Part one is here. Part two is here. All new kids, nobody knew me, a chance to start over with a clean slate. I felt some amount of guarded optimism then. I was never exposed to much church type stuff until Mom found religion in a big way upon becoming pregnant with what will soon be my baby brother.

So far, all I really know about Christianity is that Mom says it turns bad people into good ones. Sounds like what the world needs more of if you ask me. That meant moving us all into a new, larger house.

Unsolicited donations by individuals in our community help to fill the gap where Fish Tacos fall short. The MTI Dental Van has been coming four times per year, and Fish for Teeth plans on keeping that schedule even though Covid-compliancy means the dental van can only utilize one of the two dental chairs available, which reduces the patients by half. Instead of fulfilling half the need, Fish for Teeth has doubled-down and is hosting the dental van for twice as long. The ACH grant does not cover all the costs, so Fish for Teeth will keep to our grindstone, cranking out Fish Tacos to pay the bills that will make this service possible and accepting donations from individuals.

Kiwanis appear like food-service angels, creating miracles in the Fish Taco realm. And a very abbreviated list of individuals: Dr. It takes a village to provide good dental care for all on San Juan Island, and thanks to our generous community we are achieving that goal. If you value the efforts of Fish for Teeth and would like to lend financial support, please donate at fishforteeth.

Despite looking doctored, the toothy critter may be a real, live triggerfish that inhabits tropical seas around the globe, reports National Geographic. The triggerfish uses its people-like teeth to crunch crabs and sea urchins, which they flip over to get at the soft underbelly beneath, as demonstrated in this fascinating video.

Scrawled Filefish Aluterus scriptus approx. Taxonomy This species was described as Aluterus scriptus by Osbeck in Synonyms appearing in past scientific literature referring to this species include Balistes laevis BlochBalistes liturosus ShawBalistes ornatus ProceAluteres pareva LessonAluteres personatus LessonAluterus venosus HollardAluterus renosus HollardAlutera picturata Poeyand Alutera armata Garman Common Names English language common names are scrawled filefish, broom-tail file, broomtail filefish, filefish, scrawled leatherjacket, scrawled tilefish, scribbled filefish, scribbled fish, scribbled leather jacket, scribbled leatherjacket, scribbled leatherjacket filefish, scrolled filefish, and tobaccofish.

Geographical Distribution The scrawled filefish is circumtropical in distribution, ranging in the Western Atlantic from Nova Scotia, Canada and the northern Gulf of Mexico south to Brazil. In the Eastern Atlantic, it is found at St.

Habitat Associated with lagoons and seaward reefs, the scrawled filefish may be found in subtropical waters at depths from feet m but more typically seen at feet m.

It is also sometimes observed swimming under floating objects with juveniles traveling with weed rafts in the open ocean until reaching a large size. Juvenile scrawled filefish often swim in a vertical, head-down position when associated with drifting vegetation to avoid being detected by potential predators.

In addition to camouflage, filefish use spines for protection from predation. When threatened, the filefish will dive quickly into a crevice in the reef, wedging itself into the shelter by erecting the dorsal spine on its head. This large spine is locked into place by the smaller spine located behind it while another spine located on the belly extends to further securely wedging the fish in the crevice.

This behavior is also used when the filefish rests on the reef at night. The upturned mouth is small and opens above center line and the snout is concave. The openings of the gills are oblique and the pelvic fin is absent.

The caudal fin is long and rounded with a back edge that is often ragged. In addition, the maximum documented weight of this fish is 5. The females lay demersal eggs in safe areas such as a depression in the sand, then the male comes along and fertilizes them. The male or female will guard these fertilized eggs from predators and will attack any intruders that approach too closely.

Upon hatching, the female will take care of the young fish. Importance to Humans In addition to being considered a gamefish in some locations, this species is also often collected for the aquarium trade. If the flesh of this fish is eaten, caution should be taken as there have been reported incidences of ciguatera poisoning. The IUCN is a global union of states, governmental agencies, and non-governmental organizations in a partnership that assesses the conservation status of species.

Join the Project Noah Team.Pacu and piranha do not have similar teeth, the main difference being jaw alignment; piranha have pointed, razor-sharp teeth in a pronounced underbitewhereas pacu have squarer, straighter teeth, which are uncannily similar to human teethand a less severe underbite, or a slight overbite.

The common name pacu is generally applied to fish classified under the below listed genera. Each of these groups contains one or more separate species. For example, the fish often found in pet stores known as the black pacu and red-bellied pacu typically belong to the species Colossoma macropomum and Piaractus brachypomusrespectively. When the large fish of the genus Colossoma entered the aquarium trade in the U.

In the Brazilian Amazonthe term pacu is generally reserved to smaller and medium-sized fish in the MetynnisMylossomaMylesinus and Myleus genera. Colossoma macropomum are known as tambaqui, whereas Piaractus brachypomus is known as pirapitinga. Pacu, along with their piranha relatives, are a characin fish, meaning a kind of tetrabelonging to the Characiformes order.

The ongoing classification of these fish is difficult and often contentious, with ichthyologists basing ranks according to characteristics that may overlap irregularly. DNA research sometimes confounds rather than clarifies species ranking. Ultimately, classifications can be rather arbitrary.

