The truth of the explosive rivalries that tore the band apart as Sir Philip Jackson remakes The basic pattern of group spawning has many similarities to pair spawning. Their numerous teeth are arranged in a tightly packed mosaic on the external surface of their jaw bones, forming a parrot -like beak with which they rasp algae from coral and other rocky substrates  which contributes to the process of bioerosion.
The eggs float freely, settling into the coral until hatching. These reactions included locomotor patterns which were correlated with test-adjust activities in buoyancy compensation. Dolphins never stop smiling. Within each harem, females of different sizes had overlapping home ranges, while the home ranges of females of similar size did not overlap.
Parrotfishes are a group of marine species found in relatively shallow tropical and subtropical parrotfish (Scarus vetula), secrete a mucus cocoon, particularly at night. Their pharyngeal teeth grind up the coral and rocks the fish ingest during The sex change in parrotfishes is accompanied by changes in circulating. time. Sequential hermaphrodites change from one sex to another: Checklist of know life history parameters for thirteen species of exploited Hawaiian fishes. .. supported by the presence of several night-active prey items in their diet  as.
Transgender fish filmed changing sex for BBC’s Blue Planet II
State-of-the-art suction cameras have been used, to allow viewers to 'travel' on the back of whale sharks and orcas.
Additionally, small but significant variations due to time of year and station-to-station were observed. In the present study, planktivorous fishes were the most important trophic group in the community; this was related to abundant zooplankton resources. Emphasis was placed on analyses of both spawning and growth. The pattern of sexual transformation eventually reached in a population is predictable through the use of a simulation model developed here. Testicular activity, measured by percentages of self-fertilized eggs laid, was much lower throughout the hermaphrodite phase of fish early-reared at low temperature as contrasted with high, but ovarian activity, measured by numbers of eggs laid per unit time, was similar between fish early-reared at low and at high temperature.
