They sometimes open separately into the gut, sometimes are united into larger trunks, and give rise to branched structures. They are most numerous in the Gadidae and Scom- beroi'dee. In many Fishes the different caeca are held together by connective tissue and united at a common efferent duct, in which case they have the appearance of a compact gland (Scomberoidse), while their affinity to the gland in the Sturgeon is implied by the frequent union of their orifices. In many Teleostei the mid-gut is much longer than the tract of the coelom which is given up to it, and it is then arranged in coils (Fig. 316, B i), or in several ascending and descending loops. This implies an adaptation to the cavity of the coelom, whilst the elongation of the tract, which is always derived from a straight.
