The Freshwater sawfish, or Largetooth sawfish, is a unique cartilaginous fish that is a member of the order Rajiformes which includes stingrays and guitarfishes. It is named for the long rostrum that bears "teeth" on either side. The sawfish uses this rostrum to swipe at and stun schooling fish and other prey items such as benthic invertebrates. The Freshwater sawfish is found in shallow estuarine waters in Africa, Asia and Australia and can live in both fresh and saltwater. It closely resembles the small tooth sawfish Pristis pectinata which is found off the coast of the Yucatan Peninsula.
The Flamboyant cuttlefish is aptly named for its flashy coloration, which can change in an instant. It is a small species found in sand or mud substrates in tropical waters from Indonesia, through Papua New Guinea to Australia. Its coloration may be a signal to potential predators as this deadly beauty is the only cuttlefish species known to be toxic. It has recently been bred in controlled aquarium environments and has long been a coveted aquarium species. The Flamboyant cuttlefish feeds on small shrimp and other invertebrates, and has specialized tentacles that shoot out and capture their unsuspecting prey. When threatened, the Flamboyant cuttlefish can produce an ink screen to avoid predation.
One of the most infamous of the world's venomous snakes, this species is the leading snakebite species in its habitat. It is found from southern Mexico down to Northern South America. Like rattlesnakes, cottonmouths, and copperheads, it is a pit viper, equipped with heat sensing organs in a cavity between their eyes and nostrils. Females grow much larger than males, weighing more than ten pounds, and have bigger heads and longer fangs. The haemotoxic venom causes severe tissue damage, and many fatalities have been recorded.
