 The 𝐝𝐰𝐚𝐫𝐟 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡 (𝐂𝐚𝐫𝐢𝐧𝐨𝐭𝐞𝐭𝐫𝐚𝐨𝐝𝐨𝐧 𝐭𝐫𝐚𝐯𝐚𝐧𝐜𝐨𝐫𝐢𝐜𝐮𝐬), also known as the 𝐌𝐚𝐥𝐚𝐛𝐚𝐫 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡, 𝐩𝐲𝐠𝐦𝐲 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡, or 𝐩𝐞𝐚 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡,is a 𝐬𝐦𝐚𝐥𝐥 𝐟𝐫𝐞𝐬𝐡𝐰𝐚𝐭𝐞𝐫 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡 𝐞𝐧𝐝𝐞𝐦𝐢𝐜 to 𝐊𝐞𝐫𝐚𝐥𝐚 and 𝐬𝐨𝐮𝐭𝐡𝐞𝐫𝐧 𝐊𝐚𝐫𝐧𝐚𝐭𝐚𝐤𝐚 in 𝐒𝐨𝐮𝐭𝐡𝐰𝐞𝐬𝐭 𝐈𝐧𝐝𝐢𝐚. They are 𝐩𝐨𝐩𝐮𝐥𝐚𝐫 in 𝐚𝐪𝐮𝐚𝐫𝐢𝐚 for their 𝐛𝐫𝐢𝐠𝐡𝐭 𝐜𝐨𝐥𝐨𝐮𝐫𝐬 and 𝐬𝐦𝐚𝐥𝐥 𝐬𝐢𝐳𝐞.At a 𝐦𝐚𝐱𝐢𝐦𝐮𝐦 𝐭𝐨𝐭𝐚𝐥 𝐥𝐞𝐧𝐠𝐭𝐡 of 𝟑.𝟓 𝐜𝐦, 𝐝𝐰𝐚𝐫𝐟 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡 are one of the 𝐬𝐦𝐚𝐥𝐥𝐞𝐬𝐭 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡 in the 𝐰𝐨𝐫𝐥𝐝. 

The 𝐦𝐚𝐱𝐢𝐦𝐮𝐦 𝐝𝐨𝐜𝐮𝐦𝐞𝐧𝐭𝐞𝐝 𝐬𝐢𝐳𝐞 is 𝟑.𝟓 𝐜𝐦 in 𝐭𝐨𝐭𝐚𝐥 𝐥𝐞𝐧𝐠𝐭𝐡 with individuals typically reaching 𝐥𝐞𝐬𝐬 𝐭𝐡𝐚𝐧 𝟐.𝟓 𝐜𝐦.𝐁𝐨𝐭𝐡 𝐬𝐞𝐱𝐞𝐬 are 𝐩𝐫𝐢𝐦𝐚𝐫𝐢𝐥𝐲 𝐠𝐫𝐞𝐞𝐧𝐢𝐬𝐡-𝐲𝐞𝐥𝐥𝐨𝐰, with 𝐝𝐚𝐫𝐤 𝐠𝐫𝐞𝐞𝐧 to 𝐛𝐫𝐨𝐰𝐧-𝐛𝐥𝐚𝐜𝐤 𝐢𝐫𝐢𝐝𝐞𝐬𝐜𝐞𝐧𝐭 𝐩𝐚𝐭𝐜𝐡𝐞𝐬 on the 𝐟𝐥𝐚𝐧𝐤𝐬 and 𝐝𝐨𝐫𝐬𝐚𝐥 𝐬𝐮𝐫𝐟𝐚𝐜𝐞.Their 𝐩𝐞𝐜𝐭𝐨𝐫𝐚𝐥 𝐟𝐢𝐧𝐬 are 𝐬𝐡𝐨𝐫𝐭, 𝐟𝐚𝐧-𝐬𝐡𝐚𝐩𝐞𝐝, and described as"𝐬𝐥𝐢𝐠𝐡𝐭𝐥𝐲 𝐞𝐦𝐚𝐫𝐠𝐢𝐧𝐚𝐭𝐞".The 𝐝𝐨𝐫𝐬𝐚𝐥 and 𝐚𝐧𝐚𝐥 𝐟𝐢𝐧𝐬 are 𝐬𝐢𝐭𝐮𝐚𝐭𝐞𝐝 𝐨𝐩𝐩𝐨𝐬𝐢𝐭𝐞 𝐞𝐚𝐜𝐡 𝐨𝐭𝐡𝐞𝐫 toward the 𝐩𝐨𝐬𝐭𝐞𝐫𝐢𝐨𝐫 of the fish, 𝐛𝐨𝐭𝐡 𝐬𝐡𝐨𝐫𝐭 and 𝐫𝐨𝐮𝐧𝐝, while the 𝐜𝐚𝐮𝐝𝐚𝐥 𝐟𝐢𝐧 is 𝐥𝐚𝐫𝐠𝐞𝐫 than the 𝐨𝐭𝐡𝐞𝐫 𝐟𝐢𝐧𝐬 and 𝐭𝐫𝐮𝐧𝐜𝐚𝐭𝐞.Their 𝐛𝐨𝐝𝐢𝐞𝐬 are 𝐫𝐨𝐮𝐧𝐝 and 𝐨𝐛𝐥𝐨𝐧𝐠.