Pacu, along with piranha, are currently further classified into the family Serrasalmidae formerly a subfamily of Characidae. Serrasalmidae means "serrated salmon family" and refers to the serrated keel running along the belly of these fish.

However, dental characteristics and feeding habits further separate the two groups from each other. Pacus are native to tropical and subtropical South America. Here they form part of the highly diverse Neotropical fish fauna. Their habitat preferences varies significantly depending on the exact species. Several species are migratory. Pacus have been introduced to the wild in many places outside their native range, both in South America and other continents.

They are sometimes released to increase the local fishing, but others are released by aquarists when they outgrow their aquarium. This is illegal in many countries and strongly advised against. Pacus have become established in Puerto Rico and singles have been caught in numerous U.

Clair in and a single in Lake Huron in Some state wildlife authorities have advised home aquarists who wish to get rid of overgrown pacu to cut the heads off the fish and dispose of them as garbage.

An angler fishing on the river Seine in ParisFrance caught a pacu in August The fish bit one of the fishermen, leading to a general warning being issued in the region, until the origin of the fish can be determined. In Julytwo pacus were caught near Baia MareRomania.

Pacus have become established in tropical Asia, including Thailand [59] and India. Pacu were introduced in to the Sepik Riverand in to the Ramu river as a food source, due to overfishing of native species.

Local people blame the fish for outcompeting native species, including juvenile crocodiles, as well as for several attacks on humans. As a primarily vegetarian fish, red-bellied pacu, have also consumed the floating mats of vegetation in the Sepik River, which operated as fish nurseries and crocodile and bird nesting sites.As the name might suggest, these tropical fish, with their big beaks and bright colors, look like their land-based counterparts.

Parrotfish live in coral reefs and spend their days chomping down on coral. Hard coral is no match for the large beak of the parrotfish, which researchers have recently found is formed by some of the strongest teeth in the world. Parrotfish chew on coral all day, eating not only the hard calcium carbonate skeleton, but the soft-bodied organisms called polyps that cover the skeleton and the algae called zooxanthellae that live inside them and provide the coral with energy, as well as bacteria living inside the coral skeleton.

When parrotfish poop out the coral they eat, the soft tissues are absorbed and what remains comes out as sand-a lot of sand. In a year, one large parrotfish can produce 1, pounds kg of sand, the weight of a baby grand piano.

Each parrotfish has roughly 1, teeth, lined up in 15 rows and cemented together to form the beak structure, which they use for biting into the coral. When the teeth wear out, they fall to the ocean floor.

This isn't a problem for the parrotfish, though, because another row of teeth is right behind the first, just waiting to chow down on coral. Biophysicist Dr. Pupa Gilbert has known she wanted to study parrotfish teeth for a while. No one had measured just how hard, stiff, and tough these teeth are, so Dr. Gilbert got to work.

What she and other researchers from Lawrence Berkeley Laboratory and the University of Wisconsin - Madison found when they looked into the composition of parrotfish teeth was an intricate crystal structure. Parrotfish teeth are made of a material called fluorapatite which contains calcium, fluorine, phosphorous and oxygen, and is the second-hardest biomineral in the world. Fluorapatite scores a five on the Mohs' hardness scale, making their teeth harder than copper, silver and gold.

No biomineral in the world is stiffer than the tips of parrotfish teeth. The teeth can also withstand a lot of pressure. One square inch of parrotfish teeth can tolerate tons of pressure-equivalent to the weight of about 88 elephants. The team developed a tool in order to see the orientation of the crystals in the fluorapatite, called PIC mapping, and the Advanced Light Source.

This technology essentially takes pictures of the crystals, which are ordered stacks of atoms. It color-codes the measured orientations of the crystals, and creates a picture that looks a little bit like abstract art, but can tell the scientists a lot about the structure of the teeth. The structure of parrotfish teeth was one the researchers had never seen before, with the crystals oriented in interwoven bundles, which form a chainmail pattern.

The specific structure is one that could be mimicked to create abrasion-resistant moving parts, but Dr. Gilbert is much more interested in the research possibilities of the PIC mapping technology and what new structures she may be able to find. Next on her list: a closer look at human teeth and bones using the tool. While Dr. Gilbert does this, parrotfish continue to go about their days, almost constantly grazing on coral.

While parrotfish eat a lot of coral, they also eat the algae that grow on top of coral reefs. This cleaning function is important to the reefs' ecosystem survival. When the fish eat the algae that compete with the coral polyps, the coral is able to grow and is more resilient in the face of local stressors like pollution or warming.

In areas where overfishing has wiped out parrotfish populations, coral reef ecosystems are not as productive, and cannot sustain as much diverse life.All rights reserved. The beautifully colored parrot fish is known to change its shape, color, and even gender during its life. It's hard to decide which of the colorful parrotfish's many unique characteristics is most remarkable. Much of the sand in the parrotfish's range is actually the ground-up, undigested coral they excrete.

There's its sex, which they can change repeatedly throughout their lives, and their coloration and patterns, which are a classification nightmare, varying greatly, even among the males, females, and juveniles of the same species. Finally, there are the pajamas. Every night, certain species of parrotfish envelope themselves in a transparent cocoon made of mucous secreted from an organ on their head. Scientists think the cocoon masks their scent, making them harder for nocturnal predators, like moray eels, to find.
