cue released by other males during spawning. (Thresher, 1984). The male is generally active during spawning, deterring predators, and afterwards guarding the eggs until hatching. Females may occasionally guard the nest as well. One male may mate with several females, brooding all the eggs in the same nest"
Blennies generally pass through a pelagic, postlarval stage after a short planktonic stage. The young pelagic fishes look different enough from their adult form that they were classified at one time as a separate subfamily. Transformation into the adult form occurs at some time after the postlarvae enter a littoral habitat. (Böhlke and Chaplin, 1994; Moyle and Cech, 2000; Wheeler, 1985)
Ecsenius species hatch into life at roughly 3.5 mm of total length and by the time they reach 12 mm they are nearly identical to adults in color and morphology
