Today (17th October) is the very first #IntlSawfishDay !
International Sawfish Day is an event created in partnership with the Sawfish Conservation Society, the European and American Associations of Zoos and Aquariums who want to raise awareness for Sawfishes.
The aim is to educate people on the threats they face as well as developing conservation strategies that will protect them.
Sawfish are large, shark-like rays of warm, shallow, coastal waters, estuaries, and rivers. Their tooth-studded snouts (rostra), which are easily entangled in fishing gear, and their low reproductive rates make them exceptionally susceptible to overfishing. Sawfish are also threatened by degradation of habitats such as mangroves. There are only five species of Sawfish in the world – the Knifetooth Sawfish (Anoxypristis cuspidata) and Dwarf Sawfish (Pristis clavata) are classified in the IUCN Red List as Endangered, while the Smalltooth Sawfish (Pristis pectinata), Largetooth Sawfish (Pristis pristis) and Green Sawfish (Pristis zijsron) are Critically Endangered. They are considered the most threatened elasmobranchs (sharks and rays) in the world due to destructive fishing practises, habitat destruction and the curio trade.
The various Sawfish species range from 1.4 metres to 7.5 metres in length, making them true #megafish . They can be found in inshore coastal areas such as coastal lagoons, estuarine environments, and brackish river deltas, although they may also swim up rivers into freshwater environments. Sawfishes prefer shallow, muddy, brackish water, spending most of their time on or near the seabed. The rostrum contains extensive sensory organs that can detect the minute electrical signals from prey. It is used to ‘club’ fish - stunning or killing them before they are eaten.
Three species of Sawfish were historically recorded in Singapore waters - the Knifetooth, Largetooth, and Green Sawfishes. However, they are now extremely rare, if not already locally extinct; the last record was in 2001. Sadly, Sawfishes have already disappeared from most of the areas where they were once found, and more needs to be done to protect the few surviving populations around the world.
Here's a short video of a Freshwater #Sawfish from the Kimberley region of Western #Australia - the #GoPro still bears a scratch! All #species of #sawfishes are listed as #Endangered or #CriticallyEndangered by the #IUCN , and face the threat of #extinction as a result of #habitat loss and #overfishing . Global populations of every species of sawfishes are estimated to have fallen to less than 10% of their historic levels, and they have been lost from at least 80% of their historic range. The smalltooth #sawfish (#Pristis pectinata), for example, was once widely distributed, but available data indicate the range of this species has been reduced by about 90%, and population numbers have declined dramatically, perhaps by 95% or more.

يتميز سمك المنشار بأنفه الذي يشبه المنشار، والذي يستخدمه لتتبع حركة فرائسه عند اختبائها، ويستخدمه أيضاً كأداة للحفر وللدفاع عن نفسه ضد الحيوانات المفترسة مثل أسماك القرش. كما أن هذا النوع محمي بموجب القانون، فإذا شاهدتموه، نرجو الاتصال بهيئة البيئة - أبوظبي على رقم ٨٠٠٥٥٥. #بيئة_أبوظبي
The sawfish's most distinctive feature is its saw-like nose that is used to detect its preys movement when hiding, it’s also a digging tool, and uses its nose to defend itself against predators such as sharks. This species is protected by law and should you come in contact with them please report the sighting to EAD immediately at 800555. #EnvAgencyAD#sawfish#marinelife#sealife#endangered#species#environment#iucn#sharks#sawfishes#abudhabi#ead#uae
Here's something different than my normal posts. I am completely fascinated by Sawfish and their biology. These are two very small Rostrums (nose/bill) from a sawfish.
I do not and will not sell Sawfish Rostrums. The law is a mine field and I do not want to become tangled in that web. If however you come across a real antique specimen of one of these at an auction or a boot fair or anything as such, speak to the seller and get as much information from them as you can. Ideally you should have papers with this.
Sadly Sawfish have recently been listed as Critically endangered. They are population is believed to have dropped by 80% over the last 30-50 years. There are many different species of Sawfish but all of which are listed as critically endangered in CITES appendix 1.
