Today we went scuba diving at pleasure reef and spanki
reef. Both reefs we saw a lot of
diversity and many different kinds of fish, sharks, and eels. The one fish that really stuck out to me was
the blue parrotfish!!! These parrotfish are
a very vibrant blue and they have these beaks that almost look like buck teeth. They use these teeth to scrape algae off of
rocks and corals and they even ingest these corals and rocks!!! When they ingest these corals and rocks, they
actually have more teeth in their throats that allow them to break up these
corals/ rocks up into sand which they later eliminate. The sand that the blue
parrotfish excretes helps contribute to the formation of sandy beaches in the Caribbean!!

Like many other fish the blue parrotfish goes through color
changes while growing into adult. When
the blue parrotfish is young, they have a yellow spot on their heads, but as
they grow the spot goes away and they start to turn into a purple color, and
then as adults they turn into the very vibrant blue color. These changes as
growing aren’t as crazy as those of a stoplight parrotfish, but they still help
us to identify around what stage in their life they are at.
Stoplight Parrotfish |
The other fish that I saw a lot of almost every day was the
stoplight parrotfish. This fish gets its
name because as they grow from the initial stage to their adult stage, they are
many different colors. When a stoplight parrotfish
is born, they are all born as females, they start of as a dark brown color with
white spots, and then going to a more colorful pattern with checkered scales,
bright red fins, and a marbled head. But
that’s not all, they change again to even more colorful scales. The matured female turns from a female to a
male that has a blueish green head, bright green scales, and a large yellow
spot above the gills. That’s a lot of
changing for one fish to go through!!
