Biologists still have a lot to learn about smalltooth sawfish biology and ecology, but research conducted over the last two decades has improved our understanding of the species.
Smalltooth sawfish can grow very large, up to 17 feet 5. They have 21 to 30 unpaired teeth on each side of the rostrum saw ; males typically have more rostral teeth than females. If completely lost, the teeth are not replaced; if teeth are only chipped and their bases are intact, they will continue to grow as the animal grows. Smalltooth sawfish of all sizes feed primarily on fishes such as mullet and rays, using the rostrum saw to slash through schools of fish, stunning them before they are consumed.
Like other rays and sharks, sawfish take several years to reach maturity and are long-lived. Biologists are not certain of the size of smalltooth sawfish at maturity, but males appear to mature around 11 feet long 3. Females reproduce every other year and return to the same nurseries to give birth.
Like other rays and sharks, smalltooth sawfish have internal fertilization, and embryos grow inside the mother until they are born alive.
Smalltooth sawfish in Florida waters give birth primarily in April and May. Females can give birth to approximately 7—14 young measuring 2 to 2. Like many toothed fish, sawfish can replace their teeth if they are worn down or lost.
This phenomenon is called polyphyodonty. A groundbreaking bipartisan bill aims to address the looming wildlife crisis before it's too late, while creating sorely needed jobs. More than one-third of U. We're on the ground in seven regions across the country, collaborating with 52 state and territory affiliates to reverse the crisis and ensure wildlife thrive.

Description Sawfish are part of the Rajiformes order—a group of flattened marine fish that include rays and skates—and are closely related to sharks. Population monitoring through encounter records provided by the public.
Three National Wildlife Refuges in Florida protect smalltooth sawfish habitat. If you visit these refuges or other shallow, coastal areas in southern Florida, remember to keep your distance from sawfish and respect their habitat. You can also help restore coastal habitats by participating in local mangrove planting and other habitat restoration projects, and by participating in coastal clean-ups. Under the Endangered Species Act, it is illegal to catch or harm an endangered sawfish.
Because fishermen may catch sawfish incidentally while fishing for other species, safe handling and release guidelines have been developed so they can quickly release hooked sawfish with little or no harm.
Scientists at the Florida Fish and Wildlife Conservation Commission conduct research on smalltooth sawfish. As part of the research program, the Sawfish Survey asks fishermen, boaters, and beach-goers to report any sawfish they catch or see in the water. You can also make reports to sawfish MyFWC.
The U. The non-U. This means that both distinct population segments are in danger of extinction throughout all or a significant portion of their range. The goal of the smalltooth sawfish plan is to recover the U. We convened the Smalltooth Sawfish Recovery Team—consisting of scientists and environmental managers—to develop a recovery plan for this species. The team published the first Smalltooth Sawfish Recovery Plan in and is currently updating it to incorporate new information. Adam Brame , Recovery Coordinator.
The Smalltooth Sawfish Recovery and Implementation Team works with state and federal resource management agencies to develop regulations to reduce interactions between sawfish and commercial fisheries. The team also works with government agencies, conservation organizations, and fishing groups to implement an education and outreach plan. These efforts aim to increase awareness and help sawfish survive human interactions.
Those areas may be designated as critical habitat through a rulemaking process. The designation of an area as critical habitat does not create a closed area, marine protected area, refuge, wilderness reserve, preservation, or other conservation area; nor does the designation affect land ownership. Federal agencies that undertake, fund, or permit activities that may affect these designated critical habitat areas are required to consult with NOAA Fisheries to ensure that their actions do not adversely modify or destroy designated critical habitat.
We designated these areas because they provide important juvenile nursery habitat, where young sawfish can find food easily and avoid predators. View the smalltooth sawfish critical habitat map. A number of commercial fisheries incidentally catch smalltooth sawfish, as the species is extremely vulnerable to entanglement in nets, lines, and trawls.
Various fishing gear modifications and fishing regulations have been implemented to minimize the impacts to sawfish from the commercial fishing industry. For example, Florida has banned the use of gillnets in state waters. Safe handling and release guidelines also have been developed for fishermen.
These guidelines explain how to remove a sawfish from different types of fishing gear and also ask that fishermen record details about encounters in their logbooks. NOAA Fisheries provides protocols for commercial fishing vessels to reduce the impacts of hook-and-line gear on smalltooth sawfish. Find safe handling and release guidelines PDF, 1 page.
Because smalltooth sawfish accidentally caught while fishing must be released as quickly as possible, NOAA Fisheries developed guidelines explaining how recreational anglers can safely handle and release the species. Learn what to do if you accidentally catch a smalltooth sawfish PDF, 2 pages. Together with state partners and conservation groups, we have developed programs to educate the public about the endangered status of smalltooth sawfish, as well as prohibitions against capturing, harming, or harassing them.
Find educational materials. Through international cooperation and conservation efforts, NOAA Fisheries and the International Union for Conservation of Nature are working with our partners to protect smalltooth sawfish. Key policy recommendations and conservation activities include:. Training people in local fisheries to conduct sawfish surveys in key regions, including West Africa. To prevent illegal trade, creating manuals to help fishermen, customs agents, and enforcement personnel identify sawfish and sawfish parts.
Reducing sawfish bycatch in trawl and gillnet fisheries in southeast Asia and other bycatch hotspots around the world. Commercial trade in all sawfish, except for one Australian species traded for commercial aquaria, is prohibited. Some of our partners include the state of Florida as well as universities, nonprofits, and international organizations.
Sawfish researchers collect data from sawfish carcasses that are found and reported, sawfish incidentally caught in federal fisheries, and sawfish that are collected during field surveys for the species. Reported sawfish carcasses are necropsied and samples are collected that can aid in age growth models. These allow them to sense the electrical pulses from other creatures, which helps them find prey buried under the sand. Humans have single-handedly decimated the populations of every species of Sawfish.
Several different factors have gone into the demise of these creatures. People capture them on purpose to use their fins in shark fin soup, and to sell their saws as decorations. We also accidentally capture them in nets meant for other fish, or as bycatch.
Habitat destruction and climate change both impact these creatures as well. Humans destroy the estuaries and mangroves that these creatures use to hunt for food and their young use to hide from predators. Pollution and climate change impact both these fish and their prey as well. No, you cannot own any of the various species as a pet. Not only do they grow incredibly large, but every individual is important for the survival of the species.
Only a few aquariums house these creatures, and even then you can only find a few species. Various programs around the globe still hope to successfully implement breeding programs to save the species. These creatures are primarily solitary, and usually only congregate to breed.
