Trachyrhamphus longirostris, also known as the long-head pipefish or straightstick pipefish, is a species of marine fish belonging to the family Syngnathidae. They can be found in muddy estuaries on the continental shelf throughout the Indo-Pacific from Eastern Africa to the Solomon Islands and Japan.[1] [2] The diet of Trachyrhamphus longirostris likely consists of small crustaceans.[3] Adult individuals can grow to be approximately 33 centimeters in length. Reproduction occurs through ovoviviparity in which males brood eggs before giving live birth.
