Everything You Need To Know (2026)"},"content":{"rendered":"\n

When I first got my axolotl, I gently picked it up and thought “wow, this thing feels squishy.”<\/p>\n\n\n\n

My friend looked at me and asked, “Does it even have bones? It feels like jelly.”<\/strong><\/p>\n\n\n\n

That’s a question tons of people ask. Do axolotls have bones or are they just soft blobs floating around?<\/p>\n\n\n\n

The answer: Yes, axolotls DO have bones. But young axolotls start with cartilage that slowly turns into bone as they grow up.<\/strong><\/p>\n\n\n\n

Let me explain exactly how their skeleton works and why it matters for keeping them healthy.<\/p>\n\n\n\n

Yes, Axolotls Have A Full Skeleton<\/h2>\n\n\n\n

Axolotls are vertebrates animals with a backbone. They have a complete skeleton inside their body including:<\/p>\n\n\n\n

    \n
  • Skull bones<\/li>\n\n\n\n
  • Spine (vertebrae)<\/li>\n\n\n\n
  • Rib bones<\/li>\n\n\n\n
  • Leg bones (four legs with toes)<\/strong><\/li>\n\n\n\n
  • Jaw bones with teeth<\/li>\n\n\n\n
  • Tail bones<\/li>\n<\/ul>\n\n\n\n

    Their skeleton structure is similar to other salamanders and even has similarities to human bone structure. They’re not boneless creatures.<\/p>\n\n\n\n

    But here’s the interesting part that confuses people.<\/p>\n\n\n\n

    Baby Axolotls Start With Cartilage, Not Bone<\/h2>\n\n\n\n

    When axolotls are babies, their skeleton is made mostly of cartilage. Cartilage is the same flexible material in your nose and ears.<\/p>\n\n\n\n

    This cartilage skeleton is soft and bendy. That’s why young axolotls feel squishy when you touch them.<\/p>\n\n\n\n

    The Transition From Cartilage To Bone<\/h3>\n\n\n\n

    As axolotls grow and mature, something cool happens. The cartilage slowly transforms into real bone through a process called ossification.<\/p>\n\n\n\n

    Here’s how it works by age:<\/p>\n\n\n\n

    Under 4 cm length (babies)<\/strong>: Skeleton is 100% cartilage 6-10 cm length (juveniles)<\/strong>: Bone starts forming in the middle of long bones 10+ cm length (reaching maturity)<\/strong>: Cartilage gradually gets replaced by bone Adults (18 months+)<\/strong>: Most of the skeleton is bone, but some cartilage remains<\/p>\n\n\n\n

    Even adult axolotls that are 5-8 years old keep some cartilage at the ends of their bones. They never fully ossify like mammals do.<\/p>\n\n\n\n

    This is totally normal. It’s just how amphibian skeletons work.<\/p>\n\n\n\n

    Why Young Axolotls Feel Soft<\/h2>\n\n\n\n

    If you’ve ever held a baby axolotl, you know they feel super delicate and soft. There are two reasons:<\/p>\n\n\n\n

    1. Cartilage Is Flexible<\/h3>\n\n\n\n

    Cartilage doesn’t feel hard like bone. It bends easily and has a rubbery texture.<\/p>\n\n\n\n

    When your axolotl is young and mostly cartilage, it feels soft to the touch.<\/p>\n\n\n\n

    2. Thin Delicate Skin<\/h3>\n\n\n\n

    Axolotls have incredibly thin skin with no scales or protective coating. You can almost see through it on light-colored morphs.<\/p>\n\n\n\n

    This thin skin combined with a cartilage skeleton makes young axolotls feel fragile. And honestly, they ARE fragile.<\/p>\n\n\n\n

    That’s why you should avoid handling axolotls unless absolutely necessary. Their soft bodies can get injured easily.<\/p>\n\n\n\n

    What Axolotl Bones Look Like<\/h2>\n\n\n\n

    I’ve seen X-rays and CT scans of axolotl skeletons. They’re fascinating.<\/p>\n\n\n\n