They are a 𝐩𝐨𝐭𝐚𝐦𝐨𝐝𝐫𝐨𝐦𝐨𝐮𝐬 𝐬𝐩𝐞𝐜𝐢𝐞𝐬, meaning they 𝐦𝐢𝐠𝐫𝐚𝐭𝐞 𝐰𝐢𝐭𝐡𝐢𝐧 𝐟𝐫𝐞𝐬𝐡𝐰𝐚𝐭𝐞𝐫 𝐫𝐢𝐯𝐞𝐫 𝐬𝐲𝐬𝐭𝐞𝐦𝐬, and are 𝐞𝐧𝐝𝐞𝐦𝐢𝐜 to 𝐫𝐢𝐯𝐞𝐫𝐬, 𝐥𝐚𝐤𝐞𝐬, and 𝐞𝐬𝐭𝐮𝐚𝐫𝐢𝐞𝐬 in 𝐊𝐞𝐫𝐚𝐥𝐚 and 𝐬𝐨𝐮𝐭𝐡𝐞𝐫𝐧 𝐊𝐚𝐫𝐧𝐚𝐭𝐚𝐤𝐚 in the 𝐖𝐞𝐬𝐭𝐞𝐫𝐧 𝐆𝐡𝐚𝐭𝐬 of 𝐏𝐞𝐧𝐢𝐧𝐬𝐮𝐥𝐚𝐫 𝐈𝐧𝐝𝐢𝐚.They can be 𝐟𝐨𝐮𝐧𝐝 in waters with a 𝐩𝐇 of 𝟕.𝟓–𝟖.𝟑 and 𝐭𝐞𝐦𝐩𝐞𝐫𝐚𝐭𝐮𝐫𝐞𝐬 of 𝟐𝟐–𝟐𝟖 °𝐂.They inhabit 𝐡𝐞𝐚𝐯𝐢𝐥𝐲 𝐯𝐞𝐠𝐞𝐭𝐚𝐭𝐞𝐝 𝐰𝐚𝐭𝐞𝐫𝐬 with 𝐛𝐞𝐝𝐬 of 𝐠𝐫𝐚𝐯𝐞𝐥 and 𝐫𝐨𝐜𝐤 or 𝐜𝐥𝐚𝐲 𝐥𝐨𝐚𝐦 with 𝐬𝐢𝐥𝐭 and 𝐬𝐚𝐧𝐝.

