ACB - Torposhark
The microshark has moved to new waters, with more prey but also more rough terrain and denser flora. Because of this, it has adapted a heat sensor near it's nose to detect pray easier. It also developed a flat and wider tail along with a slightly more sleek body shape to move around easier. If it could talk, it would yell at you to always use .pngs unless it's an animation which in that case use a .gif or an .apng.