    The Skull<\/h3>\n\n\n\n

    Axolotl skulls have multiple bone plates that form the head structure. They have eye sockets, jaw bones, and teeth attached to the bone.<\/p>\n\n\n\n

    Even adult axolotls maintain something called Meckel’s cartilage in their jaw – a cartilage rod that stays soft their whole life.<\/p>\n\n\n\n

    The Spine<\/h3>\n\n\n\n

    The backbone (vertebral column) runs from head to tail. Each vertebra is a separate bone that protects the spinal cord.<\/p>\n\n\n\n

    Young axolotls have cartilaginous vertebrae. As they mature, these slowly ossify into proper bone.<\/p>\n\n\n\n

    Leg Bones<\/h3>\n\n\n\n

    Axolotls have four legs with bones similar to human arm and leg structure:<\/p>\n\n\n\n

      \n
    • Upper bone (humerus\/femur)<\/strong><\/li>\n\n\n\n
    • Two lower bones (radius and ulna\/tibia and fibula)<\/li>\n\n\n\n
    • Wrist\/ankle bones<\/li>\n\n\n\n
    • Toe bones (four toes on front legs, five on back legs)<\/li>\n<\/ul>\n\n\n\n

      In juveniles, these leg bones are mostly cartilage. In adults, they develop a hard bone outer layer with a marrow cavity inside.<\/p>\n\n\n\n

      Ribs And Other Bones<\/h3>\n\n\n\n

      They have small rib bones attached to their spine. These ribs are short and don’t wrap around the body like human ribs.<\/p>\n\n\n\n

      They also have gill support bones (though these are partly cartilage) and bones in their tail.<\/p>\n\n\n\n

      The Amazing Bone Regeneration Power<\/h2>\n\n\n\n

      Here’s where axolotl bones get really wild.<\/p>\n\n\n\n

      Axolotls can completely regrow lost bones. If you cut off a leg, they’ll regenerate the entire limb including every single bone.<\/p>\n\n\n\n

      How Bone Regeneration Works<\/h3>\n\n\n\n

      When an axolotl loses a limb:<\/p>\n\n\n\n

      Week 1-2<\/strong>: The wound heals and forms a growth cap called a blastema
      Week 3-4<\/strong>: New cartilage starts forming in the blastema
      Week 5-8<\/strong>: The cartilage shapes into the missing bones
      Week 8-12<\/strong>: The new cartilage slowly ossifies into bone
      Month 3-4<\/strong>: The regenerated bone integrates with the old bone<\/p>\n\n\n\n

      The new bone connects perfectly with the original skeleton. It’s like the injury never happened.<\/p>\n\n\n\n

      I’ve watched my axolotl regrow a leg after another one bit it off. The bone came back completely normal. Scientists study this constantly trying to figure out how they do it.<\/p>\n\n\n\n

      Why Cartilage To Bone Matters For Health<\/h2>\n\n\n\n

      Understanding axolotl bone development helps you care for them better.<\/p>\n\n\n\n

      Young Axolotls Need Extra Care<\/h3>\n\n\n\n

      Since baby axolotls have soft cartilage skeletons, they’re more prone to injury.<\/p>\n\n\n\n

      Avoid:<\/p>\n\n\n\n

        \n
      • Rough handling<\/li>\n\n\n\n
      • Sharp decorations in the tank<\/li>\n\n\n\n
      • Aggressive tank mates<\/li>\n\n\n\n
      • Dropping them<\/li>\n<\/ul>\n\n\n\n

        Their soft skeleton can get damaged easily. Handle with extreme care or don’t handle at all.<\/p>\n\n\n\n

        Adults Have Stronger Skeletons<\/h3>\n\n\n\n

        Once your axolotl reaches 10+ cm and starts ossifying, the skeleton gets stronger and more rigid.<\/p>\n\n\n\n

        Adult axolotls with bone can handle slightly more stress than babies. But they’re still delicate compared to fish or reptiles.<\/p>\n\n\n\n

        Calcium Is Important<\/h3>\n\n\n\n

        Bones need calcium to form properly. Axolotls get calcium from:<\/p>\n\n\n\n

          \n
        • Their food (worms, pellets)<\/li>\n\n\n\n
        • Water (dissolved minerals)<\/li>\n\n\n\n
        • Cuttlebone (if you provide one)<\/li>\n<\/ul>\n\n\n\n