𝐃𝐰𝐚𝐫𝐟 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡 are 𝐞𝐮𝐫𝐲𝐩𝐡𝐚𝐠𝐨𝐮𝐬 𝐜𝐚𝐫𝐧𝐢𝐯𝐨𝐫𝐞𝐬. They 𝐟𝐚𝐯𝐨𝐮𝐫 𝐢𝐧𝐬𝐞𝐜𝐭 𝐥𝐚𝐫𝐯𝐚𝐞 but will rely on 𝐜𝐫𝐮𝐬𝐭𝐚𝐜𝐞𝐚𝐧𝐬 and 𝐚𝐧𝐧𝐞𝐥𝐢𝐝𝐬 as 𝐚𝐥𝐭𝐞𝐫𝐧𝐚𝐭𝐞 𝐟𝐞𝐞𝐝 when the 𝐚𝐯𝐚𝐢𝐥𝐚𝐛𝐢𝐥𝐢𝐭𝐲 of 𝐩𝐫𝐞𝐟𝐞𝐫𝐚𝐛𝐥𝐞 𝐩𝐫𝐞𝐲 𝐝𝐞𝐜𝐫𝐞𝐚𝐬𝐞𝐬.Their 𝐝𝐢𝐞𝐭 in the 𝐰𝐢𝐥𝐝 mainly consists of 𝐬𝐦𝐚𝐥𝐥 𝐚𝐧𝐢𝐦𝐚𝐥𝐬 like 𝐰𝐚𝐭𝐞𝐫 𝐟𝐥𝐞𝐚𝐬, 𝐫𝐨𝐭𝐢𝐟𝐞𝐫𝐬, 𝐜𝐨𝐩𝐞𝐩𝐨𝐝𝐬, 𝐬𝐞𝐞𝐝 𝐬𝐡𝐫𝐢𝐦𝐩, and 𝐚𝐪𝐮𝐚𝐭𝐢𝐜 𝐥𝐚𝐫𝐯𝐚𝐞 like those of 𝐎𝐝𝐨𝐧𝐚𝐭𝐚, 𝐇𝐞𝐦𝐢𝐩𝐭𝐞𝐫𝐚, 𝐦𝐚𝐲𝐟𝐥𝐢𝐞𝐬, and 𝐟𝐥𝐢𝐞𝐬, with some amounts of 𝐩𝐥𝐚𝐧𝐭 𝐦𝐚𝐭𝐭𝐞𝐫, largely 𝐝𝐢𝐚𝐭𝐨𝐦𝐬 and 𝐠𝐫𝐞𝐞𝐧 𝐚𝐥𝐠𝐚𝐞.

𝐀𝐥𝐥 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡 can 𝐢𝐧𝐟𝐥𝐚𝐭𝐞, or "𝐩𝐮𝐟𝐟 𝐮𝐩", their 𝐛𝐨𝐝𝐢𝐞𝐬 by 𝐪𝐮𝐢𝐜𝐤𝐥𝐲 𝐢𝐧𝐠𝐞𝐬𝐭𝐢𝐧𝐠 𝐥𝐚𝐫𝐠𝐞 𝐚𝐦𝐨𝐮𝐧𝐭𝐬 of 𝐰𝐚𝐭𝐞𝐫 into their 𝐡𝐢𝐠𝐡𝐥𝐲 𝐞𝐥𝐚𝐬𝐭𝐢𝐜 𝐬𝐭𝐨𝐦𝐚𝐜𝐡𝐬.Like many other pufferfish,in the 𝐚𝐛𝐬𝐞𝐧𝐜𝐞 of 𝐬𝐜𝐚𝐥𝐞𝐬, 𝐝𝐰𝐚𝐫𝐟 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡 have 𝐬𝐤𝐢𝐧 𝐬𝐩𝐢𝐧𝐞𝐬 on 𝐦𝐨𝐬𝐭 of their 𝐛𝐨𝐝𝐲.These 𝐬𝐩𝐢𝐧𝐞𝐬 become 𝐞𝐫𝐞𝐜𝐭 when the 𝐟𝐢𝐬𝐡 is 𝐢𝐧𝐟𝐥𝐚𝐭𝐞𝐝. 𝐃𝐰𝐚𝐫𝐟 𝐩𝐮𝐟𝐟𝐞𝐫𝐟𝐢𝐬𝐡,like many other 𝐓𝐞𝐭𝐫𝐚𝐨𝐝𝐨𝐧𝐭𝐢𝐟𝐨𝐫𝐦𝐞𝐬, 𝐩𝐫𝐨𝐝𝐮𝐜𝐞 𝐭𝐞𝐭𝐫𝐨𝐝𝐨𝐭𝐨𝐱𝐢𝐧,a 𝐡𝐢𝐠𝐡𝐥𝐲 𝐥𝐞𝐭𝐡𝐚𝐥 𝐧𝐞𝐮𝐫𝐨𝐭𝐨𝐱𝐢𝐧 for which there is 𝐧𝐨 𝐚𝐧𝐭𝐢𝐝𝐨𝐭𝐞.These 𝐭𝐫𝐚𝐢𝐭𝐬 are 𝐚𝐧𝐭𝐢-𝐩𝐫𝐞𝐝𝐚𝐭𝐨𝐫 𝐚𝐝𝐚𝐩𝐭𝐚𝐭𝐢𝐨𝐧𝐬.
