Pez Mariposa - Pez Ángel - Pez Cirujano

Grupo 1- Discos y óvalos / Coloridos: La primera categoría de peces de forma ovalada y de disco es muy importante. Son coloridos, grandes y muy obvios y las tres familias principales que componen el grupo se pueden encontrar en casi todas las inmersiones en Costa Rica.

Longnose Butterflyfish (Forcipiger flavissimus)

The yellow longnose butterflyfish is widespread throughout the tropical waters. It is a small fish which grows up to 22 cm in length. Being territorial, yellow longnose butterflyfish patrol their patches of coral with a monogamous partner.

Barberfish (Johnrandallia nigrirostris)

Barberfish are often seen in small groups swimming slowly a few feet above the bottom. The key feature of the barberfish is the black ring around its eye. The barber has a black eye from giving someone a bad haircut. (Size 3-4”, max. 6”)

1. Disks and Ovals / Colorful

The first category of disk and oval shaped fish are very important to learn. They are colorful, large and very obvious and the three main families that make up the group can be found on almost every dive.

2. Silvery Fish

Silvery fish have many different family members, though we will look at just a few representatives. As opposed to the colorful butterfly, angel and surgeonfish, the silvery fish tend to blend in better in open water and are usually not found near the colorful bottom.

3. Sloping Head / Tapered Body

This third group of “fish-like” fish, are very important to learn. The are common on most dives and are also highly sought after as food fish. It is especially important to monitor these fish to provide data for fisheries management. Snappers can be very difficult to tell apart from the similarly shaped grunts. One helpful hint is to look at their tails. Snappers tend to have straight, flat tails. They are also known for their habit of snapping their mouth open and shut when caught on hook and line. They have very sharp canine teeth that can provide a nasty bite to the unsuspecting angler. Look closely on your next dive and you may see the small teeth protruding from the side of the mouth. Grunts on the other hand, have slightly notched tails. They get their name from the grunting sounds they emit when threatened. These sounds are created by rubbing together bony teeth plates located in the back of the throat. Since the teeth are in the throat, a diver will never see protruding teeth on a grunt, only big blubbery fish lips.

4. Small Ovals / Damselfish

While divers tend to first notice the larger, more obvious fish on a dive, after a short while the challenge to find new species leads them to change their search image to look for smaller, previously unnoticed fish. Generally, the first new species a diver will encounter will belong to the small oval shaped group. This group is broken into the damselfish and their close cousins the chromis. Damsels are like the surgeonfish in that they eat algae. They do not roam around grazing, but rather tend to small algae gardens like a farmer. These areas are guarded fiercely as the algae farm is the damsels food source. For that reason you can think of the damselfish as not just territorial, but Dam- selfish with its territory. Many damselfish have distinctly different colors as juveniles, often being much brighter and more colorful when they are young and becoming drab with age. (much like us humans!) For this reason, the juveniles have been heavily collected for the aquarium trade and are under heavy fishing pressure. As part of the REEF Fish Survey Project, divers are asked to monitor the juveniles and adults separately in two of the damselfish species – the Cortez damselfish and the giant damselfish.

5. Heavy Body / Large Lips

Heavy bodied, large lipped fish belong to the seabass family. We tend to refer to the larger seabasses as groupers and the smaller seabasses as bass or basslets. These fish are extremely important food fish and are under increasing threats from heavy fishing pressures. Monitoring these fish can help provide valuable data to aid in their protection. Most seabasses are hermaphrodites, meaning the same fish will be both a male and a female during its lifetime. The groupers are all born female and later change sex to become male. Most large groupers also congregate each year to spawn at a specific location, making them easy targets for emerging positioning and fishing technology.

6. Swim with Pectorals / Obvious Scales

The fish in this group all use their pectoral fins to swim with rather than the traditional tail swimming of most other fish. The scales are also quite large and obvious. These fish can also be hermaphrodites, like the groupers, with some fish changing sex and others staying the same. Intermediate and adult fish often have very different appearances compared to the always-male terminal phase. This means learning two colors to be able to ID the same species of fish. Most of the pictures shown in this curriculum are terminal phase males, unless noted.

7. Redish / Big Eyes

This group of reddish fish is normally not seen during day dives due to their nocturnal nature. The reddish color helps them blend in at night and the large eyes help them to see better.

8. Small, Elongated Bottom Dwellers

The small bottom dwelling fish often make up the most interesting fish to watch during your dive. Their approachable nature and interesting behaviors make them great fishwatching finds. Blennies tend to be slightly larger than gobies, but are most easily recognized by their curved body posture and expressive faces. Gobies, though similar in their habitat requirements, tend to sit flat and straight on the bottom. The jawfishes actually live in a burrow in the sand that they excavate and maintain.

9. Odd-Shaped Bottom-Dwellers

This category of fish is made up of families and species that didn’t quite fit anywhere else due to their unique body shapes.

10. Odd-Shaped Swimmers

This group of fish contain families that are unusual in their shape, but are swimmers rather than bottom dwellers.

11. Eels

Though looking like snakes, eels are fish. There are several different types of eels, and we will look at two – garden eels that live in burrows in the sand and moray eels. Moray eels have a bad reputation mainly due to the constant opening and closing of their sharp toothed mouths. However, this is not a threat to divers, as this action pumps water through their gills. Most eels are actually very shy.

12. Sharks & Rays

Even though the sharks and rays are cartilaginous (their skeletons are made of cartilage instead of bones), they are still referred to as fish and count during our surveys.

5 Fun Facts - Butterfly Fish

FUN FACTS Butteflyfish - Angelfish - Surgergeonfish

Los peces mariposa se encuentran entre las criaturas más coloridas que encontrarás en los arrecifes de coral del mundo. Estos encantadores peces pertenecen a la familia Chaetodontidae y son famosos por su apariencia llamativa y comportamientos fascinantes. Aquí encontrará todo lo que necesita saber sobre estas maravillas submarinas, junto con algunos ´Fun Facts´:

Orígenes del nombre: El nombre "pez mariposa" se deriva de sus elegantes y aleteantes movimientos bajo el agua, que se asemejan al delicado y elegante vuelo de las mariposas.

Aspecto deslumbrante: los peces mariposa son famosos por sus patrones vibrantes e intrincados. Sus cuerpos suelen estar adornados con rayas llamativas, manchas y colores llamativos como azules eléctricos, amarillos y naranjas. Esta llamativa apariencia no sólo les ayuda a mezclarse con el coral, sino que también sirve como advertencia a los depredadores potenciales de que son tóxicos o desagradables.

Mariposas sociales: los peces mariposa son conocidos por formar parejas monógamas que permanecen juntas durante al menos 3 años y, a veces, de por vida. A menudo se les ve nadando cerca de su pareja, lo que fortalece su vínculo y ayuda a defender su territorio.

Dieta especializada: los peces mariposa tienen una dieta única que consiste principalmente en pólipos de coral, pequeños invertebrados y algas. Sus bocas largas y delgadas están perfectamente adaptadas para alcanzar espacios reducidos dentro del coral y extraer sus presas.

Especies clave: los peces mariposa desempeñan un papel crucial en el mantenimiento de la salud de los arrecifes de coral. Al alimentarse de organismos nocivos que pueden crecer demasiado y dañar los corales, ayudan a mantener el ecosistema en equilibrio.