          Make sure your axolotl eats a varied diet with good nutrition. This supports healthy bone development as they grow.<\/p>\n\n\n\n

          Common Bone Problems In Axolotls<\/h2>\n\n\n\n

          Sometimes axolotl bones don’t develop correctly or get injured.<\/p>\n\n\n\n

          Metabolic Bone Disease<\/h3>\n\n\n\n

          This happens when axolotls don’t get enough calcium or vitamin D. Their bones become weak and deformed.<\/p>\n\n\n\n

          Signs include:<\/p>\n\n\n\n

            \n
          • Curved spine<\/li>\n\n\n\n
          • Weak legs that can’t support body weight<\/li>\n\n\n\n
          • Difficulty swimming<\/li>\n\n\n\n
          • Soft jaw<\/li>\n<\/ul>\n\n\n\n

            Prevention: Feed high-quality food and maintain good water parameters.<\/p>\n\n\n\n

            Bone Fractures<\/h3>\n\n\n\n

            Axolotls can break bones if they’re dropped or if something heavy falls on them.<\/p>\n\n\n\n

            Good news: They usually heal fractures on their own through regeneration. The broken bone repairs itself over several weeks.<\/p>\n\n\n\n

            Delayed Ossification<\/h3>\n\n\n\n

            Some axolotls take longer than normal to develop bone. This can happen from:<\/p>\n\n\n\n

              \n
            • Poor nutrition<\/li>\n\n\n\n
            • Cold water (slows metabolism)<\/li>\n\n\n\n
            • Genetics<\/li>\n<\/ul>\n\n\n\n

              As long as they’re eating well and healthy otherwise, slow ossification isn’t usually a problem.<\/p>\n\n\n\n

              How To Support Healthy Bone Growth<\/h2>\n\n\n\n

              Want your axolotl to develop strong bones? Here’s what to do:<\/p>\n\n\n\n

              Feed Quality Food<\/h3>\n\n\n\n

              Give them:<\/p>\n\n\n\n

                \n
              • Earthworms (high in calcium)<\/li>\n\n\n\n
              • Bloodworms<\/li>\n\n\n\n
              • Axolotl pellets (fortified with vitamins)<\/li>\n\n\n\n
              • Occasional brine shrimp<\/li>\n<\/ul>\n\n\n\n

                Vary the diet. Don’t feed only one thing.<\/p>\n\n\n\n

                Maintain Proper Water Temperature<\/h3>\n\n\n\n

                Keep water between 60-64\u00b0F. This temperature range supports normal metabolism and bone development.<\/p>\n\n\n\n

                Too cold = slow bone growth Too warm = stress and health problems<\/p>\n\n\n\n

                Keep Water Clean<\/h3>\n\n\n\n

                Do weekly 20% water changes. Clean water prevents disease that can affect bone health.<\/p>\n\n\n\n

                Test water parameters regularly:<\/p>\n\n\n\n

                  \n
                • Ammonia: 0<\/li>\n\n\n\n
                • Nitrite: 0<\/li>\n\n\n\n
                • Nitrate: under 20 ppm<\/li>\n\n\n\n
                • pH: 6.5-8.0<\/li>\n<\/ul>\n\n\n\n

                  Provide A Safe Environment<\/h3>\n\n\n\n

                  Use soft substrate like fine sand or go bare bottom. Avoid gravel – axolotls eat it and it can cause impaction.<\/p>\n\n\n\n

                  Remove any sharp decorations that could injure their soft bodies and developing bones.<\/p>\n\n\n\n

                  Don’t Handle Unnecessarily<\/h3>\n\n\n\n

                  Every time you pick up your axolotl, you risk damaging their delicate skeleton, especially when young.<\/p>\n\n\n\n

                  Only handle when absolutely needed for tank maintenance or health checks.<\/p>\n\n\n\n

