After V1 the First Officer and I noticed an odor that smelled wet; damp; musky; wet sock type of smell. This odor did not clear and remained strong throughout the duration of the flight. When we reached a safe altitude on departure; I contacted the Flight Attendant and asked if she smelled any odor or fumes. She replied positively. The FO and I requested priority handling and landed back in ZZZ. After landing; we taxied back to the gate. Speaking with the FA more after the emergency; she told us that there had been an odor during taxi and takeoff; with it increasing strongly on takeoff. The FA thought it was just her that smelled it and did not say anything; but confirmed she smelled the same odor mostly in the front to row 2A [I initially noticed] smell of fumes in cockpit and cabin. Requested priority handling; donned O2 mask; and landed in ZZZ. [My] suggestion is to emphasize in training to flight attendants if anything is out of the ordinary or unknown fumes are present to speak up and not be afraid to contact the flight deck in sterile if it may be a safety of flight issue.
EMB-145 Captain reported a strong 'wet sock' type smell during takeoff resulting in a return to the departure airport.