                  Do All Amphibians Have This Bone Development?<\/h2>\n\n\n\n

                  The cartilage-to-bone transition is common in amphibians, but axolotls do it differently.<\/p>\n\n\n\n

                  Most Salamanders Fully Ossify<\/h3>\n\n\n\n

                  Regular salamanders that metamorphose into land animals develop full bony skeletons as adults.<\/p>\n\n\n\n

                  Their bones become completely hard because they need to support their weight on land.<\/p>\n\n\n\n

                  Axolotls Keep Some Cartilage Forever<\/h3>\n\n\n\n

                  Since axolotls never leave water, they don’t need fully rigid skeletons.<\/p>\n\n\n\n

                  Water supports their body weight, so some flexibility is fine. That’s why they keep cartilage at bone ends even as old adults.<\/p>\n\n\n\n

                  This is part of their neoteny – staying in a juvenile form forever.<\/p>\n\n\n\n

                  The Bottom Line<\/h2>\n\n\n\n

                  Let me make this super clear:<\/p>\n\n\n\n

                  Axolotls DO have bones. They’re not boneless.<\/strong><\/p>\n\n\n\n

                  But they start life with a cartilage skeleton that slowly ossifies into bone as they mature. Even adults keep some cartilage mixed with bone.<\/p>\n\n\n\n

                  Their skeleton is:<\/p>\n\n\n\n

                    \n
                  • Soft and cartilaginous when young (under 10 cm)<\/li>\n\n\n\n
                  • Gradually ossifying as they grow (10-20 cm)<\/li>\n\n\n\n
                  • Mostly bone with some cartilage as adults (20+ cm)<\/li>\n<\/ul>\n\n\n\n

                    This unique skeletal system is one reason axolotls can regenerate lost limbs so well. The combination of cartilage and bone gives them flexibility and the ability to rebuild damaged parts.<\/p>\n\n\n\n

                    Understanding this helps you handle them properly and provide the right care for healthy bone development.<\/p>\n\n\n\n

                    Quick Answer Summary<\/h2>\n\n\n\n

                    Question<\/strong>: Do axolotls have bones?<\/p>\n\n\n\n

                    Answer<\/strong>: Yes, axolotls have a complete skeleton with bones. Young axolotls start with mostly cartilage that slowly turns into bone as they grow. Adults have a mix of bone and cartilage. They can regenerate lost bones completely if injured.<\/p>\n\n\n\n

                    Key Points<\/strong>: Handle gently, feed calcium-rich foods, maintain proper water conditions to support healthy bone development.<\/p>\n\n\n\n

                    \n\n\n\n

                    Frequently Asked Questions<\/h2>\n\n\n\n

                    Are baby axolotls boneless?<\/strong> No, but their skeleton is mostly soft cartilage. Real bone develops as they grow, usually starting around 6-10 cm in length.<\/p>\n\n\n\n

                    Can you feel axolotl bones?<\/strong> In adults, yes – you can feel the harder bone structure. In juveniles, they feel soft because they’re mostly cartilage.<\/p>\n\n\n\n

                    Do axolotls have a backbone?<\/strong> Yes, axolotls have a vertebral column (spine) made of individual vertebrae that runs from head to tail.<\/p>\n\n\n\n

                    Why do axolotls feel squishy?<\/strong> Young axolotls have cartilage skeletons plus thin delicate skin, making them feel soft. Adults feel firmer as bone develops.<\/p>\n\n\n\n

                    Can axolotl bones heal if broken?<\/strong> Yes, axolotls can regenerate and repair broken bones through their amazing healing abilities.<\/p>\n\n\n\n

                    What bones do axolotls keep as cartilage?<\/strong> Even adults maintain cartilage at the ends of long bones (epiphyses) and in parts of the jaw and skull.<\/p>\n\n\n\n

                    Do axolotls need calcium supplements?<\/strong> Not if they eat a varied diet of worms and quality pellets. Their food provides enough calcium for healthy bones.<\/p>\n\n\n\n

                    At what age do axolotl bones fully develop?<\/strong> Bone formation starts around 10 cm length and continues throughout life, but they never fully ossify like mammals do.<\/p>\n","protected":false},"excerpt":{"rendered":"
